A Development of Multi-Agent based Automated Negotiation System

Nowadays, many researches are being been made for the development of new transaction system in an effort to transform current off-line system into on-line one. However, these researches mainly focuses on ordinary commercial transaction system, i.e. the one that supports fixed price transaction, in which consumers usually ought to buy goods at the price offered by sellers. Accordingly, more studies are to be made for the system to support both buyers and sellers in searching the proper price level through negotiations. Under current e-commerce environment, an automated negotiation system is badly needed to respond quickly and flexibly to the diverse environmental changes and also to perform many negotiations consistently and effectively. To this end, this paper has developed a multi-agent based automated negotiation system. This new system creates multi-issue negotiation proposals automatically, evaluating the counterpart’s proposal, and then, if necessary, preparing and sending counter proposals time and again, and finally accepting or rejecting.
