Cooper’s Copy Shop is considering two different processes for completing copying jobs brought in by customers. Process A uses one person to setup the job and do the copying. 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 copying. Setup on one job can be done while copying is being completed on another but copying must be completed on a job before the copying machine can start copying 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 copying. In either case, assume an 8 hour day, 5 days per week, 250 days per year.
(a) Assuming ideal conditions, what is the design capacity of Process B?
(b) How long would it take to process 200 jobs using Process A (assume only one worker and one machine)?
(c) How long would it take to process 200 jobs using Process B (assume only one “production line”)?
(d) If Cooper is primarily interested in providing low cost to customers, which Process should he put in place?
(e) If Cooper is primarily interested in providing quick service to customers, which Process should he put in place?
