A Fuzzy Negotiation Model of e-Commerce and Its Implementation

We usually decide to accept or reject the offer based on the utility function in the traditional automatic negotiation of e-commerce so that we reject the offers whose utility is lower than a specified value. Here we evaluate the acceptability based on the fuzzy set theory and the membership function. Since different issues have different effect on the negotiators, we state the combined concession in the multi-issue negotiation for the negotiators. We put forward a more practical negotiation model than the traditional negotiation model and state the process of a fuzzy multi-issue negotiation model of e-commerce to implement on computer, and we give pseudo-code program of negotiation by changing one issue at one time
