KENDALL’S NOTATION

Kendall’s Notation is a system of notation according to which the various characteristics of a queuing model are identified.

Kendall (Kendall, 1951) has introduced a set of notations which have become standard in the literature of queuing models. A general queuing system is denoted by (a/b/c): (d/e) where

a

=

probability distribution of the interarrival time.

b

=

probability distribution of the service time.

c

=

number of servers in the system.

d

=

maximum number of customers allowed in the system.

e

=

queue discipline

In addition, the size of the population is important for certain types of queuing problem although not explicitly mentioned in the Kendall’s notation. Traditionally, the exponential distribution .
