In this paper we analyse three well known logics (proposi-tional, first order predicate and propositional linear temporal logics) using a unified methodology. For each logic, we start by defining the syntax by constructively building a language L, followed by the semantics based on the notion of structure S : L → B, where B is the support set for a boolean(More)
We have created a framework for the development of a multi-agent system to control a group of elevators. This control system, besides real time useful response, must fulfill stability, massive concurrency and correctness requirements. These lead to the necessity of a highly evolved inter-agent negotiation protocol. We introduced a " contract net " like(More)
