Queuing theory is the study of waiting lines. It is one of the oldest and most widely used quantitative analysis techniques. The three basic components of a queuing process are arrivals, service facilities, and the actual waiting line. Analytical models of waiting lines can help managers evaluate the cost and effectiveness of service systems.
