Fourteen jobs must be assigned to one of three identical machines. The goal is to minimize the total time needed to complete all 14 jobs. The machine capacities and times needed for the jobs are given in file P08_25.xlsx. For example, job 8 requires 3 units of capacity on a machine for 2 hours. At any given time, a machine has 5 units of capacity. How should you assign the jobs to machines to ensure the earliest possible completion of all jobs?
