Abstract

Recently, many researchers have tried to establish EC framework for automated contract and brokerage using agent technologies in electronic commerce. Traditional researches, however, often enforced the user''s participations during the automated brokerage process of agents and did not supported the procedures and methodologies for satisfying various user''s requirements. In this paper, we propose a brokerage framework based on multi-agent to overcome the defects of the previous researches. For the optimal brokerage, the proposed framework is divided into two layers, which are called competition layer and constraint satisfaction layer. The agents process behaviors of brokerage through two layers according to the proposed message driven communication protocol. We also apply CSP (Constraint Satisfaction Problems) techniques to brokerage process to satisfy various preferential requirements from the user. That is, we model the relationship between buyer agents and seller agents using CSP and propose efficient CSP models for the optimal brokerage as the types of brokerages. Finally, we implemented prototype systems applying the proposed framework and showed the efficiency of the proposed framework with the experimental results.
