Eight jobs need to be completed. Each job can be completed on any of six machines, and each machine can complete any number of jobs. If a machine is assigned to at least one job, the setup time listed in the file P06_62.xlsx is required. (All times are in hours.) The time required for each machine to complete each job (excluding the setup time) is also listed in the same file. How should the jobs be assigned to machines to minimize the sum of setup times and job completion times?
