Developing a multi-issue and flexible negotiation mechanism based on multi-agent systems in the automated interchange

Agent-based negotiation is one of the interesting approaches in the field of automated negotiation in the E-Commerce world. Establishment an automated negotiation needs to develop a mechanism for it and it is obvious that users would accept a mechanism that is reliable alternative for negotiating individual. Therefore, the need to developing efficient and reliable agent-based negotiation mechanism is being felt. In this paper we present a multi-issue negotiation mechanism. In each round of this mechanism a twofold proposal is presented that caused the time of negotiation decreases while increasing the efficiency of negotiation and probability to reach better solutions. To do this, we focused on reasoning model of negotiation; First the decision making model of each agent about received offer is developed and then a novel method for generating counter offer is proposed. Validity and efficiency of proposed negotiation mechanism is indicated via predefined conditions of literature and a numerical example is solved.
