Abstract: To solve the problem of several different businesses entities with different objective preferences and constraints which negotiating for a common decision in a distributed collaborative environment, an Agent-based distributed negotiation mechanism and algorithm was proposed. Intelligent Agent technology was used in this mechanism, where each Agent represented a business entity's interest to negotiate with others for a common decision. Concept of preference model was used in this negotiation mechanism. Agent's preferences and constraints in preference model were regarded as private information. Proposed global preference evaluation and conflict resolutions during negation were applied in this negotiation algorithm. This distributed negotiation algorithm was simulated via an example. The result of simulations showed that the global preference evaluation for proposes has made the negotiation result much more optimal, and besides, the using of conflict resolution during negotiation improved negotiation's success rate evidently. Finally, this Agent-based distributed negotiation algorithm's application was analyzed and extended.
