[00:00:08]So from unit number one in management science completely unit number one is complete theory no problematic nothing in long and short. Okay. From unit number one itself you can able to attempt for 16 marks weighted 12 marks long and four marks short. So unit one you should never skip a theory. Okay. So theory uh whatever I'm explaining in this uh uh class just make sure you understand the concepts. If you are understanding the concept no side headings and meaning and definition will be same for every question from unit number one. Just you need to remember the side headings and inside the matter you need to write it by your own. No. So that's why just understand the concept that is main important. Okay. Inside the matter of side headings you need to write it by your own. Okay. So when you are attempting theory from this unit number one for 12 marks three sides of the answer must and should for example this is your booklet this is one side this is second side and another side is third side okay three sides of the theory answer is must and should well marked and you can include certain kind of so whatever the side points you are having no just the side points you can write it in a diagrammatical representation also okay so this all techniques you need to use it when you are writing your theory answers not only in this subject even for other subjects also. So from unit number one in management science first the most important question is about the definition of production and operation management. Definitely you need to remember the definition of production and definition of operations management and everything. Okay. So what is mean by poom? Okay. PO together that means production and operations management together definitions. So production and operation management is a wider concept and combination of two similar functions like production and operations management together we are learning that. So POM production and operation management is a combination of two functions. One we will discuss about the production function and operations function together. Together if we are learning me that will become the production and operations management. So first you need to identify the what is the single meaning of production management. So production management is the management where it will be concerned about the inputs and outputs.

[00:02:41]Production management. For example, if you are starting a business now, how many inputs, how many inputs you are producing, how many you sold, what is the balance, good you are having, everything you will maintain, maintain a stock. No, maintain a thing. No. Yes. You'll maintain all the data. Yes. So that is called production management. How many you have produced? How many you have sold? What is the remaining stock? Everything raw materials, machines, men, method, everything inputs and outputs. It will show the relationship between the inputs and outputs that is called production management. Means you are managing your production. How many goods you are producing, how many goods you are selling, how many goods it is left over.

[00:03:27]Okay, you are managing that. That is called production management. So what is mean by operations management? Then operations management is nothing about the physical and or technical functions.

[00:03:38]Okay. Like to manufacture certain goods or services. What is the physical or technical functions you are using? Okay.

[00:03:47]To develop that to manage that thing that is called operations management.

[00:03:53]Okay. If together we are learning means that will become the POM that is production and operations management.

[00:04:00]What it will do? It will transform all inputs into outputs. Whatever the input, raw materials, machines, men work, everything that will become the output that is called production and operations management. One thing remember whatever the question you are attempting from unit number one theory in long or in short the meaning of PO the meaning of production management the meaning of operations management compulsory you need to write it not only this question any question from unit number one understood the meaning concept next if they are asking functions objectives scope nature advantages pages anything about the POM that is production and operation management you can write the side headings. First the side heading is about the planning means when you are starting any business when you are starting any organization first you should have the proper planning of what to do when to do how to do where to do who to do everything you need to have a proper planning without planning you will not segregate anything. Yes, when you want to study a subject, you will plan certain today we need to do first unit, tomorrow we need to do third unit like that. That is called planning. Next one, design and engineering. When you are developing a product, for example, you are developing a product. For example, you are um developing any milk packet. Okay. What is your planning uh to give a uh genuine good fat milk that is your planning? Design and engineering means what will be your label? Okay. How to design that process? Product design everything you will do that no that is a design and engineering. Next one production you will start the production yes or no. So that will organize all your resources that means right quantity at the right time at the right person for the best quality. Just just remember this meaning just just remember that the underlying. Okay. So right product at the right time to the right person at right quantity that is called production. Next one maintenance.

[00:06:12]Maintenance will be helpful for the organization to maintain a proper usage of plant and machinery. For example in your organization you are having any plant or if you are having any machinery okay you will maintain specifically correctly means you'll maintain properly. No. So whatever the production function we are having it will able to maintain the maintenance mean it will not failure mach we need to use it no okay that is called maintenance of your production machines. Next one procurement of raw materials. What is this procurement of raw materials? There are different types of raw materials like for example spare parts. We will have we will have the raw materials. We we need to understand the exact quantity to produce something. Okay. How much is the raw materials? Everything you need to understand that here itself you are having so many points like around you having 10 points. Okay. Remember any seven point that will be more than enough in your examination final examination meaning and definition of the uh that production function and operation function and pom and later on either if they asking objectives nature scope anything just remember seven to eight side headings remember the side heading and you need to inside the matter you should write by your own no need to by heart any answers just understanding the meaning writing by your own just two to three lines also So if you're writing it will be more than enough. Okay. Proper presentation is a very important in the subject. Okay.

[00:07:48]Next one. Logistics management. What is mean by this logistics management? From place of production to place of consumption. Whatever the transportation activities we are doing that is called logistics management. Whether we are concerned about the implementation of plant to control over the machineries or not. Whether the proper delivery is happening or not. That is also you need to maintain. Next one HRM human resource management that means to create to develop one product. How many humans are working to create that product to develop that product? How many raw materials are used? Okay. Without having a manpower, without having a proper manpower, how can you develop a product?

[00:08:33]Definitely no. Even though you are having thousand machines but minimum to minimum you should have the manpower.

[00:08:39]Okay. Humans we want to contribute something to develop the product. No that is called human resource management. HRM. Next one finance to maintain your organization.

[00:08:50]Definitely you should have the finance money you need to have it. No even if you're doing production even if you're doing for the sale whatever the expenses you need to bear all that. So for bearing all that you should have the finance. No. So finance plays a crucial role in the funds in the organization.

[00:09:08]Next one accounting proper transaction of your how many sales you have done, how many purchases you have done like that. Marketing means it will be helpful for the customers to identify your company's product.

[00:09:21]Marketing is also very important. Even if your product is very genuine with good quality also customers should know about your uh know about your good or service. So marketing is one of the main important things advertising policies procedures everything. So like this you are having the side heading. So remember any seven to eight heading of your own.

[00:09:42]Okay. So like that you need to remember.

[00:09:45]Next question is also same like that only objectives or nature of POM that is production and operations management.

[00:09:53]Here also you will have the competitive advantage service orientations will be there. Echofriendly that means your products your services should not harm the uh nature like we will get to know no eco-friendly products that means something the company is not misusing the nature means they are avoiding the plastics like that okay that is also one of the main features small is beautiful that means uh according to the uh author what he was saying means instead of developing a Big organization whatever the small organization you are having how much quantity we are producing is not important. How much quality of the goods or services you are producing is important. That is called small is beautiful. Okay. So like that you are having various side headings. No. So in that choose any seven to eight side headings clear objectives importance anything you can write all that comes in first question only. POM first need to understand write the meaning of production management operations management production and operations management meaning and definition then if they're asking nature co-op objectives advantages anything that's seven to eight points of your wish you can write it and you need to elaborate in three sides clear this is the first important question clear with first question everyone both of you >> clear ma'am [clears throat] second important Question is about the product life cycle. Very important question. Product life cycle. So a product will have a four stages. So according to the Philip Kler what he was saying means the product life cycle is an attempt to recognize in the different stages of the history of a product.

[00:11:44]Okay. Every product any product it might be it will pass through four stages.

[00:11:50]What is the four stages? Just if you are understanding this graph no easily you will understand the answer and you can elaborate by your own. See a a product will have a four four stages no introduction stage growth maturity and decline means first your product will increase introduction you introducing your product then it will slowly grow at certain point it will decline because of new product. Okay, maturity state we will call it as and decline means it is going to the down stage. So every product first it will have introduction then growth then maturity means something in equal then it will decline that is called four stages of product life cycle. PLC product life cycle in introduction stage awareness will be slow no so everyone risky and expensive stages will not be included like that you need to write two to three side headings like that growth stage means market will accept your product or a service automatically high competition will make in the organization maturity state means no profit no loss like simultaneously you are just you are in a middle position okay you are not getting much profit, much losses. You're in a uh slightly middle position. That is called maturity stage. And the last stage is decline stage. Every product at certain point it will go to the negative. Okay.

[00:13:18]First it will introduce then it will automatically grow then it will have a semi-auto profit then it will vanish off every product any product you can take. Okay.

[00:13:29]So this is very important second question. Okay. and product life cycle same here also this is not much important so that's it only two questions remember so what is the two questions one thing about the production and operations management second one is PLC product life cycle very important okay these two questions out of these two questions one question will be definitely for your 12 marks okay when they are asking the product life cycle this graph compulsory you need to draw it Clear and first question when you are drawing writing the answer whatever the side headings you are having make sure you draw it like in a flowchart neatly to present the meaning then definition then flowchart then explanation of the side heading like that all one answer should get covered in three sides of the pages very simple unit but in this unit itself you can score 16 marks you can attempt for 16 marks 12 marks long and four marks short also they will ask only these things Product life cycle means what uh what is mean by operations management? What is mean by POM? What is mean by life? That only they will ask in four marks also. So long questions if you are very perfect that means automatically you will attempt for four marks also. So when you are write when you are learning the theory questions you need to understand the concept you need to buy the meaning and definition and side heading inside the matters only you need to write by your own. Clear? So this is about unit number one in management science unit number in management science unit number two what is the problematic method we are having job sequencing this is the problematic method okay so here they have given the job how many jobs is there 1 2 3 4 5 and six total six jobs is there machine one and machine two is there so here we need to allot the job. Okay, we need to allot the jobs. What is the total and ideal time? If the question is like this, what is the solution? We need to do in step number one. Okay, how many jobs is there? Six jobs is there. No, in a box. Okay, in a box draw six columns. 1 2 3 4 5 and six. 1 2 3 4 5 and six. Why?

[00:15:57]Because it is a six jobs we are having.

[00:15:59]Okay. Out of six jobs, see here in machine one, 7 4 2 5 9 and 8. In machine 2, 3, 8, 6, 6, 4, 1. Yes. So out of this all machine one and machine two, what is the least number you are having? What is the least number?

[00:16:20]>> Can you tell me?

[00:16:23]>> One is the least number. Yes.

[00:16:27]>> Yes. In the sixth job in machine two, you are having the least number. Okay.

[00:16:34]So, first least number is coming from machine number two. So, what is the job number?

[00:16:39]>> Yes, ma'am.

[00:16:40]>> Six.

[00:16:41]>> Six.

[00:16:43]>> If the least number is from machine two, you need to write it from the last one onward. So, here you will write the six.

[00:16:52]>> Okay. Now this column is over because out of machine one and machine two mission two is small digit. Now after this what is the second least number you are having?

[00:17:05]>> Two ma'am >> two where it is there in job number three in machine one or machine two?

[00:17:14]>> Machine one ma'am.

[00:17:15]>> Machine one what I said if machine two is from here you need to write it. If machine one is from here you need to write it. So here you need to write three.

[00:17:25]Clear?

[00:17:27]>> Okay.

[00:17:28]>> If the small digit is from machine number one, you should write it from first onwards. If it is from machine, write it from last onwards. Okay. Now this two columns is over. Next release number is >> three. Yes.

[00:17:41]>> Three. Yes.

[00:17:45]>> Where it is there? In machine two, it is there. Where you will write one? Here.

[00:17:49]Here >> from the last >> from the last. Very good. So here you need to write one.

[00:17:56]>> Okay. After that what is the next list number?

[00:18:01]>> Next uh five member >> five. Four is there. But four you are having here and here. Okay.

[00:18:11]>> Yes.

[00:18:11]>> So if machine one means here you'll write two. If machine five is machine two is where you from here only know >> yes ma'am >> both are four one is machine one so that's why we are writing from first second is from machine two that's why we are writing it from last >> okay ma'am and last one is five in machine one it is there it will come from >> it is fourth job no >> yes ma'am this fourth job so what is the thing we got 3 2 4 5 1 and six.

[00:18:48]>> Yes.

[00:18:49]>> Here directly I have wrote in one column but in examination you need to show each and everyone. So first step number one we wrote six. Why you wrote six? The smallest processing time is six that is one you are getting from job number six.

[00:19:06]If it is machine number two mean we need to start it from the end like that you need to write statement.

[00:19:12]Okay.

[00:19:14]For each statement, for each, for each block, in step number one, only one. In step number two, only two. In step number three, only this, four, five, six. Like that. You need to write each and everything. And you need to give the suggestion why you have given that.

[00:19:28]Okay. The next processing list will be four. But here the both A and B are processing from like that. You need to give the statement by your own. Okay. So that step number one, you should not write it. You need to show the statements also. Why you are entering here? Why you are entering here? Why you entering here? Okay.

[00:19:46]>> Okay. After this simply, simply we need to draw the table mark. Okay. How many machines we are having?

[00:19:58]>> Two. You are having one minute.

[00:20:32]So first I'm writing the sequence.

[00:20:37]Okay.

[00:20:37]>> Yes. Then >> machine one and machine two. In machine one and machine two again four four columns will be there.

[00:20:47]See this is sequence.

[00:20:52]Okay. This is machine one. This is machine two. In machine one and machine two again four columns. 1 2 3 and four. 1 2 3 and four. What is the column name? First one is time in. Okay.

[00:21:15]Next one is processing time. Next one is time out. Next one is ideal time. Same here also. Time in crossing time. Time out. Ideal time. This is the column. So what is the we got?

[00:21:34]3 2 4 5 1 and >> this is the sequence we got. No.

[00:21:46]>> Yes.

[00:21:47]>> Yes.

[00:21:49]Now, now what you need to do means in machine one. Okay. What is the processing time units you are having? For example, what is the thing you are having here? Three nodes. Yes.

[00:22:03]Yes sir.

[00:22:04]>> Here you got three in machine number one and job three what you having here value?

[00:22:11]>> Two two >> two. So in processing time I'm writing two. Next you are having two. No >> in machine one job two what you are having in machine one job two four. Next five because it is a four. in one.

[00:22:33]>> Yes, ma'am.

[00:22:33]>> Next 9.

[00:22:39]>> Four. No.

[00:22:40]>> Seven.

[00:22:42]>> Eight. What happened?

[00:22:44]>> Here it is. Four. No.

[00:22:47]>> Machine one. Four. What you having?

[00:22:49]>> Five. So that's why five.

[00:22:51]>> Five.

[00:22:52]>> Next to five. Yes. In five what you having? Nine.

[00:22:56]>> In one you are having seven. In six you are having eight. Like the time right?

[00:23:01]>> Yes. Okay.

[00:23:02]>> Eight. Yes.

[00:23:03]>> Same. Same like machine two processing time also. Machine two processing time.

[00:23:09]>> Job number three. Machine number two.

[00:23:10]You are having six.

[00:23:14]>> Six.

[00:23:14]>> Next eight.

[00:23:18]Next again. Six.

[00:23:21]Next.

[00:23:25]Five. Four.

[00:23:28]One is three.

[00:23:30]6 is one. Understood?

[00:23:34]>> Yes ma'am.

[00:23:36]>> Okay. After writing this in machine one time one the first two value will become zero. What will become? It will become zero.

[00:23:48]>> Okay. So 0 + 2 is 2.

[00:23:53]>> 0 + 2 ma'am.

[00:23:57]two here. How to calculate this timing mean?

[00:24:02]Here you wrote zero. No. Okay. First value become zero.

[00:24:06]>> So 0.

[00:24:07]>> Yes.

[00:24:08]>> + 2 is here also it will become 2. So 2 + 4 >> 6.

[00:24:15]>> 6. 6 + 5 >> 11.

[00:24:22]>> 11 + 9 >> 20.

[00:24:25]>> 20.

[00:24:27]20 + 7 is >> 27.

[00:24:31]>> Clear? Like that you need to calculate.

[00:24:33]Now how you calculate time out? So 0 + 2 is 2.

[00:24:37]>> Yes ma'am.

[00:24:39]>> Yes ma'am.

[00:24:40]>> 2 + 4 is 2 + 4. Here you need to do all plus only. 6 + 5 11. 11 + 9 >> 20. 20 + 7 27 27 + 8 35.

[00:25:02]Clear?

[00:25:07]Understood?

[00:25:10]See become zero here. So 0 + 2 is 2. 2 + 4 + 4. How to calculate this column?

[00:25:18]Just like this.

[00:25:19]>> Adding row.

[00:25:20]>> Okay. Now yes, >> now how you will do ideal time in time out and time in you need to set it. For example, see here, here you are having two now.

[00:25:32]And what is the time in second one? Two.

[00:25:35]So 2 - 2 >> 0 >> 6 - 6 0 11 - 11 0. like this. You need to check out in cross order.

[00:25:51]>> Yes ma'am.

[00:25:52]>> 20 - 20.

[00:25:53]>> Okay.

[00:25:54]>> 0. 27 - 27.

[00:26:02]>> Okay.

[00:26:04]Here you are having last value. No.

[00:26:08]>> So in last value I'll let you know how how you need to do last. I will let you know. Okay. So till here you have understood.

[00:26:15]>> Okay.

[00:26:17]Now same here also. Now how you'll take this machine two means what is the time out of machine one?

[00:26:27]>> What is the time out of machine one?

[00:26:30]>> Time out.

[00:26:33]>> Two.

[00:26:35]Yes. Two only.

[00:26:38]>> Yes ma'am.

[00:26:38]>> Here you need to write time in two.

[00:26:43]Here whatever the value you are getting here. No. In time out of machine one that value will become time in for machine two. So 2 + 6 >> 8 >> 8 >> 8 + 8 is >> 16 >> 16 >> 16 + 6 is >> 22 22 + 4 is >> 26 >> 26 26 + 3 is >> 29 >> 2 Okay.

[00:27:14]>> Yes ma'am. 6 + 2 is 8. 8 + 8 is 16.

[00:27:18]>> 16 + 6 is 22. 22 + 4 is 26.

[00:27:22]>> 26 + 3 is 29.

[00:27:24]>> 20.

[00:27:25]>> 29 + 1 is 30.

[00:27:27]>> 30.

[00:27:28]>> Now how you calculate ideal time? This value and this value you will check it.

[00:27:32]No, same.

[00:27:34]>> Yes ma'am.

[00:27:35]>> So 8 - 8 is >> 0.

[00:27:38]>> 16 - 6 is 0.

[00:27:40]>> 0.

[00:27:41]>> 22 - 22 is 0. 26 - 26 is 0. 29 - 29 is >> 0.

[00:27:48]>> Okay. Like this all zeros will come.

[00:27:50]>> Okay.

[00:27:51]>> Okay. Now here, now here what is the last value here in time out? 30.

[00:28:00]>> Yes ma'am.

[00:28:03]>> Here what is the last time out in machine one?

[00:28:06]>> 35.

[00:28:08]>> 35. Yes.

[00:28:10]>> Yes ma'am. How you'll do mean 35 minus 30 you need to do it for the last value.

[00:28:17]How much you will get? Five you will get.

[00:28:20]>> Yes ma'am.

[00:28:22]>> Okay.

[00:28:23]>> Yes ma'am.

[00:28:24]>> So what is the last value you are having here? Five.

[00:28:27]>> Five.

[00:28:28]>> So how you check this one? 30 minus 29.

[00:28:33]This last zero how you check mean 30 minus this one. How will become one?

[00:28:40]That's it. So total of this column is five. Total of this column is one.

[00:28:46]>> Yes ma'am.

[00:28:46]>> Total of this column is five. Total of this ideal column is one.

[00:28:51]>> So how you will write the uh statement here? Here you need to write the statement total elapsed time is equal to 30 hours. From where you are getting this 30 here last value of question two. Okay.

[00:29:15]>> The ideal time from A is five. The ideal time from B is 1. Ideal time. Total of A and B.

[00:29:30]Okay.

[00:29:33]>> Understood?

[00:29:35]>> Yes ma'am. I 1 hour that's two well person if they are asking problematic from unit number two they will ask the job sequencing only that's it okay now >> this question so you have understood now >> yes ma'am understood >> next question I will give you as a homework here also jobs they have given machine one machine two they have given okay you need to aggregate the segregate all What if what if they are giving machine one, machine two, machine three and they are giving the job. Here we have done only for machine one and machine two. No, if they are giving for machine one, two, three, what you will do? Means >> we need to segregate into the two things. For example, see here machine one is there, machine two is there, machine three is there, and they have given the jobs also. 1 2 3 four jobs is there. 1 2 4 6 7 8 9 10 14 12 11 16 like this they have given.

[00:30:42]>> Okay, >> there are three missions but only we should do it for the two missions only.

[00:30:47]Now only two missions will be there. How to segregate this three missions? How to compress this means? Give any two names.

[00:30:54]For example, I am giving like around S1 and S2. I am naming it as a S_sub_1 and S_sub_2. How you calculate S_sub_1 and S_sub_2? How many jobs you are having? 1 2 3 and four.

[00:31:11]How to calculate S1 and S2 means m1 + m2 you need to add, m_sub_2 + m3 you need to add. Then you'll get the s_sub_1 and s_ub_2. Clear?

[00:31:23]>> Yes, ma'am. Okay. For example, 7 + 1 is 8. 8 + 2 is 10. 9 + 4 is 13. 10 + 6 is >> 16. Like that. 16. Now, how you calculate?

[00:31:40]>> 7 + 14.

[00:31:42]>> 21.

[00:31:42]>> 21.

[00:31:45]>> 8 + 12 20 9 + 11 again 20 10 + 16 26.

[00:31:52]With the help of this you need to do the solution same like this.

[00:31:57]>> Okay. Means in this table in place of M1 and M2 S1 and S2 we should write one >> M1 M2 M3 you are having no when they are giving three machineries. Okay. Like this you need to compress that in the >> again two tables. Okay.

[00:32:15]>> Yes ma'am. Okay.

[00:32:17]>> Clear. Understood. Only this one you will do. Evening I will take you at 3:00 class. Okay.

[00:32:24]>> Okay ma'am.

[00:32:26]>> Will you join?

[00:32:31]>> What ma'am?

[00:32:32]>> Evening class you'll join.

[00:32:35]>> Uh yes ma'am I'll join >> like around 6:30.

[00:32:40]>> Yes ma'am. I'll join.

[00:32:42]>> Paka. 6:30 I'll schedule my classes.

[00:32:45]That's why.

[00:32:46]>> Yes ma'am. I'll join paka.

[00:32:49]>> Okay. Okay. Now you practice only this uh second unit. Okay.

[00:32:56]So in unit number three there are two topics of problematic we we need to discuss now. One is EOQ second one is ABC analysis. Okay. So these are the two problematic methods we need to discuss in unit number three. Okay. So both are easy and simple topics. Okay. So first we will complete EVOQ. EVOQ is a very basic question simple question and within 2 minutes or 3 minutes we can easily solve it. So EOQ stands for economic order quantity. Okay. EOQ formula is 2 AO divided by C under root.

[00:33:43]Okay. This is the formula for EOQ.

[00:33:47]Clear? So, A is nothing about assumption or annual consumption.

[00:33:55]Okay.

[00:33:59]C is nothing about carrying cost.

[00:34:05]O is nothing about ordering cost. Clear?

[00:34:09]So, simply give the data we need to substitute in the formula. So, that answer will be over. See here the question. Find EOQ from the following data. Average annual consumption is 30,000 units. Inventory carrying cost is 12%. Carrying cost always they will give it in a percentage. Once you remember that carrying cost always they will give in percentage. How much percentage they are giving? 12%.

[00:34:41]Cost of placing an order is 70. Okay.

[00:34:45]and ordering cost is 70. Cost per unit is 2. So how to solve the question means see here given that annual consumption is 30,000 units. Yes.

[00:35:04]Next. Carry cost how much percentage they have given? 12%. Okay. Ordering cost how much they have given? 70 per cost that is per unit how much they have given price per unit two okay this is the data they have given I have said no always carry cost they will give it in a percentage so we need to calculate C what is the price per unit 2 row into what is the percentage 12 so 2 into 12% how much it will be 2 into 12%. 0.24.

[00:35:46]So carrying cost is 0.24. Like this you need to calculate carrying cost in every question. After calculating it, what is the formula? EOQ is equal to under root 2 into a O. What is A? 30,000.

[00:36:07]What is O? 70 divided by what is C? 0.24.

[00:36:14]So 2 into 30,000 into 2 into 30,000 into 70 how much? It will be 42 lakhs divided by 0.24 under root. So divided by 0.24 24 if you're doing mean you are getting the value of 1 lakh 75 1 cr 75 lakh on the root what is the root value see here here you will find the root value just click on that what will be the answer you are getting 4183 unit soq is equal to 4183.3 units or 4183 is the answer understood everyone That's it. 12 mark question. This is >> clear.

[00:37:12]>> Yes ma'am.

[00:37:15]>> Next. See here. A factory uses two two 24,000 units of raw materials which cost 125 per unit. Placing each order is 25.

[00:37:28]Carrying cost is 6. So carrying cost percentage is 6%. Ordering cost O is 25.

[00:37:35]Cost per unit is 125. Annual consumption is 224,000.

[00:37:41]So we can find out the economic order quantity that is nothing about EOQ. You can find it. Now you have having you are having ordering cost you are having carrying cost. Everything you are having just you need to substitute in the formula. After that what they are asking how many orders are placed in a year.

[00:38:01]Sometimes they will ask the situation that how many orders placed in a year?

[00:38:08]How many orders placed in a year? How to calculate this one?

[00:38:18]So what is the formula? Annual consumption.

[00:38:24]Annual consumption divided by EVOQ if you are doing means you will get the how many orders placed in a year. So for this question what is the annual consumption 30,000 units what is evokq 4183 if you are dividing this with the with this two means 30,000 divided by 4183 if you are doing mean 7.171 is the how many order placed in a year so this is the answer like this you need to calculate it clear next if there asking computation of total inventory cost during the year.

[00:39:07]Right? That if they are asking this what is the formula? Annual ordering cost plus annual holding cost plus cost of material. So first you need to calculate annual ordering cost. Then you need to calculate annual holding cost. Then you need to calculate the purchase of cost material. Then after getting all these three just substitute in this formula you'll get the total inventory cost.

[00:39:32]What is the total inventory cost? Annual ordering cost plus annual holding cost plus cost of materials. First you need to calculate annual ordering cost. For that this is the formula for annual holding cost. For that this is the formula for cost of materials. This is the formula. After substituting every formula you'll get the values. After getting the values you need to substitute in the total inventory cost only these three we are learning in EOQ.

[00:40:04]One is economic order quantity. Second one is how many orders placed in a year.

[00:40:09]Third one is total inventory cost. These three methods we are discussing in the first point that is EOQ. Everyone understood?

[00:40:21]Yes.

[00:40:25]And doubt you any doubt.

[00:40:30]>> Understood.

[00:40:33]>> So in EOQ we have learned two other concepts also. How many orders placed in your total inventory cost that simple is this? If they are asking the problematic from unit number three first topic is EOQ only. Second is ABC analysis. How to do this ABC analysis means see here they have given a quantity ma'am in that EOQ more two questions are there they are not important >> what two questions >> more two questions are there in EQ >> in the book ma'am >> that that is I will give homework no ma'am this is all you need to do it >> okay all are important >> question homework >> okay >> all is important what I explain Then same thing this is homework problem after class I will send the pictures.

[00:41:23]Okay.

[00:41:24]>> Okay.

[00:41:25]You need to do homework. Here only they have asked total inventory cost and EOQ.

[00:41:30]But here they have asked EOQ to how many orders placed in a year.

[00:41:35]>> Same formula, same method of calculation but values will be different. Okay.

[00:41:39]>> Okay. Now >> next is ABC analysis. Okay.

[00:41:45]ABC analysis. How to calculate? This is also very easy problematic.

[00:41:51]A company uses 12 different items they are saying. So item 1 to item 12 they have given quantity they have given total unit cost also they have given.

[00:42:03]Okay after giving this simply what we need to do we need to calculate step number one. How to calculate step number one? Only one value will be added in the column. What is that total cost? Item they have given in the question. Annual demanded quantity they have given in the question. Unit cost also they have given in the question. In step number one what we need to calculate? We need to calculate total cost. How to calculate total cost? Simply multiply by 9,000 into 10 is 90,000. 300 into 750 is 225,000.

[00:42:40]5,400 + 2 5,400 into 210 is 11 lakh 34,000. Simply you need to do multiplication. That is the step number one. Whatever the data they have given no simply we need to do the multiplication of these two values and you need to write it in the column.

[00:43:00]Okay. Step number one understood everyone?

[00:43:06]>> Yes ma'am.

[00:43:08]In step number two, what we need to do mean we need to draw the three column.

[00:43:14]One is item number. Second one is a annual consumption value. Third one is cumulative.

[00:43:23]Annual consumption value that is AC.

[00:43:27]So here whatever the annual consumption value we have got. No that is total cost we have got. No. What is the highest value you are having? level that will be in.

[00:43:42]Okay.

[00:43:47]>> Yes.

[00:43:52]So first highest value you need to write it first. After 11 lakh highest value is 5 lakh 70. After that three lakh after that two lakhs after that like that from highest amount to lowest amount you need to write it in that. So what is the 114,000 item number is three. So that is also in that sequence order only you need to present it here. Clear according to the highest to lowest according to that item number only you need to clear it. Clear it till here. understood these two values.

[00:44:29]>> Yes ma'am.

[00:44:31]>> After that we need to calculate cumulative. How to calculate cumulative?

[00:44:35]What is the first value you are having here? 11 lakh 34,000 that will be same 11 lakh 34,000. 11 lakh 34,000 plus 5 lakh 70,000 is 17 lakh 4,000. 17 lakh 4,000 + 4 lakh 32,000 is 20 lakh 46,000.

[00:44:52]20 lakh 46,000 plus 250,000 is 22 lakh.

[00:44:57]So like that in zigzag way you need to calculate all the cumulative values.

[00:45:03]Clear understood step number one and step number two in ABC analysis.

[00:45:12]>> Yes ma'am understood. After that step number three in this step number three whatever the table it is there it is a fixed table for any problematic question of ABC analysis. So A B C what is the full form of ABC? Always better control.

[00:45:34]This is the full form of ABC. So for A it is 70%. For B it is 20%. per C it is 10%. This 70 20 and 10 whatever you are having that is fixed okay you should not change that A is always 70 B is always 20 C is always 10% clear then for category A you need to calculate the 70%. So how to calculate that means what is the total of annual consumption value 32 lakh 98,250 right for this you need to do the 70%.

[00:46:22]Clear? How to 70% means simply first you divide it 70 divide by 100. See 70% means how to calculate means 70 divided by 100 into total value that is 32 lakh 98,250 clear how to do this means 70 divided by 100 into 32 lakh 98,250 how much you're getting 23 lakh 8,775 23 23 lakh 8,775 for B. How to calculate for B? This how much you got? 23 lakh 8,775.

[00:47:13]No. Yes. How to check this means you need to check out here this 11 lakh 17 lakhs, 20 lakhs, 22.

[00:47:24]Here you will get 23 lakhs. Yes, in this in this Roma in the serial number seven you will get 23 lakh. So up to 1 2 3 4 5 this five items will be considered in a a category.

[00:47:43]Clear by like this only because we got the answer 23 8775 at what item you'll get 23 lakhs 8775 in this or no? So this will be all considered in A category. Next how to do B1 you need to add A + B. That means 70 + 20 it is 90,000. Yes 70 + 20 is 90,000. See 90%.

[00:48:14]So how to do that? 90% of 32 lakh 98,000 same 90 / 100 into 32 lakh 98, 250.

[00:48:27]Okay, understood the doubt you are having.

[00:48:32]Simply write you remembering the formula you will easily understand it. charging after charging clear understanding.

[00:48:48]>> Yes ma'am I understand.

[00:48:50]>> So how much you getting 29 lakh 68,425 here you will get 29 lakhs. No here you will get 29 lakhs. No in 30 lakhs you'll get 29 lakhs 68,425.

[00:49:03]So these three items will be considered in B category.

[00:49:08]Clear? Remaining all items will considered in C category. That's it.

[00:49:13]That you need to show it.

[00:49:16]Okay. So A and B you need to calculate.

[00:49:19]After that in step number four how you need to do it means what is the A category? Last number 25 lakh 36,000 divided by total value. This is the formula wise you need to understand into 100 you'll get 76.89%.

[00:49:34]Next what you need to do for B category what is the last value 30 lakh 16,250 divided by 32 lakhs 98 250 you'll get 91.45 simply what you need to do now 91 minus 76 you'll get the C value 14 56%.

[00:49:55]Like that you need to show in A category what are the items will be considered 3 level 4 10 7 3 level 4 10 7 in B category this three no it is 2 9 and 5 2 9 and 5 Next 61 8 12 61 812 that's you need to show it this table clear understanding or you having any doubt In in four steps we need to calculate ABC analysis. Okay. After writing this values next we need to plot the graph.

[00:50:34]So in a category how many items is there? 0 to 40. 40 to 60. 60 to 100. So 0 to 40 is A category. 40 to 65 is B category. 65 to 100 is C category. You need to draw the graph. This graph also will be same thing in every question like this only the structure of graph will be there for ABC analysis. Clear clear or you having any doubt?

[00:51:10]>> Clear.

[00:51:12]>> What about you Rohit?

[00:51:14]>> Clear ma'am.

[00:51:18]>> So that's it. ABC analysis is first one.

[00:51:21]Second one is evoke and number of placed items in your order that is inventory total cost that is only okay.

[00:51:33]Okay. Now yes. So my suggestion to you people is in second unit you are having problematic in third you are having problematic. In fourth and fifth also you are having problematic. First is completely theory. Okay. In management science minimum three problematics you need to attempt. So second unit problematic is easy. Third unit problematic is also easy. Fifth unit is also easy. Fourth unit is little bit difficult. So you can go with theory also in this in this also theory. In this also theory in this also theory in every unit one theory question along with that problematic I'll explain. In second also I'll give theory. In third also I'll give one explain theory. Fourth also one theory fifth also one theory you need to be perfect with problematic and you need to be perfect with one theory question whatever I have given in my note per okay so also problematic is little bit difficult it is little bit difficult not much difficult in understanding so equations will be there okay so penalty method will be there big method will be there normal method will be there so it will be very difficult to understand course unit. So you can easily skip this course unit if you are not understanding it.

[00:52:54]Okay. So one theory question one problematic question they will ask in the examination. So be perfect with the second, third and fifth unit problematic. Remaining fourth and first unit be perfect with theory and second third also you need to learn theory.

[00:53:10]What do you say? Is it fine?

[00:53:17]Yes ma'am.

[00:53:20]Because it will be very lengthy to understand. See, first they will give the equations. So after finding the equations, we need to put it in the LPP format. After LPP format, we need to present it in the simplex table. After presenting in the simplex table, we need to modify the values. After modifying the values, again we need to write the reodified values. See this much lengthy the question is there.

[00:53:44]Yes ma'am.

[00:53:49]>> In fourth unit we'll definitely get one theory question.

[00:53:53]>> Yeah one theory one problematic. In problematic we can discuss but you are having LPP method in simplex method LPP big method and in simplex again two method minimum and maximum and in big method also minimum and maximum. So that means 1 2 3 4 five six six kind of questions you need to perfect in fourth unit. So instead of remembering all that stuff just go with the theory. Be perfect with theory from unit number four. Second, third and fifth. Anyway you will with the problematic no.

[00:54:28]>> Yes ma'am.

[00:54:30]>> So that's it. Anyway I will preparing your note.

[00:54:34]Fourth I'll give one question only. So be perfect with that one question.

[00:54:38]Clear. Okay.

[00:54:45]>> He's not there right now.

[00:54:47]>> He was not there.

[00:54:49]>> No, sir.

[00:54:51]>> Okay. No problem. He was already listening.

[00:54:55]Okay. In unit number five, we are having 1 2 3. Okay. It is easy only. Unit number five is easy only.

[00:55:03]>> Okay.

[00:55:08]So now in marketing also one there ma'am in that problematic is also there ma'am in marketing in last unit. Yeah, in marketing what they are doing means one theory one problematic they are asking sometimes both the problematic they are asking sometimes both theory they are asking so we can't uh like give a option no so that's why what I'm saying in marketing research only one problematic method I'll explain that is easy only no problem >> in last unit >> yeah in last unit already I have explained part only is problematic >> yes >> okay Now tomorrow evening class I will take marketing research. Okay. Tomorrow I take this management science 50 problematic and theory also I'll explain at that time only. So that management tomorrow I'll complete it. So it will be your task to start your preparation.

[00:56:02]>> Yes ma'am.

[00:56:04]>> Marketing research problematic unit manage management science problematic and theory part 2 3 4 5 theory part.

[00:56:12]>> Yes ma'am. Today I'll prepare my notes.

[00:56:14]Okay.

[00:56:15]>> Okay. Ma'am can you send the important questions together? Problematic both we should do.

[00:56:23]>> Theory one theory you need to learn related to theory that is theory answer and remaining problematic this three problematic and Hungarian method is also problematic. So four problematic methods and one.

[00:56:39]>> Okay.

[00:56:39]>> Okay. It will be easy only not much difficult.

[00:56:44]Okay.

[00:56:51]>> Yes ma'am. The other boy is not there I think.

[00:57:21]that is not there already.

[00:57:29]>> So we having three methods. So first I will explain northwest corner method and you can do this in this also northwest corner method and method is most important. Hungarian method is little bit important. So what you do is prepare northwest corner method prepare east corner method and prepare Hungarian method look into that. Okay.

[00:57:51]Anyway, you will get clarity. Okay. So, >> yes ma'am. And that VM ma'am >> B is not much important.

[00:58:01]>> Okay.

[00:58:03]>> See they will ask they will give the data and they'll ask you to calculate IBFS. To calculate this IBFS out of three methods you can use any one method either northwest column method either square method either RAM method. So compared to these three methods any method and east square method or this method >> okay >> we can use any method >> any one method only either northwest or >> okay so how to do this northwest corner method means see here the table you're having Yes ma'am.

[00:58:50]>> See here what they have given supply they have given demand they have given 9 to three I will write it. So how to do this means?

[00:59:00]So P Q R S T and U. This is supply. Okay.

[00:59:08]>> P Q R S T and U.

[00:59:11]>> Ma'am what is the page number?

[00:59:15]157 rounds.

[00:59:17]>> Okay.

[00:59:19]>> Here you are having A, B, C and D. This is demand.

[00:59:24]Whatever that in the question same I have wrote like that only. Okay. What is the value we are having? 9 7 6 4 12 3 5 8 4 9 6 9 10 5 So whatever the data they are having no so same data we need to draw it here.

[00:59:56]Okay. What is the method name? Northwest corner method. Yes.

[01:00:02]>> Yes ma'am. Will they mention which method we should use or we can do any transportation problem? In transportation problem you can use northwest column method or column method or v specifically they not ask this method only you need to do they not ask northwest method only very easy.

[01:00:25]>> Okay. So northwest column mean what is the first value you are having? N over here. No.

[01:00:33]Yes.

[01:00:35]N. In column you are having five. In column wise you are having four. In row wise you are having the five. Yes. Here you are having five. Here you are having four. What is the least value? Five or four.

[01:00:49]>> Four.

[01:00:51]>> So four. Right. So here in the round column you need to write four. You need to deduct this column. You need to just deduct that column like like this.

[01:01:02]See what is the least value.

[01:01:06]So this column is deducted. Now only this values is there. So this column is next to this one.

[01:01:15]>> So here you what is the least value? One. That means row is detected.

[01:01:23]That mean this column is deducted. This row is deducted. Now next is >> here you are having three. Here also you are having three.

[01:01:39]>> So both it is >> also >> detected both will be detected because here also you having three. Here also you having three. Okay. So that's why in the round we are writing three. Okay.

[01:01:51]Next. Next is seven. Here you are having three. Here you are having six. Okay.

[01:01:59]What will be detected? Three will be deducted. So three is the least. So this column is deducted. Okay. Like this it will be there. Next is this.

[01:02:07]>> Yes.

[01:02:09]>> Two or six are two. That mean this column is deducted.

[01:02:15]Least value column or row will be. Okay.

[01:02:18]Now this value is over. Next like this it is having yes. So here you are having six. So one will be deducted.

[01:02:29]Next this column. So like that you need to deduct all columns whenever it will come last value. Okay.

[01:02:38]See here four. So this column will be deducted.

[01:02:42]Next two here also it will become two.

[01:02:44]So both will be deducted. That means all rows should get deducted. All columns should get deducted. Yes.

[01:02:53]>> Yes sir.

[01:02:56]>> So what is the formulas? How many we are having? 1 2 3 4 5 6 7 8 and 9.

[01:03:07]Yes.

[01:03:08]>> Yes.

[01:03:09]>> So total allocations is 9. How to do this n see here for 9 what is the value circle right so after the calculation so 9 into 4 plus here what you having 12 into 1 + 3 into 3 + 7 into 3 + 9 into 2 whatever we have calculated all we need to do multiplication we need to add 2 into 2 + 2 into 4 + 10 into Yes.

[01:03:45]>> After 96 12 here after multiply add. So total how much you getting?

[01:03:57]13.

[01:03:58]>> Yes.

[01:04:00]>> Yes ma'am.

[01:04:01]>> Ma'am can you show that once?

[01:04:05]>> Which one?

[01:04:07]Ma'am that deducting from the table that part.

[01:04:11]Yes sir.

[01:04:17]Okay. How to deduct ma'am?

[01:04:20]H >> can you explain? Can you explain again ma'am? How to deduct that from table?

[01:04:25]>> Yeah. I take a small table so that it will be easy to understand. See here S1, S2, S3 is there. Here you are having D1, D2, D3 is there. Okay. This is supply and this is demand. Okay. Like this it is there. So 8 5 6 15 10 12 3 9 10. So here you are having 120 80.

[01:04:52]Here you are having 150 80 50. So 150 + 50 is 200. 200 + 80 is 280. So 120 + 80 is 200. 200 + 80 is 280. So when you see a column when you see the row >> yes cell will become northwest format 120 is less >> 120 ma'am >> 120 so here I'm writing 120 in the table and here I'm deducting this so how much is left over 30 is left over here Now this row this column is rowed next >> 80 is least >> 31 >> this column is 80 - 30 is 50 >> yes >> next 50 so here I'm writing 50 >> and I'm deducting this 50 - 80 - 50 is >> 30 30 >> 30.

[01:06:10]Yes.

[01:06:12]>> Yes.

[01:06:13]>> For 10 it is having 50. Here also 50 that means column is detected row is detected over. Now what is the cell we are having here? 128. So 8 120 into 8 plus next 30 into 50 right?

[01:06:32]+ 50 into 10 + 30 into 9 plus next to this value right 50.

[01:06:43]>> Yes ma'am.

[01:06:45]>> 50 into 50. You need to add all these things. Whatever the final answer we will get that will IS clear.

[01:06:53]>> Okay ma'am.

[01:06:55]>> This is called northwest method is first cell.

[01:07:03]>> Yes ma'am.

[01:07:04]>> Okay. Okay. Next one you having least column method. How to take in a column?

[01:07:15]In a column, what is the least value of having 17, right?

[01:07:22]17 is the least value.

[01:07:24]>> Yes sir.

[01:07:25]>> 31 17 32. So here you are having six.

[01:07:30]What will be deducted? Six will be deducted. Okay. like this.

[01:07:38]>> Yes ma'am.

[01:07:43]>> Get the graph. Least column method means in a column we should not take first value in a column. What is the least value that you need to take it first?

[01:07:53]Same least whatever you have as a row or a column you need to deduct that. Same way of doing but you taking the least value in a column not if you're taking value if you're taking least method same everything.

[01:08:12]>> Okay.

[01:08:14]>> Yes.

[01:08:17]>> So see okay 21 16 5 and 3 is the least one.

[01:08:25]Yes.

[01:08:26]>> Yes ma'am.

[01:08:29]level which is level is you need to deduct this value. See here it is deducted.

[01:08:36]>> So here you write >> yes value 13 is least one. So four will be deducted.

[01:08:52]So 13 not this question only I'm writing here you are having yes >> D1 D2 D3 and supply okay the connection S1 S2 S3 demand Okay.

[01:09:28]>> 1 minute.

[01:09:33]>> 70.

[01:09:43]>> Very good.

[01:10:01]class.

[01:10:05]See this question we are doing in this problem. Okay.

[01:10:12]20 years 11 13 19 is 48 6 10 12 15 is also 48. Okay. Now least column method is nothing about in a in a row what is the least number having three. Yes.

[01:10:31]Here you having 15 level.

[01:10:40]What is the least one this column here? You write level 11.

[01:10:49]Okay. So 15 - 11 is four.

[01:10:53]>> Four.

[01:10:54]>> Next in this one. What is the least one?

[01:10:57]13 is the least one.

[01:10:58]>> Here you having 13. Here you having four. 13 >> four.

[01:11:05]So here you get this column. So 13 - 4 is 9.

[01:11:11]>> Okay.

[01:11:13]>> Yes ma'am.

[01:11:15]>> Yes ma'am.

[01:11:18]>> Next one. Again in this row what is the least one? 17 18. 14 is the least one.

[01:11:23]No.

[01:11:25]>> Yes ma'am.

[01:11:25]>> 9 12 least one with 9 is the least one.

[01:11:29]So here I'm adding 9 and detecting this.

[01:11:31]So 12 is three. Next here is 18.

[01:11:42]So 19 - 3 is >> 16.

[01:11:52]>> Yes ma'am.

[01:11:55]>> Next one. So how you do this? So 11 into 3 + 9 into 14 + 14 into 13 + 3 into 18.

[01:12:07]So whatever the things we have got 1 2 3 4 four we have got that four you need to multiply you need to add it that is the answer column method you need to take the each column what the least value >> yes so column method and less common method you do it and Hungarian method is not much important but I'll explain roughly Hungarian is nothing.

[01:12:47]>> Yes.

[01:12:57]Hungarian question the no problem or transportation method problematic only rather than okay transportation problem. Okay. Or else what do you say?

[01:13:30]>> Transportation problem. In transportation problem we have discussed northwest corner method and east corner method. This two problem.

[01:13:43]>> Okay.

[01:13:43]>> Okay. So here what we do is nothing about assignment problem in each row and each column at least one job should be there. So in a column what is the least value? 8 in 79 level 8 is the least value. So in the place of 8 we need to keep zero. Next in the second one 30 28 4 and 26 4 is the least value.

[01:14:11]So that it is zero. Yes. Now that's why we zero value zero. Okay. So like that zero in four column only. So that means you're having two.

[01:14:41]>> So we need to do the column deduction.

[01:14:44]How to do the column deduction? Now check out the column. What is the least value in the column? Again eight least value.

[01:14:50]>> Yes ma'am.

[01:14:52]>> So in the place of the place of keep it zero. Now here in the third column is the least value. So here only in the fourth one >> in each row and each column at least one job you having in A you having first job in B you are having third job in C you are having second job in D you are having fourth job yes >> yes ma'am >> A first job B third job D second job D fourth job like that in every column and in every Oh, you at least you need to have one job. One job is nothing at least one zero is double again to do the column deduction again reduction, column reduction, row deduction, column reduction and it will continue till end. Okay. Yes ma'am.

[01:15:49]>> So that's it. So be perfect with transportation problem in unit number five that is northwest corner method east and part that's >> okay related to here what is mean by when we are going into any to collect from your college we will form a fuel line why we to get to save the time. Yes, this diagram is only one answer that is theory conceptual of theory in the examination finding theory in the question or Q in the question. This is the only answer.

[01:16:41]>> Okay ma'am. Yes. Now just make sure not down in the management what we have discussed from unit number one we are completely clear in unit number two we have discussed job sequencing yes >> number two problematic unit number four completely clearing unit number five is transportation problem that is NWCR method and VA method And along with the student here this part only be perfect. And from unit number four what is the theory answer?

[01:17:22]You will learn only one answer. No that is called LP answer. Now page number 120 question number 16.

[01:17:33]Okay.

[01:17:35]>> Yes.

[01:17:38]Question number 16 not that question in unit number four what question you will read the theory means that is operations research related answer you need to learn what is the answer for that you are having means managerial operations like two to three questions if you are having you need to merge all that like for example you need to learn the operations researcher From first I have explained operation such the same topic you are having for also.

[01:18:13]So operation operation three meaning operation research definition and side points are advantages together you need to learn advantages five disadvantages five total 10 points.

[01:18:30]Yes. Okay.

[01:18:31]>> Yes. Yes ma'am. Ma'am once can you send this questions in WhatsApp? Yeah, I'll send it after the class. I'll send it.

[01:18:38]So, unit four only one answer related to the operations research. Unit five only one theory answer related to theory.

[01:18:45]Unit three is problematic. Unit two is also problematic. And in unit number two also just look into this theory question. What is that question? Plan layout.

[01:18:56]Sometimes they're asking theory also.

[01:18:58]What is the topic? Only one answer only.

[01:19:02]Now you can easily learn.

[01:19:04]Okay.

[01:19:16]>> Okay. Okay.

[01:19:20]>> I'll send you the question. So except the unit three remaining first unit second unit four fifth to four questions four theory questions you are learning and unit two unit three unit five problematic you are learning okay you should have the clarity what you are learning okay after the class I will unit theory theory all theory questions I will send the pictures just make sure you write it in your notes Okay.

[01:19:52]>> Okay.
