As along with Information Technology industry developing, innovating and constantly researching on processing, the application of the High-pressure Air has already occupied quite an important position in its field. It is a main course that High-pressure Air manufactures will face the issues of the prompt increasing requests from the strong demand of market year after year. They also have to find a good solution of how to effectively integrate their internal process flow, so as to reduce the cost of production and promote the efficiency of business management for achieving a highly competitive advantage of marketing. Therefore, we deeply research for the High-pressure Air filling operation and hard try to look for some key points could break through the bottleneck of management High-pressure Air cylinder and diagnose for cylinder management. Then we can workout a proposal of process improvement combined with a system assessment which is a program system of evaluating managing for the cylinder information from customer requests. For High-pressure Air filling industry, the manufactures could set up the program system as an important reference of cylinder management.
