Abstract

A novel graph model for conflict resolution was developed in the condition that decision-makers’ preference on states were not precisely determined in the Quality Negotiation stage in Complex Product supply-chain cooperation, in which the probabilities of grey number comparison were introduced to reflect participants hesitation for state priority. Specially, Petri net was utilized to describe the conflict evolutionary, which contained stage set, transition trigger and explosion rule. Grey numbers were used to reflect participants’ uncertain preference on several states and the probability of Petri net expansions can be calculated by comparing uncertain numbers. The equilibrium achieving condition were studied in the framework of Petri net, which can give direct proof for predicating potential Conflict solutions. The case of airframe quality standard in the negotiation stage of a certain commercial aircraft in China was conducted to reflect the feasibility and effectiveness of the previous model and method.
