State Kendalls notation

Kendall’s notation:  A/B/C/K/m/Z

A, Inter-arrival distribution

  • M exponential
  • D constant or deterministic
  • Ek Erlang
  • G General

B, Service time distribution

  • Same as above

C, Number of Servers

K, Capacity (maximum number of requests/customers allowed)of the system. Includes request/customers in the queue as well as those being service.

m  Population size (number of customers that might enter or request services)

Z Service Discipline - this can include such systems as FIFO(First In, First Out), LIFO(abbreviated as Last In, First Out), SIRO (abbreviated as Service In Random Order), Pxxx (Priority service, preemptive and non-preemptive)
