Partial Question 20 1.67 / 5 pts You have been asked to analyze the capacity of the lasting department" of a shoe manufacturer (A "last" is a wooden from in the shape of a foot). The batch size is 100 pairs of shoes. Each pair in a batch is exactly the same style, size and color. The plant operates 8 hours per day. In the lasting department, the upper part of the shoe is stitched to the sole and the completed shoe is inspected, packed and readied for shipment. All operations are performed along a mechanized conveyor belt. Every operation is paced by the bottleneck on the line. There are 5 stations on the conveyor belt, one person per station, no buffer on the belt. Shoes arrive and leave in batches to this department, but shoes are processed in individual pairs on the line. A new batch is not started on the conveyor until the previous batch is completed by Station 5. Processing times are given below. Station Processing time/pair 1 Staple sole 0.7 2 Seat lasts 0.6 3 Rough sole 1.0 4 Cement sole 0.9 5 inspect 0.3 What is the daily batch capacity? Answer: In this case, CT for a batch is same as TP for a batch (because A new batch is not started on the conveyor until the previous batch is completed by Station 5). Therefore, CT = 350 mins/batch Available time = 480 mins/day 1.37 Capacity = Available time/CT = .62 batches/day
