Mathematical Model on Stationary Information System in a Distributed Service Network

In Distributed Service Network, the main concern of the user is mostly focused on the immediate response time of a call for service. The user evaluates the efficiency of a service network in terms of how long he or she has been waiting until a service unit arrives at the scene of a call. Short-term policies such as dispatching, repositioning or routing depend critically on the information available and the communications system operated by the dispatcher at the moment a service request arises. Thus, information has great value in distributed service network. In this paper the mathematical model is proposed for the expected response time under stationary information system.
