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....

There are two urns that, between them, contain five balls. At each time step, one of the five balls is moved to the other urn. Let the state variable be the number of balls in Urn 1. Find the fixed vector. a) Draw a state transition diagram and find the transition matrix. b) Is this a regular chain? Is this an ergodic chain? c) Find the fixed vector. What is the probability that in the long run Urn 1 has...

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. Also...
