抄録
Generally speaking in responsive systems, component processors may be isolated or added dynamically due to their faults and repairs. Such an action to change system configuration is called reconfiguration. A reconfiguration action incurs loss of performance due to deadline violations since the action may entail an overhead for recovery. In order to exactly evaluate performability measures of such systems, this factor of reconfiguration should be taken into account. In most of the previous approaches, however, the overhead is not explicitly considered. In this paper, we propose a framework for modeling and evaluating responsive systems which uses extended Markov reward models. The proposed model can represent the loss caused by a reconfiguration action. Then we give an example of modeling and performability evaluation. Finally based on condition for executing a reconfiguration action, we develop a good reconfiguration strategy to improve the performability of the system.
