Linear programm ing helps operations managers make decisions necessary to make effective use of resources such as machinery , labor, money, time, and raw materials. True (Introducti on, easy) 2. One requireme nt of a linear programm ing problem is that the objective function must be expressed as a linear equation. True (Introducti on, easy) 3. A common form of the productmix linear programming seeks to find that combination of products and the quantity of each that maximizes profit in the presence of limited resources. True (Formulating linear programming problems, moderate) 4. Linear programming is an appropriate problemsolving technique for decisions that have no alternative courses of action. False (Requirements of a linear programming problem, easy) 5. In linear programming, a statement such as "maximize contribution" becomes an objective function when the problem is formulated. True (Formulating linear programming problems, moderate) 6. Constraints are needed to solve linear programming problems by hand, but not by computer. False (Graphical solution to a linear programming problem, easy) {AACSB: Use of IT} 7. In terms of linear programming, the fact that the solution is infeasible implies that the "profit" can increase without limit. False (Graphical solution to a linear programming problem, moderate) 8. The region that satisfies all of the constraints in graphical linear programming is called the region of optimality. False (Graphical solution to a linear programming problem, moderate) 9. Solving a linear programming problem with the isoprofit line solution method requires that we move the isoprofit line to each corner of the feasible region until the optimum is identified. False (Graphical solution to a linear programming problem, moderate) 10. The optimal solution to a linear programming problem is within the feasible region. True (Graphical solution to a linear programming problem, moderate) 11. For a linear programming problem with the constraints 2X + 4Y 100 and 1X + 8Y 100, two of its corner points are (0, 0) and (0, 25). False (Graphical solution to a linear programming problem, moderate) {AACSB: Analytic Skills} 5 12. In linear programming, if there are three constraints, each representing a resource that can be used up, the optimal solution must use up all of each of the three resources. False (Graphical solution to a linear programming problem, moderate) 13. The region that satisfies the constraint 4X + 15Z 1000 includes the origin of the graph. False (Graphical solution to a linear programming problem, easy) {AACSB: Analytic Skills} 14. The optimal solution of a linear programming problem that consists of two variables and six constraints will probably not satisfy all six constraints precisely....
