SENSITIVITY ANALYSIS The solution obtained by simplex or graphical method of LP is based on deterministic assumptions i.e. we assume complete certainty in the data and the relationships of a problem namely prices are fixed‚ resources known‚ time needed to produce a unit exactly etc. However in the real world‚ conditions are seldom static i.e. they are dynamic. How can such discrepancy be handled? For example if a firm realizes that profit per unit is not Rs 5 as estimated but instead closer

Linear Programming Notes VII Sensitivity Analysis 1 Introduction When you use a mathematical model to describe reality you must make approximations. The world is more complicated than the kinds of optimization problems that we are able to solve. Linearity assumptions usually are significant approximations. Another important approximation comes because you cannot be sure of the data that you put into the model. Your knowledge of the relevant technology may be imprecise‚ forcing you to approximate

Sensitivity analysis is a technique that indicates exactly how much a project’s profitability (NPV or IRR) will change in response to a given change in a single input variable‚ other things held constant. Sensitivity analysis begins with a base case developed using expected values (in the statistical sense) for all uncertain variables. Then‚ each uncertain variable is usually changed by a fixed percentage amount above and below its expected value‚ holding all other variables constant at their expected

Sensitivity Analysis The variables used to develop the table‚ including sales price‚ variable costs‚ unit sales‚ and the unit growth rate‚ are all most likely‚ or base-case‚ values‚ and the resulting $25‚517 NPV shown in Part 5 is called the base-case NPV. Now we ask a series of "what if" questions: "What if unit sales falls 30 percent below the most likely level?" In our sensitivity analysis we hold the other variables at their base case levels and then examine the situation when the key variables
