Problem 1 Consider the following batch-flow process consisting of three process steps performed by three machines: Step 1 Step 2 Step 3 Activity or task time: 0.30 min/part Activity or task time: 0.24 min part Activity or task time: 0.15 min/part Setup time: 30 min Setup time: 25 min Setup time: 45 min Work is processed in batches at each step. Before a batch is processed at a step, the machine at that step must be set up. (During a setup, the machine is unable to process any product.) Assume that there is a dedicated setup operator for each machine (i.e., there is always someone available to perform a setup at cach machine). a) What is the capacity of step 1 if the batch size is 35 parts? b) For what range of the batch size is step 1 the bottleneck? [I am looking for an answer such as, for example, step 1 being bottleneck with a batch size between 5 and 10.)
