BU275 Chapter Notes - Chapter 13: The Queue, Poisson Distribution, Exponential Distribution
Document Summary
Companies are able to reduce waiting time and provide faster service by increasing their service capacity. Increasing service capacity has a monetary cost and lies the basis of waiting line analysis: the trade off between the cost of improved service and cost of making customers wait. Most businesses have sufficient serving capacity available to handle their customers in the long run. Waiting lines occur b/c customers don"t arrive constantly and evenly, and aren"t served in an equal amount of time. Operating characteristics: average values for characteristics that describe the performance of a waiting system. Components of a waiting line system includes arrivals, servers, and waiting line structure. Queue discipline: order in which waiting customers are served. E. g. last-in first-out, random, predetermined schedule, or alphabetical. Calling population: source of customers; infinite or finite. E. g. store with number of potential customers has infinite calling population, truck with 20 trucks has finite calling population.
