【摘要】：对于制造企业来说,车间是企业信息流、工作流、物料流和控制流的交汇点,是确保生产计划顺利完成的关键机构,在企业生产管理系统中占据重要位置。随着企业信息化建设的不断推进,信息技术已被广泛应用在企业的生产管理中,但由于离散型车间生产过程的复杂和多变,单纯的引入信息技术并不能有效实现生产过程的实时监控,所以如何实现生产过程可视化依旧是企业难以攻克的难题。因此,只有将信息技术的应用与企业的战略、业务和管理相匹配,使管理者能够全面、快速、准确地掌握车间生产情况,及时根据反馈信息来合理分配制造资源和调整生产计划,才能真正提高企业的整体信息化水平,使企业获得最佳的运行效益。首先,论文建立离散型车间生产过程模型,分析了信息和物料在各个工序之间的流动过程;通过对车间生产数据的分类,明确了系统的数据管理类型;结合精益生产理念总结的七大浪费,从约束理论提出的三个基本指标的分解上切入,分析了影响生产系统运行的因素,以此确定了生产过程监控指标体系,完成了系统的需求分析。其次,在需求分析的基础上,对系统的体系结构、功能模型和网络结构进行构建,完成了系统的总体设计。接着,通过对数据采集层的详细设计,提出了基于RFID技术、人工采集和设备终端自动采集三种方式相结合的数据采集方案;通过对数据层的详细设计,完成了系统数据库的概念设计、逻辑设计和具体实现;通过对功能层的详细设计,完成了系统各功能模块的IPO设计;通过对Web服务层的详细设计,利用Web Service技术实现了与ERP系统的集成,完成了对生产系统的闭环控制。最后,采用Microsoft Visual Studio 2010开发软件和C#语言,选用Microsoft SQL Server 2008 R2数据库作为后台数据库,使用ADO.NET数据接口技术和GDI+图形设备接口技术等,开发了离散型车间生产过程监控管理系统。该系统实现了生产过程可视化,使管理者能够实时准确地掌握车间生产情况,对企业进行信息化建设具有一定的参考价值。
[Abstract]:For manufacturing enterprises, the workshop is the intersection of enterprise information flow, workflow, material flow and control flow, and is the key organization to ensure the smooth completion of production plan. Information technology has been widely used in the production management of enterprises, but due to the complexity and variability of discrete workshop production process, with the continuous promotion of enterprise information construction, information technology has been widely used in the production management system of enterprises. The introduction of information technology alone can not effectively realize the real-time monitoring of the production process, so how to realize the visualization of the production process is still a difficult problem for the enterprise. Therefore, only the application of information technology and the strategy of the enterprise, The matching of business and management enables managers to master workshop production situation comprehensively, quickly and accurately, allocate manufacturing resources and adjust production plans according to feedback information in a timely manner, so as to truly improve the overall information level of enterprises. First of all, the paper establishes a discrete workshop production process model, analyzes the flow of information and materials between the various processes, through the classification of workshop production data, This paper defines the data management types of the system, analyzes the factors that affect the operation of the production system by analyzing the decomposition of the three basic indexes proposed by the constraint theory, and combining the seven wastes summarized by the lean production concept. Secondly, based on the requirement analysis, the system architecture, function model and network structure are constructed, and the overall design of the system is completed. Through the detailed design of the data acquisition layer, a data acquisition scheme based on RFID technology, manual acquisition and automatic acquisition of equipment terminal is proposed, and the conceptual design of the system database is completed through the detailed design of the data layer. Through the detailed design of the function layer, the IPO design of each function module of the system is completed, and the integration with the ERP system is realized by using the Web Service technology through the detailed design of the Web service layer. The closed-loop control of the production system is completed. Finally, Microsoft Visual Studio 2010 is used to develop software and C # language, Microsoft SQL Server 2008 R2 database is used as backstage database, ADO.NET data interface technology and GDI graphic equipment interface technology are used, etc. A discrete workshop production process monitoring and management system is developed, which realizes the visualization of production process, enables managers to grasp the workshop production situation in real time and accurately, and has a certain reference value for the information construction of enterprises.
