...JET Copies Case Problem page 1 Assignment #1: JET Copies Case Problem By: Jenna Kiragis Quantitative Methods 540 7/29/2012 JET Copies Case Problem page 2 Case Problem JET Copies is a copy business opened by James, Ernie, and Terri, three students who wanted to make it more convenient for other students in their apartment complex to get copies in a timely manner. After obtaining a copy machine for the business with a loan from Terri’s mother, the students soon began discussing the frequent breakdowns that may occur. It was then that the three decided they needed a backup copier. However, the students wanted to first have an estimate of how much money they would be losing if they did not have a backup copier (Taylor, 2010). This paper will discuss methods that simulate the number of days needed to repair the copier, the intervals between successive breakdowns, and the lost revenue for each day the copier is out of service. All of these methods together will simulate the lost revenue due to copier breakdowns over 1 year. JET Copies Case Problem page 3 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. Lost revenue of Jet Copies due to breakdown can be done by generating random numbers from different......
