Distributed energy management case study: A formal approach to analyzing utility functions

Abstract

The service-oriented paradigm has been established to enable quicker development of new applications from already existing services. Service negotiation is a key technique to provide a way of deciding and choosing the most suitable service, out of possibly many services delivering similar functionality but having different response times, resource usages, prices, etc. In this paper, we present a formal approach to the clients-providers negotiation of distributed energy management. The models are described in our recently introduced REMES HDCL language, with timed automata semantics that allows us to apply UPPAALbased tools for model-checking various scenarios of service negotiation. Our target is to compute ways of reaching the price- and reliability-optimal values of the utility function, at the end of the service negotiation.
