Statistic And Analysis System For Cold Roller Production——Design And Implementation Of Quality Analysis

After so many years of development, most of the manufacturing enterprises have finished the informationization management. However, they only focus on the business process flow management, and don’t effectively use the data. It’s effective for improving the company’s quality and management level to use advanced management tools and the business data. Under the background, BY Company proposed an informationization demand for Statistic and Analysis System for Cold Roller Production.The paper is under the background of actual production of BY Company’s cold roller factory. According to the characteristic of cold roller production process and the database of the original management information system, considering the needs of BY Company, Statistic and Analysis System for Cold Roller Production is designed and developed. The system is running successfully at the BY Company and gets a good result.After on-the-spot investigation of BY Company, company’s needs and problems in production are known, and needs analysis is completed. According to the needs analysis, the primary design plan is made, which decides the function scope of the system. After the communication with the leadership and the technical staff of BY Company about the primary design plan, formulate the detailed design plan and decide the specific function of the system. Update the database of the original management information system to fulfill the data needs of the new system. After the development of Statistic and Analysis System for Cold Roller Production, the system is running at BY Company’s cold roller factory; collect the customers’ feedback, and modify the system.Statistic and Analysis System for Cold Roller Production is composed of three sub-systems:statistic analysis subsystem, quality analysis subsystem, quality evaluation subsystem. In the primary design plan, quality analysis subsystem has six modules:material quality analysis module, supplier quality analysis module, process quality analysis module, device quality analysis module, staff quality analysis module, product quality analysis module. According to the detailed design plan, quality analysis subsystem is merged into three modules:material quality analysis module, process quality analysis module, product quality analysis module. There are total seven analysis tools:histogram, capability indices analysis, control chart, Pareto chart, pie chart, trend chart, comparison chart. Users can analyze the cold roll production from all aspects, find and solve the quality problems and improve the company’s quality level.
