Assignment #1: JET Copies Case Problem

Read the “JET Copies” Case Problem on pages 678-679 of the text.  Using simulation estimate the loss of revenue due to copier breakdown for one year, as follows: 1. In Excel, use a suitable method for generating the number of days needed to repair the copier, when it is out of service, according to the discrete distribution shown. 2. In Excel, use a suitable method for simulating the interval between successive breakdowns, according to the continuous distribution shown.  3. In Excel, use a suitable method for simulating the lost revenue for each day the copier is out of service. 4. Put all of this together to simulate the lost revenue due to copier breakdowns over 1 year to answer the question asked in the case study.  5. In a word processing program, write a brief description/explanation of how you implemented each component of the model.  Write 1-2 paragraphs for each component of the model (days-to-repair; interval between breakdowns; lost revenue; putting it together).  6. Answer the question posed in the case study.  How confident are you that this answer is a good one?  What are the limits of the study?  Write at least one paragraph.

Case Problem
James Banks was standing in line next to Robin Cole at Klecko’s Copy Center, waiting to use one of the copy machines. “ Gee, Robin, I hate this,” he said. “We have to drive all the way over here from Southgate and then wait in line to use these copy machines. I hate wasting time like this.” “I know what you mean,” said Robin. “And look who’s here. A lot of these students are from Southgate Apartments or one of the other apartments near us. It seems as though it would be more logical if Klecko’s would move its operation over to us, instead of all of us coming over here.” James looked around and noticed what Robin was talking about. Robin and he were students at State University, and most of the customers at Klecko’s were also students. As Robin...
