PROBLEM #1. Worth 10 points Part X requires machining on a milling machine (operations A and B are required). Part Y requires machining on the same type of milling machine (operation A and C are required). Find the number of machines required to produce 4500 parts X and 7600 parts Y per week. Assume the company will be operating six days per week, 16 hours per day. The following information is given: Operation STD time Efficiency Reliability Defect rate 2.5 min 95% 95% 0.3% 0.02 hours 95% 92% 6.6% C 4 min90% 97% 5% Note: The milling machine requires tool changes and preventive maintenance after every lot of 500 parts X and every 400 parts Y. These changes require 35 minutes. PROBLEM #2. Worth 10 points Consider a manufacturing process as illustrated in the given figure. Assuming that demand is 2,300 units, what is the required input to meet demand? Assume that the scrap cost is $3 at process 1, $10 at process 2, $7 at process 3, and $13 at process 4. Compute the total scrap cost for the given system and the system where the scrap rates are reversed. Which system would be preferred? 1 yumruu 111 U UIU! 11sSUIC Il ss 3, and $13 at process 4.
