This chapter describes the mathematical and probability concepts that are the foundation for the remaining chapters of the book. This includes the Poisson, Exponential and Erlang distributions, the Postulates that define a queuing system, and also the difference, differential, equilbrium and reduced equations. The equilibrium and/or the reduced equations are used to generate the probability distribution on the number of units in the system, and the various performance measures of the system.
