近年來，電子商務蓬勃地發展，各種研究與應用領域吸引了學者與專家投入研究。為了減少買賣雙方的交易成本，代理人(Agent)的技術被使用來發展自動化的商務環境。此外，行動代理人(Mobile Agent)的技術更賦予代理人程式在網路上自主移動的能力。基於上述的研究議題，本研究發展了以行動代理人為主的分散式交易的電子商場，在此環境下，買方指派代理人在網路上搜尋產品、並派遣代理人至供應商伺服器端與供應商的代理人交易，為了快速地完成交易，本研究使用多個代理人同時合作地完成交易。換句話說，買方根據供應商的數量同時指派多個代理人程式與供應商的代理人進行交易。在電子商務中，協商則是藉由買賣雙方的交換意見，來達到彼此的同意點。為了能反映實際世界的協商情況，本研究使用模糊推論法(Fuzzy Inference)來評量各供應商的提案，討論一個買方對應多個供應商的協商模式。在產業的導入方面，本研究以旅遊業的商務環境來作為我們的研究運用，例如，旅行社可以透過代理人與旅館進行訂房業務。本研究的目的是針對電子商場提供一個新的架構與合作的協商模式。
本研究有三項主要的研究成果：
(1) 建構一個以行動代理人為基礎並在供應方交易之B2B電子商場，採用旅遊業作為運用領域，提供一個具有彈性與效率的電子商場架構。
(2) 發展單一買方對應多個供應商的合作協商模式，買方可以同時指派多個代理人程式與供應商的代理人進行交易，以增加系統的效率。
(3) 為了能符合人類的思考模式，使用模糊推論的方法，來做為買方代理人在協商時評量供應商的提案。

Over the past few years, electronic commerce has been developed prosperously. There have been a lot of research and applications on it. In order to reduce the trade cost between buyers and sellers, agent technique has been utilized to develop environment for automatic commerce. Besides, mobile agent technique provided the mobility for agents in the network. On the basis of the above issues, this research developed an e-Marketplace system for mobile agents. In this system, the buyers assigned agents to search the goods information and dispatched agents to supplier sides and traded with supplier agents. In order to work efficiently, this search utilized multiple buyer agents to trade cooperatively and simultaneously. In other words, the buyer assigned multiple buyer agents to trade with supplier agents simultaneously according to the amount of supplier agents. For the negotiation in electronic commerce, it needed to exchange the information between buyers and sellers to reach to an agreement. In order to simulate the negotiation in the real world, this research utilized fuzzy inference to evaluate the proposals of suppliers for one buyer to multiple suppliers. For the application domain, the research took the tourism as an application domain to develop the e-Marketplace system. For example, a travel agency could utilize agents to make room reservations with hotel. This research purposed to provide an architecture and cooperative negotiation in the e-Marketplace for the tourism application.
This research had three major achievements:
(1) Constructing a B2B e-Marketplace system for mobile agents to providing a flexible and efficient architecture of system; Applying the tourism as an application domain to develop the e-Marketplace system.
(2) Developing an asynchronous cooperative negotiation mechanism for buyer to assign multiple agents to trade with supplier agents simultaneously in order to raise the efficiency of system.
(3) Utilizing fuzzy inference to evaluate the proposals of suppliers during negotiation in order to fit in with humans.
