Chapter 11

The mean number of customers or units arriving in a given period of time.

The average amount of time between consecutive arrivals to a waiting line, computed as the inverse of the arrival rate.

When arriving units cannot enter the waiting line because the system is full. these units can occur when waiting lines are not allowed or when waiting lines have a finite capacity

The average amount of time for a server to complete service on a customer, computed as the inverse of the service rate.

A probability distribution used to describe the service time for some waiting line models.

The population of customers or units that may seek service has a fixed and finite value.

The queue discipline that serves waiting units on a first come, first-served basis.

The population of customers or units that may seek service has no specified upper limit.

A waiting line with two or more parallel service facilities.

The performance measures for a waiting line, including the probability that no units are in the system, the average number of units in the waiting line, the average waiting time, and so on.

A probability distribution used to describe the arrival pattern for some waiting line models.

A waiting line.

The body of knowledge dealing with waiting lines.

The mean number of customers or units that can be served by one service facility in a given period of time.

A waiting line with only one service facility.

The normal operation of the waiting line after it has gone through a startup or transient period.

The startup period for a waiting line, occurring before the waiting line reaches a normal or steady-state operation.
