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?

Assume a two-time-period model for a depletable resource, with identical demand functions in each of the tow time periods (i.e. P = 10 - 0.5q). The marginal cost of extraction is also constant for each of the two time periods (i.e. MC = $3). Calculate the dynamically efficient allocations of the depletable resource across the two time period when: (i) there are 20 units of the resouce available for use in total, and (ii) there are 30 units available.

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...
