B1 of 1 For HW #2, Please only answer questions 1a and 1b. EXERCISES 1. Skycell, a major European cell phone manufacturer, is mak- ing production plans for the coming year. Skycell has worked with its customers (the service providers) to come up with forecasts of monthly requirements (in thousands of phones) as shown in Table 8-10.1 Manufacturing is primarily an assembly operation. and capacity is governed by the number of people on the production line. The plant operates for 20 days a month. eight hours each day. One person can assemble a phone every 10 minutes. Workers are paid 20 euros per hour and a 50 percent premium for overtime. The plant currently employs 1.250 workers. Component costs for each cell phone total 20 euros. Given the rapid decline in component and finished-product prices, carrying inventory from one month to the next incurs a cost of 3 euros per phone per month. Skycell currently has a no-layoff policy in place. Overtime is limited to a maximum of 20 hours per month per employee. Assume that Skycell has a starting inventory of 50,000 units and wants to end the year with the same level of inventory. a. Assuming no backlogs, no subcontracting, and no new hires, what is the optimum production schedule? What is the annual cost of this schedule? b. Is there any value for management to negotiate an increase of allowed overtime per employee per month from 20 hours to 40?
