 Question 560153: A company produces a product on a number of machines. Each machine generates between \$200 and \$400 of revenue per day according to the uniform probability distribution. When a machine breaks down, it must be repaired, and the repair time may take 1, 2, or 3 days to be completed according to the following probability distribution: Repair time in Days Probability 1 0.30 2 0.45 3 0.25 The company would like to know whether it should purchase a back-up machine at a cost of \$6000. The management has decided that if the loss of revenue due to machine downtime was \$9000 or more per year, then a back-up machine should be purchased. In order to perform the comparison, the management decided to develop a simulation model for this situation. To develop this model, they first needed to know the time between breakdowns. According to their estimate, the time between breakdowns is between 0 and 8 weeks, with the probability increasing the longer the machine went without breaking down. Thus the probability distribution of breakdowns looked like the following: Perform an annual simulation and determine the loss of revenue due to machine breakdown. Next, decide whether a back-up machine would be needed. Show all work and explain your results. Please note that points are deducted if clear explanations are not included with the solutions.
