Recreate the given figure for a call center that wants to achieve a 40 percent no hold rate. Suppose that agents only become cost effective (where the revenue they generate exceeds their cost) if they have 90 percent utilization. How large, in terms of number of agents, does the call center need to be to have agents that are generating a positive profit? If mean call time is 5 minutes, what would the arrival rate need to be for 90 percent agent utilization with this many agents?

11. Suppose that in the year 2011, Celestial Electronics planned to produce 950,000 units of its portable GPS devices. Of the 950,000 it planned to produce, a total of 25,000 units would be added t0 the inventory at its new plant in Florida. Also assume that these units have been selling at a price of $100 each and that the price has been constant over time. Suppose further that this year the firm built a new plant for $5 million and acquired S2.5 million worth of equipment. It had no other investment projects, and to avoid complications, assume no depreciation. Now suppose that at the end of the year, Celestial had produced 950,000 units but had only sold 900,000 units and that inven- tories now contained 50,000 units more than they had at the beginning of the year. At $100 each, that means that the firm added $5,000,000 in new inventory. 8. How much did Celestial actually invesı this year? b. How much did it plan to invest? c. Would Celestial produce more or fewer units next year?…
