【摘要】：随着我国军队装备现代化进程的不断推进,信息化成为军工制造企业发展的必然趋势。协同制造执行系统是在传统MES基础上结合协同思想发展而来的下一代车间生产管理系统,是企业实现信息化协同制造的重要一环。因此,如何有效地构建满足军工离散企业需求的c-MES系统,是重要且有待深入研究的课题。本文在分析了c-MES系统的发展及国内外研究现状的基础上,对c-MES系统进行了需求分析,构建了面向军工离散企业的协同制造执行系统体系结构,并通过UML建模建立了软件系统的功能模型。研究了基于c-MES系统的多车间协同计划与调度技术,结合军工离散企业计划特点和调度问题分类,建立了多车间计划调度流程,并以此为依据设计了面向多车间协同作业的协同遗传算法,通过算例运算验证了算法的有效性,进而对c-MES软件系统计划与调度子系统进行了详细设计。研究了基于c-MES的生产数据采集与处理技术,通过分析车间生产数据类型及其采集方式,设计了多车间生产数据采集方案,结合c-MES总体体系结构建立了数据采集与处理子系统的软件结构体系,并对多车间生产数据进行了统一分类和建模,保证了各个车间信息源的一致性,进而对数据采集与处理子系统进行了详细设计。在完成以上关键技术研究的基础上,通过运用数据库、.NET、Web Service等相关技术,结合应用企业对系统的实际需求,开发了协同制造执行系统,并通过运行实例验证了系统在实际应用中的有效性与可行性。
[Abstract]:With the development of military equipment modernization, informatization has become an inevitable trend in the development of military manufacturing enterprises. Collaborative manufacturing execution system is the next generation workshop production management system developed on the basis of the traditional mes combined with the cooperative thought. It is an important part of the enterprise to realize the information collaborative manufacturing. Therefore, how to effectively construct c-MES system to meet the needs of discrete military enterprises is an important subject to be further studied. Based on the analysis of the development of c-MES system and the current research situation at home and abroad, the requirements of c-MES system are analyzed. The architecture of collaborative manufacturing execution system for military discrete enterprises is constructed, and the function model of software system is established by UML modeling. The cooperative scheduling and scheduling technology based on c-MES system is studied. Combined with the characteristics of military discrete enterprises and the classification of scheduling problems, the scheduling process of multi-shop planning is established. Based on this, a collaborative genetic algorithm for multi-shop cooperative jobs is designed. The effectiveness of the algorithm is verified by an example, and then the planning and scheduling subsystem of c-MES software system is designed in detail. The production data acquisition and processing technology based on c-MES is studied. The multi-workshop production data acquisition scheme is designed by analyzing the production data types and their collection methods. Combined with the overall architecture of c-MES, the software architecture of data acquisition and processing subsystem is established, and the unified classification and modeling of multi-workshop production data are carried out to ensure the consistency of information sources in each workshop. Then the data acquisition and processing subsystem is designed in detail. On the basis of the research of the above key technologies, through the application of database, net Web Service and other related technologies, combined with the actual needs of the application enterprise to the system, A collaborative manufacturing execution system is developed, and the effectiveness and feasibility of the system in practical application are verified by a running example.
