[00:00:01]Welcome to tutor flex. [music] Hi teachers operations research question.

[00:00:29]Okay. First operations research.

[00:00:42]Okay. So first operations research world war.

[00:00:57]Okay. So So worldcient Scientific approach, air military resource.

[00:01:39]First main reason initial stages operations research operation analysis operations evolution system analysis. Okay.

[00:02:21]expand. Okay. So, expandation.

[00:02:46]Okay.

[00:02:49]overment and fin.

[00:03:00]Okay. So simplex linear programming. Okay.

[00:03:08]for 1947.

[00:03:19]Okay.

[00:03:27]First linear programming.

[00:03:33]Next dynamic programming inventory.

[00:03:38]Major techniques. Okay.

[00:03:42]Defense, industry, transport, business management, planning and decision making.

[00:03:53][snorts] Okay. So, basic definition or is the application of probability, linear programming, queuing theory, etc. Okay. To the problems of war and industry. So application of probability linear programming war is the art of winning wars without actually fighting.

[00:04:39]Okay. Next. key features.

[00:04:43]First approach decision So next one optimum use of resource optimization. Okay. Optimization.

[00:05:21]Optimization.

[00:05:24]Optimum solutions mean first initial stage 10%.

[00:05:51]50% off.

[00:05:55]Buy one get one offer.

[00:06:12]Okay.

[00:06:23]50 packag packet yellow buy 1 get one 50% effective.

[00:07:05]So multiple solutions optimum main. Okay. Next objective of scientific basis optimum solution best possible solution.

[00:07:41]So operations formulation of the problem.

[00:07:57]Okay.

[00:07:59]So, first rupees.

[00:08:17]5.

[00:08:31]So first 3x + 5 y 4 x + 6 Okay.

[00:09:02]Okay.

[00:09:09]What are the objectives?

[00:09:18]programming problem investment or expense in which Okay.

[00:09:48]Okay.

[00:09:52]for maximization.

[00:10:10]Okay. So objectives next uncontrollable variables.

[00:10:37]for uncontrollable variables.

[00:10:55]Okay. So formulation firstaliable.

[00:11:25]Okay.

[00:11:34][snorts] Okay. Next mod, analyt Okay. So option A.

[00:12:19]Okay.

[00:12:30]Optimal solution.

[00:12:47]Maximum value 500 optimal solution. So questional solution maximal solution.

[00:13:10]Okay. Next result simpocation problem.

[00:13:51]Okay.

[00:13:59]500 limited resource best.

[00:14:17]Okay. for allocation problem, maximize profit. Okay. Cost expense or investment. So cost profit or return max.

[00:15:15]Next allocation problem three types linear programming problem. Next assignment problem. Third one transportation problem. So first linear programming problem first 2x + 5 y + 3 something.

[00:15:42]Okay.

[00:15:46]linear equation.

[00:15:48]So linear programming simple programming problem.

[00:16:31]Next video more than enough book.

[00:16:57]Okay.

[00:16:59]problem download.

[00:17:21]Okay, next class. Thank you.
