A linear programming computer package is needed. Frandec Company manufactures, assembles, and rebullds material-handiling equipment used in warehouses and distribution centers. One product, called a motor, two supports, and a metal strap. Frandec's production schedule calls for 5,500 Liftmasters to be made next month. Frandec purchases the moti straps may be either manufactured by the company or purchased from an outside supplier. Manufacturing and purchase costs per unit are shown. Three departments are involved in the production of these components. The time (in minutes per unit) required to process each component in each dep departments are as follows (a) Formulate and solve a linear programming model for this make-or-buy application.
