Unformatted text preview: OR Models Problem Set #7 Fall Semester 2011 No Due Date In each problem, formulate as a Markov chain means that you should (i) clearly define the states and (ii) rate-transition diagram. For the following questions, use the Markov Processes (CTMC) Add-In, along with your own calculations, to answer the following questions. You should also formulate the balance equations. 1. A manufacturing line is being designed with the idea that it should be operational with only minimal maintenance for three weeks. (Every three weeks, significant preventative maintenance work is done by a visiting maintenance engineer.) A physically small but particularly important subsystem of the line has an exponentially distributed failure time with a mean of five weeks.
