Waiting Lines & Queuing Models American Military University Business 312 For my project on other operations research techniques I have decided to research waiting lines and queuing models. My interest in this application stems from my personal dislike for standing in lines and waiting on hold while on the phone. This is virtually my only pet peeve; nothing aggravates me faster than standing in a line or waiting on hold. Like most people I go out of my way to avoid lines‚ using strategies

Based on information obtained from similar information desks‚ it is believed that people will arrive at the desk at the rate of 20 per hour. It takes an average of 2 minutes to answer a question. It is assumed that arrivals are Poisson and answer times

Analyzing Waiting Lines Most people find waiting lines irritating – waiting is idle and nonproductive time. From a service system perspective‚ however‚ a line represents a demand for service. Think of a restaurant on a Friday night. As a customer it is an irritation to have to wait 40 plus minutes for a table‚ but from the restaurant’s perspective‚ if there is not a line‚ then that means there are empty tables. Idle services are not good. So management must balance waiting time with the

CHAPTER 18 Management of WAITING LINES KEY IDEAS 1. Waiting lines are an important consideration in capacity planning. Waiting lines tie up additional resources (waiting space‚ time‚ etc.); they decrease the level of customer service: and they require additional capacity to reduce them. 2. Waiting lines occur whenever demand for service exceeds capacity (supply). Even in systems that are underloaded‚ waiting lines tend to form if arrival and service patterns are highly variable because
