Capacity Problems
|
Rocky’s Pre-Cast Shop is considering two different processes for completing Pre-Cast jobs. Process A uses one person to setup the job and do the pre-casting. If this approach is used, an experienced person can complete an average of 20 jobs per day. Process B uses two people. One person does the setup and the second person does the actual pre-casting. Setup on one job can be done while pre-casting is being completed on another but pre-casting must be completed on a job before the pre-cast machine can start processing the next. After some practice, this second process can be completed with a standard time of 10 minutes for setup and 15 minutes for actual pre-casting. In either case, assume an 8-hour day, 5 days per week, 250 days per year.
