When a manager considers the effect of changes in an LP model's coefficients he/she is performing a. a random analysis. b. a coefficient analysis. c. a sensitivity analysis. d. a qualitative analysis. Which type of spreadsheet cell represents the objective function in an LP model? a. Objective cell b. Changing variable cell c. Constraint cell d. Constant cell 3. A binding less than or equal to constraint in a maximization problem means a. that all of the resource represented by the constraint is consumed in the solution. b. it is not a constraint that the level curve contacts. c. another constraint is limiting the solution. d. the requirement for the constraint has been exceeded. 4. The solution to an LP problem is degenerate if a. the right-hand sides of any of the constraints have an allowable increase or allowable decrease of zero. b. the shadow prices of any of the constraints have an allowable increase or allowable decrease of infinity. c. the objective coefficients of the variables have an allowable increase or allowable decrease of zero. d. the shadow prices of any of the constraints have an allowable increase or allowable decrease of zero. 5. The allowable decrease for a changing cell (decision variable) is a. the amount by which the constraint coefficient can decrease without changing final optimal solution. b, an indication of how many more units to produce to maximize profits. c. the amount by which objective function coefficient can decrease without changing the final optimal solution. d. an indication of how much to charge to get the optimal solution. 6. Binding constraints have a. zero slack. b. negative slack. c. positive slack. d. surplus resources
