Evaluating of TRB Stamping Process Plans Based on Theory of Fuzzy Set Barycenter

摘要

Generalizing tailor rolled blank applied in panels is one of efficient approach for automobile realizing lightweight, the stamping process plans based on general blank are affirmed even depending on experience, the uncertainty of plans decision-making must greatly boost up if TRB will be applied in panels. Theory of fuzzy set barycenter was put forward to decision-make plans in paper, the algorithm for obtaining attribute weight based on Fuzzy Complementary Judgement Matrices was bring forward. Because weights of some factors is relative small,if using uaual synthetical evaluation, in will result problems of “submerge” and losing evaluating information.Finally, calculating approach was clarified by a panel. the result shows that TRB process plan besed on TFSB is more reasonable and practical.
