Research on collaborative negotiation for e-commerce

Collaborative negotiation is a new negotiation mechanism. It is a multi-thread negotiation and can effectively reduce the coordinative costs in negotiations. In this paper we firstly propose a constraint network to depict conflicts in the collaborative negotiation. Secondly, we use state diagram to define collaborative negotiation protocol. And finally based on the constraint network we present domain propagation algorithm to analyze the root conflict, and then design rule-based negotiation strategies to solve conflicts in negotiation processes.
