RESUMO

Reallarge scale systems consisting of physically interconnected subsystems dis ributed in space, frequently involve a decentralization of control among several decision makers with different and usually conflicting als hen more than one decision maker, D M, is involved, dynamic games theory and hierarchical approaches ould be consid ered. ln this sense, the dynamic game viewed as an organizational task can be mapped onto a computeI network where each local decision is associated to a computeI . For the parallel and distributed computation of dynamic games. this thesis studies some important aspects. Firstly, the proposal of an ynchronous distributed game where the distribuition of the decision makers over the computeI network allows the matching algorithm/hardware. For doing this, the Stackelberg concept is idened to include multilevel games where the D.M sare assumed to be divided into t o groups: a group of leaders (multiple coordinators) and a group of followers (local controlers), and every DM may or may not be cooperating within his own group. ln this sense e propose an heterarchical distributed optimization methodology that inyolves temporal and spatial decomposition schemes with coordination distribution based on open-Ioop Stackelberg, Nash, Pareto and Team strategies. Secondly, we propose implementation forms for the proposed de cision algorithms on the parallel, vectorial and distributed computeI architectures, with the objectives of computational rformance imprO ement and of on-line decision making through the algorithms parallelism and vectorizati_n degrees exploration for the individual decisions achievement and through the decision makers distributed computation. Thirdly, a distributed multidecision making suport soft are over a workstation network was developed
