The integrated energy service system for a specific area is supposed to deliver electric and thermal energy in an integrated manner for the purpose of reducing cost, primary energy consumption, and CO2 emission. Under an assumption of the service system, this paper develops a multi-objective optimization model for determining urban energy systems. Considering the various energy system alternatives, such as photovoltaic generations for residential houses and fuel-cell cogenerations for business and commercial customers, the model determines the share of the energy system alternatives in order to minimize the above three indices. As numerical examples, this paper illustrates trade-off analyses in the case when the proposed model is applied to a 2 km x 2 km square area in Osaka. Finally, this paper illustrates the role of various energy system alternatives from CO2 reduction and fossil energy reduction points of view. (C) 2004 Wiley Periodicals, Inc.

This paper explores issues of electronic commerce as a key enabler to promote trade between buyers and sellers. The broker is processed to match buyers and sellers, which is significant in prompting the transactions between the two sides. This paper proposes an agent-based framework for matching buyers and sellers and uses the multi-objective optimization model to match sellers and buyers. The framework is processed in three layers: the interface layer, the matching layer and the database layer. The interface layer consists of buyer agents, seller agents and a broker agent. The matching layer is mainly to find the appropriate sellers to buyers. Based on the framework, a prototype system has been designed to illustrate the effectiveness of the approach.
