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

1. How sensitive is Db to s? To N? Db is the particular measure of species richness and it decreases when s (the number of different species) decreases. Db decreases when N (the number of individuals) increases. 2. How s and N affect the Simpson Index? Simpson Index is a measure of diversity which takes into account the number of species present‚ as well as the relative abundance of each species. In this case‚ a few rare species (s) with only a few representatives (N) will not affect the diversity

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

as the discount rate in net present value (NPV) project appraisal techniques.1 The weighted-average cost of capital (WACC) represents the overall cost of capital for a company‚ including the costs of equity and cost of debt‚ weighted according to the proportion of each source of finance within the business. In easy words WACC measures a company’s cost to borrow money. The WACC equation is the cost of each capital component multiplied by its proportional weight and then summing: Where: Re
