Research On The Negotiation Of Multi-Agent System Integrating Trust

In the process of multiple Agent negotiation,trust value attracted less attention in related works.In fact,trust value will directly affect the utility and strategy of negotiation.Most of previous works researched direct trust.However,it will lead to the sparse of trust relationship matrix if lacks the direct trust relationship,which may reduce the using efficiency of trust relationships.In addition,most Agent negotiation models set the Agent's round limit as a fixed parameter,but the actual negotiation model is not like this.In previous researches,there have been many achievements on the issues of Agent trust and negotiation,but few scholars have considered the impact of trust in the negotiation process.Agent trust and negotiation are not separate academic fields.During the negotiation process,the trust between Agents has a greater impact on the choice of its negotiation strategy.In response to the above issues,this article has carried out the following work based on previous research:(1)In this paper,the trust value is added to the negotiation model as a parameter.The negotiation model and the negotiation bid function are newly defined.Both the negotiation strategy and the bidding function of the Agent will be affected by the trust value of negotiating parties.(2)This paper considers the trust network formed by trust transfer,so that indirect trust is incorporated into the trust relationship.In this way,the trust relationship matrix is made denser,and forming a non-sparse trust matrix network.It also improving the availability of data.Agent negotiation success rate and efficiency have also improved.Comparison experiments prove that new model is more reliable than those models that do not consider trust attribute.The negotiation model has better performance on success rate and utility of negotiation.
