Sensitivity analysis and duality
WebThe sensitivity report from the excel solver shows that the shadow prices are 8, 0 and 6 for the three resources. The worth of the resources are 60 x 8 + 80 x 0 + 80 X 6 = 960 which is equal to the revenue. It is observed that the shadow price of resource 2 is zero. This is because this resource is not fully consumed. Webproposes a general approach to sensitivity analysis that applies to both continuous and discrete problems. In the continuous case, particularly in linear programming, sensitivity …

INTRODUCTION Formally, sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be apportioned to different sources ...
WebSENSITIVITY ANALYSIS •Simultaneous Changes - The range analysis for objective function coefficients and the constraint right-hand sides is only applicable for changes in a single coefficient. •Changes in Constraint Coefficients – Classical sensitivity analysis provides no information about changes resulting from a change in a coefficient of a Webto operate a system. The study of duality is hence the study of a parameterized family of mathematical programming instances and is closely related to parametric programming and sensitivity analysis. More formally, duality theory can be thought of as the study of the so-called value function, which is a function
