Figure 4. changes in the coefficients of the objective function changes in the right-hand side value of a constraint Sensitivity Analysis Sensitivity analysis (or post-optimality analysis) is used to determine how the optimal solution is affected by changes, within specified ranges, in: the objective function coefficients Do US public school students have a First Amendment right to be able to perform sacred music?
