| With the increase of the product's complexity, the development of product more and more trends towards the collaborative working of many discipline's experts. Using multi-discipline collaborative design, all discipline performances of the product can be thought as a whole, the conflict among disciplines can be harmonized and solved. As a result, the development cycle and cost can be reduced, and product quality can be improved.This paper describes a system of multi-discipline collaborative design based on the Three-layers-organization and distributed component technique. Based on these, we establish a multi-discipline collaborative design model and decision support system, and achieve communication among multiple disciplines through using XML language and RMI technique. In the part of negotiation among multiple disciplines, a kind of group negotiation strategy considered negotiation time, resource and other various factors is brought forward. Payoff (Utility) function in the Game theory is used to simulate the action of negotiators, and using Fuzzy sets theory and Pareto optimal principle to guide the process of negotiation, and receiving Pareto optimal solution through negotiation. In response to the situation of receiving not a few solutions through negotiation, we use fuzzy evaluation technique to evaluate and receive a local optimal solution. Last, we synthesize all local optimal solutions and receive product design scheme through fuzzy membership degree method. In the process of negotiation and decision, we develop the communication method and negotiation language among disciplines based on XML standard and RMI technique, and achieve XML wrapper and parser by JDOM technique. In order to solve the semantic mismatch problem in exchanging, concept of shared ontology is brought forward and OWL standard is used to construct technique shared ontology.According to the research method and technique above, a web-based...
