Queueing model

In queueing theory, queueing models can be represented using Kendall's notation:

A/B/S/K/N/Disc

Where:

• A is the interarrival time distribution
• B is the service time distribution
• S is the number of servers
• K is the system capacity
• N is the calling population
• Disc is the service discipline assumed

Some standard value of the notation include:

• M for a Markovian (exponential) distribution
• Eκ for an Erlang distribution with κ phases
• D for Deterministic (constant)
• G for General distribution

For example: M/M/1/$\infty$/$\infty$ represents a single server that has unlimited queue capacity and infinite calling population, the inter-arrival times follow the exponential distribution, so do the service times.
