The Defect and Improvement of Traditional Lean Production

Bared on a summary of the Conventional lean production theory, this paper points out some defects of the production mode:theoretirally valuing too much of eliminating wastes, while practically only conantrating on parts;unable to meet the quichly-changed market;lack of tool to analyze complicate problems. So some suggestion are forward: new lean-views should be established; decoupling point and delaying technology are keys to integrate lean production and agile manufacturing, lean production should be integrated with six sigma when deal with complicated problems.
