A fleet repair center resets its computerizeddiagnostic system after every 15 trucks to helpensure there are limited major downtimes fromsystem failure. The reset takes 22 minutes onaverage with aCV of 0.3. Each trucks diagnosis takes 28minutes on average with a CV of 1.75 notconsidering the resets.1. What is the effective process time and its CV?2. If the reset system is not used, failures willoccur after 57 hours on average with anaverage repair time of 3 hours. The CV of repairtime is 0.9. What is the effective process timeand its CV? Is the maintenance systembeneficial if it prevents breakdowns? Justconsider effective processing time parameters.3. The maintenance program costs $10,000annually. The average profit per carfrom the diagnostic service is $75. Assume theservice center operates 250 days per year, 10hours per day. Is the maintenance programeconomically beneficial? What assumptions areneeded?

A manufacturer of household kettles subjected 50 kettles to 10 000 hours of testing. Test results for the 50 kettles show that there were two failures at 3500 hours, two failures at 4800 hours, one failure at 8600 hours, and two more failures at 9000 hours. 4.1.1 Calculate the failure rate percentage (FR %).4.1.2 Calculate the number of failures per unit-hour (FR N).4.1.3 Calculate the MTBF at this point in testing.
Assume Bristol-Myers Squibb is faced with one source of business risk as worker's injury.

Part X requires operation A and operation B on the SAME MACHINE in sequence (First Operation A then operation B are performed on the same machine). Assume the company will be operating five days per week 8 hours per day. The following information is known: Operation Standard Time Efficiency Reliability Defect Rate A 3 min 95% 95% 2% В 5 min 95% 90% 5% OA = 18 Og = 1000 parts/week Operation A Operation B PA=2% Pg=5% a. In order to produce 1000 units of X in a week units X is scheduled weekly for Operation B (due to 5% scrap ratio) _units X is scheduled weekly for Operation A (due to 2% scrap ratio) b. Based on your answer in part a, find the number of machines required to produce 1000 units of X per week. The total time required to perform Operation B = minutes per week The total time required to perform Operation A =. minutes per week H= Available Time in a week = minutes /week Thus FA = FB = Since both of the operations A and B are performed on the same machine machines are required
