Question

Reconsider the model of Prob. 7.1-1. You are now to conduct sensitivity analysis by independently investigating each of the following six changes in the original model. For each change, use the sensitivity analysis procedure to revise the given final set of equations (in tableau form) and convert it to proper form from Gaussian elimination. Then test this solution for feasibility and for optimality. (Do not reoptimize.)
(a) Change the right-hand side of constraint 1 to b1 = 10.
(b) Change the right-hand side of constraint 2 to b2 = 10.
(c) Change the coefficient of x2 in the objective function to c2 = 3.
(d) Change the coefficient of x3 in the objective function to c3 = 2.
(e) Change the coefficient of x2 in constraint 2 to a22 = 2.
(f) Change the coefficient of x1 in constraint 1 to a11 = 8.
