Question 2 [5 points] A tandem hard drive assembly line consists of four workers and two product models ('C' and 'F'). Each workers is allowed to take two 15-minute breaks and one 30-minute lunch out of her own eight hour shift. An industrial engineer decides to analysis this system by measuring started time, completed time, and processing time of each product as shown in the following table. (a) [1 point] Which worker is the bottleneck? How do you physically identify the bottleneck worker in an operation? (b) [1 point] Which workers that you observe learning curve effect? Justify you answer (c) [1 point ] What are expected average and maximum throughput of this assembly line if a regular shift is 8 hours? (d) [2 points] If the speed of workers can be ranked from the slowest to the fastest as: A CB
