- At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.arrow_forwardThe number of yearly breakdowns for the power generator observed over the past 20 years at Orlando Utilities is presented in the following data: Number of breakdowns 0 1 2 3 4 5 6 Number of years in which breakdowns occurred 2 2 5 4 5 2 0 For Orlando Utilities, the expected number of breakdowns = (round your response to two decimal places).arrow_forwardFC.51 Madison Memorial Hopsital is considering purchasing a new ambulance.

If such accounts become delinquent, their information is sent to the collection system via the IBS FILE (see appendix D). This file is sent to the collection system on a daily basis. Besides being used to update the collection history database it is used to generate the IBS new accounts report. Recall that the predictive dialer software is used as part of the collection process. It involves using packaged software to contact delinquent borrowers. Using a file of telephone and account numbers the software takes into consideration how many collection agents are working at the given time and paces the calls accordingly. This will assure that an agent will be available to take the call if a delinquent customer answers the telephone when the dialer places the call. When a customer answers the…arrow_forward
