Base On Value Stream Map Theory To Optimize Supply Chain Manufacture Process

The dissertation analysis the background of current rapidly changing market environment, and customer require enterprises to improve production efficiency, timeliness and accuracy, then base on the theory of value stream map to analysis value-added and non-value-added process during supply chain activity for customer, using Lean Six Sigma tools and management methods to effectively reduce non-value added, increase the value added to optimize the supply chain management, so it will help to meet customer demand.Firstly, under the current rapid development of economic globalization, and increasing business competition, customer demand for the product is also personalized to the diversification requirements, it lead to company run the production with small batch size and more variety to meet customer’s requirement.Secondly, from the theory of value stream map, combined with other Lean and Six Sigma tools, it explains how to identify value-added processes and non-value-added processes, optimize all aspects of the elimination and reduction of various waste, and enhance the value of speed of information flow, shorten product delivery cycle, thereby increasing the value added process for customers, while reducing non-value added processes, optimize the supply chain management, in order to meet customer timeliness, accuracy needs to improve customer satisfaction. Base on value of the business process flow chart of all related material flow and information flow, to be expressed in a manner shown to help visualize the currently active processes, and based on the observations and analysis, it will help to design future value stream map. Using of PDCA thinking, it reflect a continued improvement ideas.Finally, combined with one actual case of a company, through detail improve activity, and detail data analysis, to show the actual effect to verify the value stream map method to improve the supply chain management. It also show the application vividly that how to use value stream map theory to solve the supply chain problem.
