7. Consider a two-step, serial, production process with one resource at each step. The processing time at step 1 is 10 minutes and the processing time at step 2 is 5 minutes. There is ample supply of raw materials for step 1 and ample demand.

a) What is the capacity of this process in units per hour?

b) Suppose there is variability in the processing time at step 2. Specifically, the coefficient of variation of processing time at step 2 is 2. However, there is no variability in the processing time at step 1. Now what is the total time needed for a part to go through step 2?

Hint: Total time includes processing and waiting. If step 1 is always working and processing time there is 5 minutes, how much time passes between units arriving at step 2?

c) Now what is the capacity of this process in units per hour?

Consider a four-step serial process with processing times given in the following list. There is one machine at each step of the process, and this is a machine-paced process. bullet Step 1: 25 minutes per unit bullet Step 2: 15 minutes per unit bullet Step 3: 30 minutes per unit bullet Step 4: 20 minutes per unit Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of 105 units?

A service process has three serial stages. The defect percentage at stage one is 7%. The defect percentage at stage two is 13%. And, the defect percentage at stage three is 15%. Use 5 decimals for probabilities and 2 decimals for sigma levels in the following situations. (a)[2] Situation A: the connection logic of the three stages is that a good overall outcome only happens if all three stages individually have good outcomes. Draw the event tree for this situation....

A laptop manufacturing company has implemented a 2-step process to test the quality of each production batch. In the first step, a technician randomly selects 15 laptops from the batch and determines whether they meet specifications. The batch is considered acceptable provided no more than 1 laptop fails to meet specifications. Otherwise, the entire batch must be tested in the second step. Historical data shows that 95% of the laptops produced adhere to specifications. Discuss the following: What are the...
