Exact Aggregation in Exponential Queueing Networks

Abstract

Aggregation as often used for the mvestlgat~on of large systems This techmqu is pamculafly attracuve for nearly completely decomposable systems It as essentmlly an approxunate method, but at remains attractave since the error ,s small and bounds for at can be obtamed We are concerned here w,th aggregauon m exponential queuemg network analysas, and more precisely wath the condmons under which aggregation will yaeld exact results
