Exercise 19

Haller Manufacturing has two production facilities that manufacture baseball gloves. Production costs at the two facilities differ because of varying labor rates, local property taxes, types equipment, capacity, and so on. The Dayton plant has weekly costs that can be, be expressed as a function of the number of gloves produced:
where X is the weekly production volume in thousands of units and TCD(X) is the cost in thousands of dollars. The Hamilton plant's weekly production costs are given by
where Y is the weekly production volume in thousands of units and TCH(Y) is the cost in thousands of dollars. Heller Manufacturing would like to produce 8000 gloves per week at the lowest possible cost.
a. Formulate a mathematical model that can be used to determine the optimal number of gloves to produce each week at each facility.
b. Use LINGO or Excel Solver to find the solution to your mathematical model to determine the optimal number of gloves to produce at each facility.
