【Abstract】 There are many complex production problems for the enterprises in the manufacturing process.Whether there are any correlations between these problems,or different problems can be dealt with concurrent lean improvement and how to plan the problem solving have always plagued enterprises.Based on the problem correlation analysis,this paper proposes the concept of problem cluster,and plans the problems on basis of cluster thought and multi-criteria fuzzy group decision theory.Firstly,the self-organizing mapping algorithm(SOM)is proposed to cluster and analyze the problems in the current value stream of the enterprise,to obtain the problem clusters;Then,based on the fuzzy VIKOR group decision method,the problems in the problem clusters are sorted.The problem of highest importance is improved preferentially as the cluster center.The problems of highest importance in different problem clusters are solved with concurrent lean improvement.Finally,the proposed enterprise problem planning method is applied to the lean continuous improvement process of a certain assembly enterprise.The result shows that the method has good application value as it can realize multi-question planning in the manufacturing process of the enterprise.更多还原
