Bilateral and Multi issue Autonomous Negotiation Model Based on Sellers’ Multi proposal

Abstract:

To support the electronic transaction,a multi issue autonomous negotiation model based on sellers’ multi proposals and buyers’ evaluation is presented with the premise of private information and limited time.The strategy of the buyer agent is simplified to evaluate the one or several proposals generated by the seller agent in every round of negotiation.The seller agent,according to time or/and resource dependent strategy,calculates the whole utility concession;and different combinations of conceded issues and the utility reduction of each are decided on the basis of the buyer’s evaluation and the negotiation history.Then,several new proposals of the same utility are put forward by the seller.This model helps to relieve the system of communication and computation burden,speed up the convergence of result and improve the efficiency and quality of the negotiation with a good joint utility when the buyer utility function is linear.

Key words:multi issue negotiation; negotiation model; negotiation strategy; multi agent system
