03 Sensitivity Analysis For Lp Changing One Objective Coefficient Outside The Range Of Optimality

Chapter 4 Lp Sensitivity Analysis Pdf This video demonstrates what happens to the optimal solution and the optimal objective function value in linear programming (lp) problems when we change one. Explore sensitivity analysis and post optimality in linear programming. understand how changes in objective function coefficients, constraints, and resources impact optimal solutions.

Sensitivity Analysis Of An Lp Model Determining The Range Of Unit Step one: remember the binding and non binding constraints that were found earlier in the problem. you can state that the shadow price of a non binding constraint is 0 (there is nothing to solve). If you want to know the range over which each objective coefficient can vary without changing the variables in the basis, you can use the rangeprice option in the proc lp statement. In this section we study general questions involving the sensitivity of the solution to an lp under changes to its input data. as it turns out lp solutions can be extremely sensitive to such changes and this has very important practical consequences for the use of lp technology in applications. Let us consider how changes in the objective function coefficients might affect the optimal solution. the range of optimality for each coefficient provides the range of values over which the current solution will remain optimal.

Let us consider how changes in the objective function coefficients might affect the optimal solution. the range of optimality for each coefficient provides the range of values over which the current solution will remain optimal. When two coefficients are varied simultaneously, the analysis is much more complex because the “range” is described by a 2 dimensional polyhedron rather than an interval on the real line. In general, the rc value of any non basic variable is the amount the objective coefficient of that variable would have to change, ceteris paribus, in order for it to become a basic variable at optimality. From the above collection of simultaneous inequalities, we can easily figure out how much the coefficient of x can change by in the objective, while leaving the optimum unchanged, if all the other coefficients remain unchanged. The document presents a case study on sensitivity analysis in linear programming using the beaver creek pottery company and examples of producing tables, chairs, and running shoes.
