2 Today’s Learning Goals Sensitivity Analysis Changes in the objective function Coefficient s Changes in right-hand side values
3 Sensitivity Analysis Optimal solutions to LP problems thus far have been found under what are called deterministic deterministic assumptions. assumptions. This means that we assume complete certainty in the data and relationships of a problem. But in the real world, conditions are dynamic and changing. We can analyze how sensitive sensitive a deterministic solution is to changes in the assumptions of the model. This is called sensitivity analysis sensitivity analysis , postoptimality postoptimality analysis analysis , parametric programming parametric programming , or optimality optimality analysis. analysis.

4 Sensitivity Analysis Sensitivity analysis often involves a series of what-if? questions concerning in the coefficients of a LP problem How will change in a coefficient of the objective function affect the optimal solution? How will a change in the right-hand-side value for a constraint affect the optimal solution? After a problem has been solved, we determine a range of changes in problem parameters that will not affect the optimal solution or change the variables in the solution.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
