Question
Problem 1 The management of MACU Corporation is trying to determine the amount of each of two products to produce over the coming planning period. The following information concerns labor availability, labor utilization, and product profitability:
Product (hours/unit)
1 2
What are the optimal (maximum profit) production quantities for the company?
a. What type/s of model/s should be used to solve the problem and why would you use that model/s?
b. Develop a model of the MACU Corporation problem. Solve the model to determine the optimal product quantities of products 1 and 2.
c. In computing the profit contribution per unit, management did not deduct labor costs because they are considered fixed for the upcoming planning period. However, suppose that overtime can be scheduled in some of the departments. Which department would you recommend scheduling for overtime? How much would you be willing to pay per hour of overtime in each department?
d. Suppose that 10, 6, and 8 hours of overtime may be scheduled in departments A, B, and C respectively. The cost per hour of overtime is $18 in department A, $22.50 in department B, and $12 in department C. Formulate a model that can be used to determine the optimal production quantities if overtime is made available. What are the optimal product quantities, and what is the revised total contribution to profit? How much overtime do you recommend using in each department? What is the increase in the total contribution to profit if overtime is used?

a.) Linear programming model is used to slove this problem. because Linear programming is a widely used model type that can solve decision problems with thousands of variables. The feasible decisions are compared using an objective function that depends on the decision variables. For a linear program the objective function and constraints are required to be linearly related to the variables of the problem.All LP problems are seek to maximize or minimize some function, usually profit or cost.
