Abstract: To solve the problem of comprehensive optimization of conflicts between quality and cost in the process of collaborative design,the quality cost multi-objective optimization problems was transformed into multi-objective game decision problems under dynamic alliances by introducing the game theory,and a game model that based on historical data was established.The game effect matrix formed by information indicated that due to the incompleteness of historical data,the multiple regression analysis was adopted to complete the game utility matrix,and a game model of conflict resolution based on historical data information was proposed.The game matrix was solved through Shapley value algorithm.The allocation solution of conflict was used to represent the best quality and cost comprehensiveness.To seek the contribution of each game player and verify the reliability of equilibrium results obtained by Shapley values,a quantitative assessment method for the contribution of Shapley values was proposed.An assembly process of a lathe spindle was used as an example to demonstrate the feasibility and effectiveness of the proposed method.
