The Research Of Designing And Implementing Technology For Agent-Oriented Automated Negotiation System

With the continuous development and popularly apply of the computer technology and global networks, more and more complex, distributed application come out in front of us in the real world, and with the spring-up of ecommerce as a new trade pattern, more and more business affairs will be executed through the internet, which bring the attention that it's significant to study Automated Negotiation System which become one of the most important research areas. Automated Negotiation System that based on process negotiation model is one branch of Negotiation Support System, which use negotiation software agent to replace human wholly or partly to negotiate with other negotiators to solve the rgy-bargy problem in the trade, it greatly improves the efficiency, decreases the cost and advances the development of ecommerce, also with no limitation of time, location, and participants.The ultimate objective of Automated Negotiation is to implement an Automated Negotiation System with which has capability of making negotiation with counterparty automatically, it also has ability to accomplish sequential negotiation process. In fact, today there are so many researches and papers on Automated Negotiation System, especially the study in the fields which is in association with protocol, strategy, framework theories of negotiation, they fairly well established concepts. However, they still are short of completeness to sustain the implementation of Automated negotiation System, for which bring the seriousness of the disjoint of theory and practice are apparent. So the innovation of system realization is desirable in Automated Negotiation field, which in turn also advances researches in other subjects in this field.The research content of the paper as following:1. Application of logic reasoning and utility reasoning theory.Logic reasoning ability is one of characters of Agent, and utility is the weigh rule for satisfaction of reasoning object's demand, and also the foundation of decision-making. We explain the BDI from logic reasoning and utility reasoning in this paper, and express the logic model and utlity model in mathematics.2. Design session model of Agent Session is the way of Agent's relation making, and also communication. In order to predigest the way, we present four structures model. The model is the container of all function models, and also for understanding and implementation.3. Automated Negotiation System designingWe design the communication protocol, negotiation protocol, element model and strategy model in this paper, and finally integrate all models into a framework.4. Use Agent-Oriented methodology Prometheus to complete the designSpecification is perfect software's fundation, we use Agent-Oriented methodology Prometheus to design the system from system specification, system framework and detail design in this paper, which is suitable for Agent designing.5. Implement Automated model in Agent-Oriented tool JACKJACK support the Agent very well and also integrate all the funcation into the framework. We will use JACK to implement the system in this paper.6. Possible result set and run resultIn order to validate all the function models, we use maximize method to get the possible result of negotiation, which could compare the result of run.In this paper, the application background is negotiation support system based upon Agent in ecommerce. The research aspects relate to the theories and the methodology of communication, calculation, negotiation of Agent in the environment of multi-Agent system. Apply the Prometheus Methodology to modeling, design and implement Automated Negotiation System in the JACK Integration Develop Environment.
