The average number of customers waiting, either in line (not counting those being served) or in the system (including those being served) The average length of time customers wait, either in line or in the system. Server utilization, i. e. , the proportion of time a server will be busy. The probability that an arriving customer will have to wait for service or will have to wait more than a specified length of time before being served. Number of servers and structure of queuing system. A supermarket may have one or more less than 10 items and self checkouts.
