Question C: Explain why total output and % capacity utilization in Question B deterio- rate compared to the case in Question A despite the fact that average processing time of each machine in both Question A and Question B is 10 minutes. Question D: Increase number of the workstations from four to five and run the simulation. What happens to the total output and % capacity utilization? Explain why. Question E: Set number of workstations to four. Now, increase the standard deviation of processing time of each machine from 4 to 5. What happens to the total output? Explain why. Question F: In this question we will use simulation for decision making. Assume there are four machines and processing time in each machine is uniform with mean of 10 minutes and standard deviation of 4 minutes. Suppose that you were allowed to have only 1 unit of WIP inventory buffer in the entire processs. That one unit of WIP could be between machine 1 and 2, or between machine 2 and 3, or between machine 3 and 4. Where would you keep this buffer in order to maximize total output? lntuitively explain your observation from this simulation. Hint: One way to answer Question F is to place one unit of buffer between different stations, re-run the simulation, observe its impact on total output, then choose the spot that maximizes the total output. Part 2: Probability Warm-up Questions Question G: A normal die having six sides is rolled. If each of the six possible outcomes is equally likely, determine average and standard deviation of the number that appears. A batch of 5000 computer chips is produced in a manufacturing process. Assume that each chip has probability 0.001 of being faulty and the chips are statistically independent of one another. Question H: What is the distribution of the number of faulty chips in the batch? Question I: What is the expected number of faulty chips? Question J: What is the variance of the number of faulty chips? Question K: What is the probability that there are zero faulty chips BYou can set this in "Output Storage Area for Each Machine" OfDesign worksheet
