| Summary: | 碩士 === 靜宜大學 === 資訊管理學系研究所 === 91 === Today, there are many electronic commerce applications, however, the flexible negotiation between buyers and sellers is not widely used yet. In this paper, we propose a negotiation protocol supporting multi-attributes of products. Our negotiation protocol allows consumers to define qualitative and quantitative attributes of their required products. Besides, our protocol also supports consumers to describe their positive and negative attitude, and employ the weight to describe the degrees of attitude. Therefore, consumers can describe their favor clearly by our negotiation protocol. Meanwhile, in order to speed up the negotiation, we also provide a mobile agent based negotiation framework to support buyers and sellers to carry out their negotiation procedures.
Furthermore, according to the products of the single web site can not satisfy consumers completely, if the consumers want to buy a lot of products at a time, they must browse through numbers of web sites in order to complete the purchase. The restricts of costs of products which web sites support are different and the discount of commodities which are combined to sell, make the consumers may lose the option of minimum cost path. We also provide an algorithm to look for the minimum cost path from numerous combinations. To avoid browsing web sites in blind and computing the minimum cost path manually, we employ the architecture of mobile agents and provide the minimum cost path algorithm for the agent to help consumers complete the whole purchase.
In this thesis, we propose the multi-attributes negotiation protocol and the negotiation for combination of products are both based on mobile agent framework. We apply the properties of mobile agent to help consumers decrease working cost. As electronic commerce goes by, mobile agent system will play an important role between buyers and sellers.
