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. 3. Assuming ideal conditions, what is the maximum capacity of process B? 4. How long would it take to process 200 jobs using process A (assume only one worker and one machine)? 5. If Rocky’s is primarily…

The normal time for a work cycle in a worker-machine system is 6.0 min. For setting the standard time, the PFD allowance factor is 15%, and the machine allowance factor is 20%. The work cycle includes manual elements totaling a normal time of 5.5 min, all but 0.75 min of which are performed as internal elements. Determine (a) the daily output at standard performance. (b) During an 8-hour shift, the worker lost 20 min due to personal time, rest breaks, and delays, and she produced 80 pieces. What was the worker’s pace on the operator-controlled portion of the shift?
