TYPES OF QUEUING MODELS

TYPES OF QUEUING MODELS

Different types of models are in use. The three possible types of categories are:

  1. a.    Deterministic Model. Where the arrival and service rates are known. This is rarely used as it is not a practical model.
  2. b.   Probabilitistic Model. Here both the parameters i.e., the arrival rate as also the service rate are unknown and are assumed random in nature probability distribution i.e., Poissons, Exponential or Erlang distributions are used.
  3. c.    Mixed Model. Where one of the parameters out of the two is known and the other is unknown
