    • 近年來，有許多的協商研究專注於如何使用軟體代理人以應用於電子商務協商和網際網路服務協商領域。本篇研究主要是考慮在仲介代理人收取仲介佣金的前提下，瞭解以往學者所提出的協商架構是否仍能達到公平性。在過去的研究文獻中，並沒有學者去探討這個問題。為了解答這個疑問，因此我們進行了模擬實驗。在模擬中，我們使用軟體代理人執行自動化協商中第三方仲介的角色，而模擬所得的結論就是三方協商架構在仲介代理人收取佣金的情形下，存在漏洞。因此，本篇研究從改善協商架構的角度出發，提出兩個新的協商架構以解決仲介代理人蓄意不公平的問題。經由模擬所提出的新的協商架構，我們證實提出的協商架構，可防止仲介代理人在收取佣金的環境下做出不公正的自利行為。同時，為達成雙向協商的模擬的效果，我們也提出一個在FIPA架構下，改良的雙向協商協定，達到參與協商的雙方皆可提出提案(proposal)之目的。

    In recent years, a lot of negotiation literatures pay considerable attention on using software agent to electronic commerce negotiation and web service negotiation applications. The specific aim of the thesis is to investigate the fairness of negotiation architectures proposed in previous research works under the consideration of brokerage commission situation. To answer this question, we conduct experiments by using software agents to simulate automatic service negotiation. Based on our simulation results we found that the mediator (broker agent) of third party negotiation architecture under brokerage commission situation presents biased behavior. To resolve this fairness problem, we present two new negotiation architectures in this thesis. Based on simulation results, the proposed architectures can successfully prevent broker’s biased behavior under the introduction of brokerage commission. In the meanwhile, we also introduce a modified two way negotiation protocol under FIPA agent framework to fulfill basic negotiation requirement by supporting proposal invocation and counter proposal invocation to both negotiating parties.
