1. Mention the differences between assembly chart and operations process chart. 2. What would be the objective in designing each facility below: A Bank; A Hospital; A Production line; A Clinic 3. A part requires two machining operations (I and II) on a milling machine. 8000 units are to be produced per month (20 working days). The factory operates 8 hours per day. The following information is known. ine mumng macnine requires tool changes arter every lot or suv parts. Tool change time is 25 minutes. How many milling machines are needed? 4. During an 8-hour shift, 2000 non-defective parts are desired from an operation. The standard time of operation is 10 minutes. Because the operator is inexperienced, the actual time is 25% more than the standard time on the average. Also 10% of parts produced are scrapped. Each machine is expected to be available only 7 hours per shift. Determine the number of machines required for this operation. 5. Part A is produced on machines 1 and 2, and 3. Part B is produced on machines 4 , 5, and 6. Part A and B are assembled into an assembly called C. C is painted in process 7 and inspected in process 8 . Each process has an average scrap rate Pi, i=1,,8, of 3%. The desired output for final product C is 5000 units. How many units should be produced from the A and B to meet the demand for C ? 6. Consider the following operations and determine the fractions of machines A and B needed to produce parts I, II, and III. Part I is routed to A then to B. Part II is routed to B then A. Part III is routed to A then B then A again. 200,000 parts are to be produced per year from each. No set ups are required between part changes on the machines. Determine the fractions, the minimum, and the maximum number of each machines needed
