Problema 1 (extraído del libro de texto, problema 17, página 504) A product can be produced on four different machines. Each machine has a fixed setup cost, variable production costs per-unit-processed, and a production capacity given in Table 15. A total of 2,000 units of the product must be produced. Formulate an IP whose solution will tell us how to minimize total costs.

Problema 2 (extraído del libro de texto, problema 23, página 505) At a machine tool plant, five jobs must be completed each day. The time it takes to do each job depends on the machine used to do the job. If a machine is used at all, there is a setup time required. The relevant times are given in Table 20. The company’s goal is to minimize the sum of the setup and machine operation times needed to complete all jobs. Formulate and solve (with LINDO, LINGO, or Excel Solver) an IP whose solution will do this. Solucion: Variables de decision: Funcion objetivo: Min Z= S.A. 5
