Operation Research Notes Pdf Introduction to Operation Research: The British/Europeans refer to “operational research”, the Americans to “operations research” – but both are often shortened to just “OR” (which is the term we will use). Another term which is used for this field is “management science” (“MS”). The Americans sometimes combine the terms OR and MS together and say “OR/MS” or “ORMS”. Yet other terms sometimes used are “industrial engineering” (“IE”), “decision science” (“DS”), and “problem-solving”.

• A TV repairman finds that the time spent on his jobs has an exponential distribution with mean 30 minutes. If he repairs sets in the order in which they come in, and if the arrival of sets is approximately Poison with an average rate of 10 per 8 hour day, what is repairman’s expected idle time each day?
