scientific approach to managerial problemsolving under such other names as systems analysis‚ cost–benefit analysis‚ and cost-effectiveness analysis. We will adhere to management science throughout this book. Mathematical programming‚ and especially linear programming‚ is one of the best developed and most used branches of management science. It concerns the optimum allocation of limited resources among competing activities‚ under a set of constraints imposed by the nature of the problem being studied

estimate the following forms of demand function: i) Y=a + b X (Linear) Y= quantity of eggs consumed‚ a = constant b = intercept X= per capita disposable income Here we have used single equation regression model‚ which carries two variables one is dependent and another one independent variable. The form equation is like this: i) Y= 3.0085 + 0.0619 X R2 = 0.8569 (13.5301) (2.76) The linear function gave a ‘consistently better fit to the data. From the

performance of the system. Techniques and tools of operation research: Linear programming: You can use linear programming to find a solution for optimising a given objective. The objective may be to maximize profit or to minimize cost. Inventory control methods: The production‚ purchasing‚ and material managers are always confronted with questions‚ such as when To buy‚ and how much to keep in stock. Goal programming: In linear programming ‚ you take a single objective function and consider all other
