Document Summary
Queuing theory the body of knowledge dealing with waiting lines. Operating characteristics the performance measures for a waiting line, including the probability that no units are in the system, average number of units in the waiting line, etc. Single-channel waiting line a waiting line with only one service facility ex. At a burger joint, each customer entering the restaurant must pass through one channel one order-taking and order-filling station to place an order, pay the bill and receive food. When more customers arrive than can be served immediately, they form a waiting line and wait for the order-taking and order-filling station to become available. Defining the arrival process for a waiting line involves determining the probability distribution for the number of arrivals in a given period of time . For many waiting line situations, arrivals occur randomly & independently of others, and we cannot predict when an arrival will occur.
