Choose the correct answer by circling the letter T for TRUE or F for FALSE. T F The feasible region is the set of all points that satisfy at least one constraint. 2 T F In two-dimensional problems, the intersection of any two constraints gives an extreme point of the feasible region. T F An optimal solution uses up all of the limited resources available. T F Infeasibilty, as opposed to unboundedness, has nothing to do with the objective function. T F Consider any point on the boundary of the feasible region. Such point satisfies all the constraints. T F An Active inequality constraint has zero slack or surplus, which means that the optimal solution satisfies the constraint with equality. T F Sensitivity analysis greatly increases the possibility that a model can be useful to management. T F Changing the RHS of a constraint changes its slope. T F Adding constraints to a model may help i.e., improve the OV. T F Positive slack variables at optimality indicate redundant constraint. All activities on the critical path have their latest finish time equal to their earliest start time. A constraint with positive optimal slack will always have an infinite allowable increase for the RHS . To solve a Max transportation problem you terminate when all the unused routes have negative marginal values. The stepping stone method requires a feasible solution as a starting point. In a MAX LP model, if the objective function cj for a basic variable increased by less than the allowable increase only the objective function value will change.
