Some Practical Considerations in the Application of Finite Source Queueing Models.

This paper considers some practical aspects of an application of finite source machine repair queueing models. Exact models for small calling populations are developed to investigate a transient effects b the effect of assuming population items operate continuously, when, in fact, they may be idle a portion of the time and c the effect of having population items with unequal failure rates, but assuming all items fail at the population average values. Implications from the small population models and from models which bound and approximate larger population sizes are discussed.
