【摘要】：目前,国内多数大型制造企业,特别是资产密集型企业,由于设备维护与管理不当导致企业生产需求与设备资产资源之间产生的矛盾日趋突出,在相当程度上影响了企业的生产效率和竞争力。建立设备健康维护信息系统,实现设备维护与管理信息化是解决这一冲突的有效途径之一。但在面对复杂信息系统时,由于缺乏对系统建模等的关注,往往造成信息孤岛、不能准确获取和表达系统需求等大量问题。本文针对大型制造企业复杂信息系统,提出了基于IDEF、UML和Petri网相融合的IUP集成建模方法。IUP综合了IDEF方法进行需求建模语义精确和容易理解、UML方法面向对象设计及对编程实现支持良好、Petri网方法具有动态分析能力的特性,重点研究了IDEF、 UML、Petri网的形式化定义和三者之间相互转换的映射规则,提高模型转换时的精确性和效率。将IUP建模方法应用于广西华锡集团的设备健康维护信息系统,结果证明IUP方法能为复杂系统建模提供了一套切实可行、高效率的建模方法。根据大型制造企业备件管理需求,提出了备件ABCD分类法及其库存控制策略。研究了(R,s,S)策略下的单点存储最小缺货模型,以及采用仓库批量订货及库存点转运策略下的两级多点存储模式最优库存模型。以华锡集团为例,证明了模型能优化库存,实用性强。依据B/S/D模式,采用Oracle lOg作为数据库,Oracle Forms Developer做为编程开发工具,Oracle Reports Developer作为报表开发工具,编程实现了华锡集团设备管理信息系统。系统具有流程为主导,财务为中心,成本控制为主线,系统高度集成等特点。系统现已在华锡集团得到广泛应用。
[Abstract]:At present, most large manufacturing enterprises in China, especially the capital intensive enterprises, because of the improper maintenance and management of equipment, the contradiction between enterprise production demand and equipment assets resources is becoming increasingly prominent. To a certain extent, it affects the production efficiency and competitiveness of enterprises. It is one of the effective ways to solve this conflict to establish equipment health maintenance information system and realize equipment maintenance and management information. But in the face of complex information system, Due to the lack of attention to system modeling, there are many problems, such as information isolated island, unable to accurately obtain and express system requirements and so on. This paper aims at the complex information system of large manufacturing enterprises, This paper presents an integrated modeling method of IUP based on IDEFN and Petri nets. It integrates the IDEF method for requirement modeling with precise semantics and easy to understand the object-oriented design of IDEF method and has the ability of dynamic analysis to support the programming implementation. The formal definition of IDEFand UML Petri nets and the mapping rules between them are studied in order to improve the accuracy and efficiency of model transformation. The IUP modeling method is applied to the equipment health maintenance information system of Guangxi Huaxi Group. The results show that IUP method can provide a set of practical and efficient modeling methods for complex system modeling. According to the requirements of spare parts management in large manufacturing enterprises, this paper puts forward the ABCD classification of spare parts and its inventory control strategy. And the optimal inventory model of two-stage multi-point storage model under the strategy of warehouse batch ordering and inventory point transshipment. Taking Huaxin Group as an example, it is proved that the model can optimize inventory and has strong practicability. According to the B / S / D model, Oracle lOg is used as the programming tool of Oracle Forms Developer as the report development tool, and the equipment management information system of Huaxin Group is programmed and realized. The system is process-oriented and financial as the center. Cost control is the main line and the system is highly integrated. The system has been widely used in Huaxin Group.
