Post-optimality Analysis (or Sensitivity Analysis) is concerned with the propagation of uncertainties in mathe- matical models It belongs to a broader area of Perturbation Analysis that defines the largest sensitivity r[3] e- gion and its main goal is to assess the influence of parameter changes on the state of the system -opti[4]-

What is sensitivity analysis?

Sensitivity Analysis basically formulates a range of values that the coefficients of the objective function can take that will not have an effect on the optimal solution. However even though the optimal solution is not affected, the optimal objective function value will change as the coefficient increases or decreases.

How do you find a range of optimality?

Graphically, the limits of a range of optimality are found by changing the slope of the objective function line within the limits of the slopes of the binding constraint lines. The slope of an objective function line, Max c1x1+ c2x2, is -c1/c2, and the slope of a constraint, a1x1+ a2x2= b, is -a1/a2. Example 1 Range of Optimality for c1

Is the optimal value the same in both cases?

In both cases, the optimal value is the same, which is always going to be the case. how they are related to each other. For example, the shadow prices in the maximization model represent the solution values in the minimization model. The information
