Reengineering method of production system based on theory of constraint and system dynamics

JIA Guo-zhu,CHENG Yang(Sch.of Economics & Management,Beihang Univ.,Beijing100083,China)  
The Theory of Constraint(TOC) and System Dynamics(SD) were introduced into the reengineering process of production systems,and a method of production system reengineering based on TOC and SD was proposed.This method emphasized the importance of human factor by means of improving modeling methods for production systems,and it also overcame the problems caused by constraints transfer by using problem-solving tree,resource-using tree and constraint transfer matrix.The idea of Total Constraint Management(TCM) was also brought forward through the extension of the TOC.TCM provided a new perspective of awareness and managing the constraints in production systems,and the constraints were regarded as the objects of management.The objective of TCM was to enhance the effectiveness and efficiency of production systems by establishing a mechanism for supervision,prevision and management of constraints.Finally,a case study was used to validate the method.
