Abstract: To coordinate the conflict problem of performance requirement satisfaction with engineering characteristics,a conflict coordination method based on extension conductive transformation was presented.The hierarchical structure model of requirement was established through dividing customer base and establishing the corresponding product needs set.The requirement was mapped to the engineering characteristics by using Quality Function Deployment (QFD) method,and the conflict relationship among engineering characteristics could be obtained.The conductive chain of main product parts was built after analyzing the relevance between engineering characteristic and parts component.According to the method of extension formal modeling,the element model,conductive conflict net and conductive conflict circle of conflict factors were established.Thus the conflict model of engineering characteristics and parts was generated.The basic transformation base was obtained through extension logic reasoning.Meanwhile,the resolution algorithm steps and the procedure for the conflict problem were given.Screw compressor was taken as an example to coordinate the conflict between product noise performance optimization and the structure,and the effectiveness of proposed method was validated by solving the big noise problem in screw compressor's operating.
