Real-time multiserver system with two non-identical channels and limited maintenance facilities Original Research Article

A real-time multiserver (such as unmanned air vehicles or machine controllers) system with two different channels (such as surveillance regions or assembly lines) working under maximum load regime with limited maintenance facilities is studied. In such system, a job is served immediately upon arrival (conditional on system availability) without delay. That part of the job which is not processed immediately is lost forever and cannot be served later. We show how to compute steady-state probabilities of such a system, when both maintenance and service times are exponentially distributed. Then, we also compute various important performance characteristics, including system availability and loss penalty function.
