What Is a Sensitivity Analysis? Definition and Examples

WebJun 23, 2012 · There’s something else quite interesting about duality: It gives directly a sensitivity analysis. Consider our primal problems. It’d be interesting to know how much more I could get, had my knapsack been larger or my body stronger. This looks like a difficult question in the primal program, but it’s very obvious in the dual program.

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. finger butter cookies
