Abstract: Aiming at the problem that the goal weight with reasonable and actual physical meaning was difficult to determine in green process decision,a decision making method of process schema was proposed for green manufacturing based on decision maker's preference and mutual feedback.Through refining user layer,preference capture layer,decision making layer,schema evaluation layer and alternative schema layer,the multi-layer architecture for process green analysis was realized.The fuzzy linguistic knowledge of green manufacturing was quantified by fuzzy set theory.According to the acquired preference information for decision objective,the preference functions reflected maker's subjective idea were built,and a physical programming decision model of green satisfied process schema was constructed under fuzzy context.Through the preference information feedback between decision maker and selected process schema,the process schema evaluation for green manufacturing based on fuzzy physical programming model and mutual feedback was completed.The proposed method was applied to green process schema selection of automobile parts,and the results indicated that it could avoid the requirement of given meaningless weighing factor and greatly improve the analysis satisfaction.

Key words: fuzzy physical programming, green manufacturing, process scheme decision making, mutual feedback
