What are the expected number of yearly breakdownsfor the power generator at Orlando Utilities that has exhibited thefollowing data over the past 20 years?
The materials handling manager of a manufacturing company is trying to forecast the cost of maintenance for the company's fleet of over-the-road tractors. The manager believes that the
cost of maintaining the tractors increases with their age. The following data was collected:

a. Use POM for Windows' least squares-linear regression module to develop a relationship to forecast the yearly maintenance cost based on the age of a tractor. (Enter your responses
rounded to three decimal places and include a minus sign if necessary.)
Y = 365.727 + 110,721 X
where Y = Yearly maintenance cost in dollars and X= Age in years.

- 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_forwardTucson Machinery, Inc., manufactures numerically controlled machines, which sell for an average price of $14.0 million each.

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_forwardDiscuss what we mean by multipole moments.arrow_forward

Theoretically, the percentage of defectives is dependent on temperature, humidity, and the level of artisan expertise. Complete historical data are available for the following variables on a daily basis for a year.a. Temperature (high, normal, low)b. Humidity (high, normal, low)c. Artisan expertise (expert, average, mediocre)Some experts feel that defectives also depend on productive supervisors.
