$$Q$4$

Questions 1 to 4 are based on the followinz: Considerl the following flow process which consists of three process steps performed by three machines. Work is processed in batches at each step. Before a batch is processed at Step 1, the machine in step 1 has to be set up. During a setup, the machine is unable to process any product. No setups are needed at step 2 and step 3. 1 S MINUTE.PART 30 MINUTES .MNUTE,PART 2 MINUTE.PART 1. 2. 3. 4. Assume that the batch size is 50 parts, which step is the bottleneck? A. Step 1 B. Step 2 C. Step 3 D. Step 1 and step 2 E. Step 1 and step 3 Using batch size of 40 parts, what is the capacity of the whole process? (Pick the closest answer!) A. 1/100 batch per minute B. 1/90 batch per minute C. 1/80 batch per minute D. 1/31.5 batch per minute E. 0.48 batch per hour What's the minimum batch size that maximizes the capacity of the whole process? (Pick the closest answer!) A. 10 pans B. 20 pans C. 30 parts D. 40 pans E. 50 pans Using batch size of 30 pans, how long would it take to produce the first 20 parts starting with an empty system? Assume that the parts in the same batch have to stay together (no smaller transfer batches allowed) when transfer to step 2 and to step 3. However, a finished part can leave the system the moment it completes at Step 3. (Pick the closest answer!) A. B. C. D. E. 120 minutes 150 minutes 180 minutes 185 minutes 210 minutes
