Research On Bilateral Multi-issue Automated Negotiation

With the rapid growth of Internet, autonomous software agents, which can be viewed as delegates of human beings in the cyberspace, have draws much attention in recent years because of their potential capacity to radically change the current style of practicing e-commerce. Agent-based automated negotiation technology has the potential to radically change the way with which information technology was conducted.In this thesis, we present a novel model for bilateral multi-issue automated negotiation. Instead of focusing on the predicted outcomes, our method emphasizes the negotiation process itself. Specially, we illustrate a sequential decision-making negotiation process. At each negotiation iteration, an agent checks the history of the process and updates its beliefs about its opponents and then tries to maximize its own expected payoff based on its own subjective beliefs.The major research work in this thesis can be viewed as follow.1. To construct a bilateral multi-issue automated negotiation system based on agentIn this part, we firstly describe the formalization system, fractionize the types of negotiation issue, and discuss the protocol and flow for negotiation. Communication is the mainly method in negotiation, so in our thesis we also present the basic primitive for negotiation based on speech act theory. At last, the interactive algorithm in negotiation system is introducted.2. To establish the BDI model between seller and buyer in automated negotiation systemDuring negotiation, the agents who participate in automated negotiation have different mental states, so how to construct BDI system is the most important part in negotiation system. In second part, our firstly define theBDI Model for seller and buyer, then introduce the BDI revised algorithmfor seller in negotiation. At same time, the method to catch the mental state of buyer in negotiation communication is also discussed. Finally, the mental factor which should be considered in negotiation from psychology viewpoint is presented.3. To put forward the dynamic strategy based on time in negotiation systemTime is an important factor for negotiation, our research also discuss this point. In this thesis, we mainly research the dynamic negotiation strategy based on time. We firstly analyze the motivation in negotiation,...
