For the batch flow process above, before a WS can be used it must be setup. While setup in ongoing a WS cannot process any product. Assume a dedicated setup operator exists for each WS. Given, process flows from Ws1 to Ws2 to Ws3 Setup Time for Work station 1 = 30 Processing Time Work station 1 = 0.25 min/unit Setup Time for Work station 2 = 20 min Processing Time Work station 2 = 0.20 min/unit Setup Time for Work station 3 = 45 min Processing Time Work station 3 = 0.15 min/unit a. What is the capacity of WS1 if the batch size for units is 35? b. For what batch size is WS1 the bottleneck? WS2 the bottleneck? WS3 the bottleneck? c. Explain how the process designer might use the takt time to identify the best batch size for each WS
