【摘要】 为了对涟钢各环节进行全面质量管理,及时发现和预测异常,迅速控制和分析质量异常的原因,涟钢拟开发一贯质量管理系统,作为其中的一部分,本文对满足涟钢薄板厂需要的生产过程质量分析系统的开发进行了研究与探讨,对企业质量管理有较好的借鉴意义和推广应用价值。首先本文阐述了生产过程质量分析系统的理论基础SPC(Statistical Process Control)的来源、定义、原理及在国内外的应用情况。在用户需求的基础上确定系统架构为B/S结构,并确定了系统主要组成部分有统计过程分析、趋势分析、符合性分析、质量综合分析、生产事故分析、系统管理等功能模块。其次分别阐述了生产过程质量分析系统中的业务系统设计,系统总体架构设计,系统功能设计,基于ORALCLE9i的数据库设计,输入输出设计。对系统的安全进行了分析设计,在合理选择系统运行的软硬件环境和网络的基础上,从网络、通信、访问控制和数据库采取措施确保系统的安全运行。最后从数据库、WEB应用服务器,底层通信,数据集成方面给出了基于.NET的前后台程序实现了生产过程质量分析系统。本系统成功的关键在于实现了质量信息集成,将存储在异种计算机上的生产过程控制、制造执行、企业管理系统数据自动集成到本系统。重点阐述统计过程分析程序实现和转炉制造执行系统数据集成到本系统的过程。对底层通信的实现、程序清单和运行效果作了介绍。更多还原

【Abstract】 To manage the product’s relevant quality, detect exceptions and analyze causes in time, LianYuan iron&steel corporation planed to develop a Consist Quality Management System(CQMS). As part of the development, Analysis Process Quality System(APQ) which was used by LianGang Strip Production Company, was introduced and discussed deeply. Results and experiences we have got can be conducive for others who engaged in Products Quality Management(PQM).The first part is the origins, definitions, principles and state of the art applications of Statistical Process Control(SPC), which forms the elementary theoretical foundations of APQ. Based on the user requirement we choose a Brower/Server(B/S) architecture, and break the whole work into modules such as Statistical Analysis Modular (SAM), Tendency Analysis Modular(TAM), Condition Sufficient Analysis(CSA), Quality Integrated Analysis(QIA), Production Incident Analysis(PIA), and System Management(SM), etc.In the second part we presented in detail the Business System Design(BSD), the System Integrated Architecture Design(SIAD), the System Function Design(SFD), Oracle Based Database Design(OBDD), Input & Output Design(IOD) of APQ. We have also taken the aspects of security into consideration, by choosing the appropriate software & hardware environment, network, methods of communications and access control of database.In the last part we presented aspects of Web Application Server, Lower Part Communication, Data Integration and realizations based on dot net IDE of APQ. The most important factor that helped our achievement is realization of quality information integration, which integrates combination of production process control, implementation of production and data from product management system into our system. The main part is the realization of the Analysis Program of Statistics Process(APSP) and process of information integration of the Stove Shift Production Execution System(SSPXS). Furthermore, we introduced briefly the implementation of lower part communication and part of the program code and showed the results of program running.更多还原
