Statistic And Analysis System For Cold Roller Production-Design And Implementation Of Quality Evaluation And Information Management

With the rapid development of iron and steel industry, market competition in cold roller product has been increasingly brutal as a large consumption of it. The core competitiveness of cold roller is shown in product quality and management level, cold roll enterprises must be focus on their own supplier management and product user satisfaction except improving their technology of manufacture and quality level. Good suppliers and clients management can help enterprises select high-quality materials, improve quality and provide better sevices for users.This research topic is relied on "Statistic and Analysis System for Cold Roller" of Shanxi Baiyi Machinery Equipment Cold Roll factory. This object design and implement Statistic and Analysis System for Cold Roller based on process data management system by actual research and software project idea.Quality evaluation subsystem and information management module is a important part of it.First of all, the paper summarizes the basic methods and principles of system evaluation, anylazes impact factors of cold roller suppliers evaluation, establishes index system of roll suppliers evaluation; anylazes impact factors of roll product user satisfaction, establishes index system of roll product user satisfaction; proposes functional requirements model and the data needs models of quality evaluation subsystem and information management module based on user’s actual demand of quality evaluation and information management analysis; complete function structure design, database design and interface design of quality evaluation subsystem and information management on the basis. At last it implements quality evaluation subsystem and information management module.Quality evaluation subsystem including evaluation platform management module, roll supplier evaluation module and roll product user satisfaction evaluation module.Now, the system is running in actual manufacture and quality management of BaiYi company. Through this system, it can help evaluate cole roller supplier’s level, select better suppliers and improve quality of raw materials.Also,it can help company find shortcoming of product and service to improve product quality and service level for user satisfaction and market share.
