Question 6 (Setup Everywhere) Consider the following batch-flow process consisting of three process steps performed by three machines. Process Step Step 1 Step 2 Step 3 Processing Time 0.25min./unit Setup time 30 min 0.20 min./unit 20 min 0.15 min./unit 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 each machine.) a. What is the capacity of step 1 if the batch size is 35 parts? b. For what batch sizes is step 1 (2, 3) the bottleneck?

Mr. K’s is a very popular hair salon. It offers high quality hairstyling andphysical relaxation services at a reasonable price, so it always has unlimiteddemand. The service process includes five activities that are conducted inthe sequence described below ( the time required for each activity is shownin parenthesis):Activity 1: Welcome a guest and offer homemade herb tea (10 minutes)Activity 2: Wash and condition har (10 minutes)Activity 3: Neck, shoulder, and back stress release massage (10 minutes)Activity 4: Design and hair style and do the hair (25 minutes)Activity 5: Ring up the guest bill (5 minutes)Each activity has one employee dedicated to it. For the following questions,assume unlimited demand. Also assume that the employee at activity 1 onlyadmits new guests at the rate of the bottleneck.(a) Which resource is the bottleneck?(b) What is the capacity of the process?(c) What is the flow rate?(d) What is the utilization of the employee at activity 3(e) What is the cycle time?
n a manufacturing process, a molded part spends 7 hours in inventory before being placed in a deburring machine, where the part is processed for 2 minutes. After deburring, the part spends 4 hours in inventory waiting for its turn on the polishing machine. The part then spends 7 minutes in polishing before waiting 6 hours in line to be painted. The part goes through a painting process that takes 7 minutes, then spends 11 hours in inventory before being shipped to the customer. What is the percentage of value-added time for the part?
