A Fuzzy Concession Negotiation Strategy Based On Market-Driven Model

The transaction on the internet and the automatic negotiation is becoming more and more popular with the development of computer technology, the internet technology and the economic commerce, and as a new way of doing business, it is accepted by more and more people. The transaction and negotiation on the internet can save a lot of human resources, material resources and other importance resources than the traditional transaction and negotiation. The automatic negotiation on the internet, which does not need a fixed place with the others participators, can reduce a lot of side effect of the traditional transaction and negotiation and make it much easier to reach a deal.Very few automatic negotiations are designed with considering the effect of the changing market situation and the flexibility to relax their criteria to reach a consensus much more rapidly in the traditional ones, so that they reject the offers that is a little lower than a specified value very quickly, which decreases the rate of success and the average utility. Here with the changing market, a multi-lateral model based on market-driven negotiation is proposed, which can make different concession through considering factors such as time, competition and the distances from trading parties'proposals in the market, we design a Fuzzy controller system to get the entire value of the concession;The effect of the eagerness to reach a consensus of the buyers and sellers is also being considered, and then according to all the factors we propose a function of evolution. In order to simulate the model we propose a Relaxed-criteria negotiation protocol and arithmetic, including the evaluation of the offers, how to make concession and so on, and the model we designed reflect the dynamic and self-determination sufficiently.The negotiation model this paper proposed is more realistic than the traditional ones. This paper also makes a research on how to simulate the model on the computer. The time-based negotiation model and the fuzzy concession negotiation strategy based on market-driven model are evaluated in different situations. The results show that the methods this paper proposed is valid.
