- 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?The normal time for a work cycle in a worker–machine system is 6.27 min.

The PFD allowance factor used to set the standard was 13%. During a particular 8-hour shift of interest, it is known that the worker lost a total of 53 min due to personal time, rest breaks, and delays. On that same day, the worker completed 214 work units. Determine (a) the number of standard hours accomplished, (b) worker efficiency, and (c) the worker’s performance level expressed as a percentage.The first day of basic training at the Air Force Academy is quite a sight, with 1500 cadets being processed in. This involves getting haircuts, uniforms, room assignments, and a mountain of paperwork. At the Uniform Fitting station, the worker takes the measurements on the cadet (which takes about 2 minutes), then retrieves shirts, pants and hats in his/her size (which takes about 2 minutes), waits for the cadet to try on the pants (which takes about 1 minute) and then marks the pants for hemming (which takes about 1 minute). The in-processing takes place from 8 AM to 5 PM with an hour off for lunch (8 hours). __________2a. How many cadets can a single worker fit for uniforms on that hectic day? __________2b. How many workers would be needed to fit 1601 cadets in one day, if everyone works at full capacity?

- Supervisor Tom Choi at Tempe Equipment Companyis concerned that material is not arriving as promptly as needed atwork cells. A new kanban system has been insta lled, but there seemsto be some delay in getting the material moved to the work cells sothat the job can begin promptly. Choi is interested in determininghow much delay there is on the part of his highly paid machinists.Ideally, the delay would be close to zero. He has asked his assistantto determine the delay factor among his 10 work cells. The assistantcollects the data on a random basis over the next 2 weeks anddetermines that of the 1,200 observations, 105 were made while theoperators were waiting for materials. Use a 95% confidence leveland a ±3% acceptable error. What report does he give to Choi?A time study analyst timed an assembly operation for 30 cycles, and then computed the average time per cycle, which was 18.75 minutes. The analyst assigned a performance rating of .96, and decided that an appropriate allowance was 15 percent. Assume the allowance factor is based on the workday. Determine the following: the observed time (OT), the normal time (NT), and the standard time (ST).What are the trade-offs in the following?A.
