Q10.2 (process with rework) consider the following three-stage production process of glass ceramics, which is operated as a worker-paced line. activity time: components: # 1- 6min / unit, #2 – 5min / unit, #3- 4min / unit to finished unitsthe process is experiencing severe quality problems related to insufficiently trained workers. specifically, 20 percent of the parts going through operation 1 are badly processed by the operator. rather than scrapping the unit, it is moved to a highly skilled rework operator, who can correct the mistake and finish up the unit completely within 15 minutes. the same problem occurs at station 2, where 10 percent of the parts are badly processed, requiring 10 minutes of rework. station 3 also has a 10 percent ratio of badly processed parts, each of them requiring 5 minutes by the rework operator. a. what is the utilization of station 2 if work is released into the process at a rate of 5 units per hour? b. where in the process is the bottleneck? why? (remember, the bottleneck is the resource with the lowest capacity, independent of demand.)c. what is the process capacity?

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.
