15 points) The XYZ company produces three products using mixed assembly on a line which is operated 10 hours per day for 300 days per year. The annua l demand forecast is as follows Product Forecast |Daily Minimum demand batclh 15000 9000 4500 50 30 3.333 2 a. Determine a mixed model production schedule for a daily batch, based on the minimum batch size for each product. (Show an exact schedule for a one hour duration) [A(4), B(2), C(1), A(3), B(2), C(1), A(3), B(2), C(1)] repeated 5 times every day b. Product A requires 3 units of component R. Product B requires 4 units of components R. If component R is manufactured internally at XYZ, how many kanbans would be required if lead time is 1 days, the safety factor is 30%, and container size is 100 units? Daily demand for R-50(3)+30(4)-270 units/day (270)00d+0.30) -3.51,4 c. By investing S3000 in the system, XYZ can reduce the lead time to 1/4 days. This system is expected to be in operation for 10 more years. Component think XYZ should invest the $3000 in the system? Why? K-(2700.250 +0.30)-0.875, 1 R has a value of $20/unit and the fraction holding cost is 20%. Do you 100 Change in inventory level -4(100)-1(100)]-300 units Change in investment-300(20)-$6000 reduction Decrease in holding cost-0.2(6000 $1200 per year Yes, invest a one time $3000 to save $1200 per year. 15 points) The XYZ company produces three products using mixed assembly on a line which is operated 10 hours per day for 300 days per year.
