Question - Now you plan to make a letter B by yourself. The stages to make a B should be (in this order) A: Bend a small straight piece to U form, B: Bend another small straight piece to U form, C: Make a strong straight base piece, D: Attach the two smaller U pieces to the base piece to creat a B. Assume the following amount of work in seconds is required at each station: A: 30 secs, B: 27 secs, C: 46 secs, and D: 60 secs. Furthermore, assume three class mates come over, and each of you is assigned to exactly one task (A-D). (Assume you want to make many Bs, i.e., perform the calculations for a continuous process.)

Part a: What is the flow time (from raw material to the finished B)? Please give your answer in seconds.

Part b: What is the bottleneck stage? A, B, C, or D?

Part c: What is the capacity rate of your process (Bs per hour)?

Part d: What is the cycle time of your process (secs)?

Part e: What is the average utilization of your resources (in %)?

Part f: Additionally, your brother/sister/friend wants to know what you are doing and is happy to join in. What is the best way in which (s)he can help (assuming that (s)he can only help with one particular task)? (Assume you want to make many Bs, i.e., perform the calculations for a continuous process.) Please explain in one short sentence.

Part g: With this additional helper, what is the new flow time (from raw material to the finished B)? Please give your answer in seconds.

Part h: What is the new bottleneck stage? A, B, C, or D?

Part i: What is the new capacity rate of your process (Bs per hour)?

Part j: What is the new cycle time of your process (secs)?

Part k: What is the average utilization of your resources now (in %)?
