Negotiation Process based on Hybrid Trader with Side Payment

This paper proposes new cooperation business model on B2B/B2C and shows effectiveness of our proposed model. We call general consumers who stand on seller hybrid traders. Ordinarily, a trader who is general consumer doesn't have enough money. We consider about traders cooperate with each other. In regard to buying items, we consider a volume discount-based trading. We propose a mechanism in which trader cooperates, buys in a lot of goods, and increases own utility. Our mechanism adopts side payment to promote increasingly cooperation with traders. Cooperative traders commit participation based on a value of side payment. Our mechanism searches for the best value of side payment in cooperation and negotiation. In our simulation, we show relationships between side payment and trader's utility.The original publication is available at JAIST Press http://www.jaist.ac.jp/library/jaist-press/index.htmlKICSS 2007 : The Second International Conference on Knowledge, Information and Creativity Support Systems : PROCEEDINGS OF THE CONFERENCE, November 5-7, 2007, [Ishikawa High-Tech Conference Center, Nomi, Ishikawa, JAPAN
