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

time periods. The two stories both have their pros and cons of the society that is being portrayed in the text. The pros of the societies in the stories are found more in “The Voter” than in “Tribal Scars”. This mainly has to do with the fact that the society in Achebe’s story was based in a more recent time which allowed for the society to be more far and democratic and this would be the most noticeable pro throughout the stories. Another pro for “The Voter” would be that almost all of the
