Research on the integration of the methods of enterprise value stream and material flow — Based on the theory of lean production and circular economy

Enterprises are faced with the dual pressures of reducing costs and saving energy and reducing pollution; yet it is entirely possible that the cost and pollution at the same time are cut down through enterprises´ technological innovation and management innovation. Based on this idea, the authors tried to integrate the methods of value stream and material flow, simultaneously identifying and monitoring costs and pollution problems. In the basis of in-depth study up on value stream and material flow, it had been confirmed that the integration of value stream mapping and material flow analysis is necessary and feasible, and the integrated framework of the both had been represented in this paper.
