Performance evaluation of multiagent information retrieval systems

In Multiagent Systems, the time of response to a client's request is one of the fundamental problems. This time is combined from agent activity times and inter-agent communication times. Many Multiagent Systems design methods are based on UML or its modifications. Performance evaluation is mainly based on system dynamics. In the UML, the most extensive models of dynamics are statecharts. The Performance statecharts are extensions of statecharts that contain probability distribution for activity duration times and probability distributions in order to solve non-determinism. A performance analysis of the information retrieval system with three types of agents using the performance statecharts is presented.
