【摘要】：随着加入WTO以后市场竞争的日趋激烈,我国制造企业不仅面临着提高企业生产率的重任,而且需要全面提升企业竞争力,对企业实施信息化管理成为各类企业的普遍需要。于是每个企业都在寻求较好的生产与运作管理方案,以提高企业的生产、经营和管理效率,从而提高企业的核心竞争优势。而生产与运作管理的核心是生产作业调度问题能否高效地获得优化解,因此,研究生产作监调度问题具有很大的理论意义和现实价值。生产调度系统是一个综合的职能部门,它是企业的生产指挥中心,对生产活动中的各工序、各环节进行系统的控制与协调。在传统的制造企业生产调度系统中存在着一些问题,如在调度过程中缺乏必要的现场信息,而控制层也不能及时将生产过程中可能发生或已经发生的脱离计划的偏差信息反映给计划层。制造执行系统(MES)其定义为:“位于上层的计划管理系统与底层的生产控制之间的面向车间层的管理信息系统”。它建立了以生产作业管理为中心的计算机辅助车间管理信息系统,能够很好地解决上述所存在问题。MES将来自企业计划层的计划信息转化为指令下发到生产控制层,并从生产控制层中获得生产实绩数据,向计划层及时地提供生产实际状况信息。本论文以企业控制系统集成S95标准为方法和基础。简要介绍了MES的概念及S95标准之后依据S95标准分析了MES中的计划调度活动,并依此建立了装饰布企业计划调度活动的活动模型,分析了计划调度活动的相关信息,详细论述了生产能力信息。之后分析了装饰布企业生产的特点以及存在的问题,提出车间作业调度具体方案。在分析车间作业调度内容的基础上,提出了装饰布企业生产模式下工序级作业调度与设备组内作业分配相结合的分层调度模型,分别介绍两个层次调度的目标与规则的选取以及算法步骤。最后通过企业中的实例,验证了该方法的可行性。
[Abstract]:With the increasingly fierce market competition after China's entry into WTO, Chinese manufacturing enterprises are not only faced with the task of improving the productivity of enterprises, but also need to enhance the overall competitiveness of enterprises. The implementation of information management for enterprises has become a common need of all kinds of enterprises, so each enterprise is looking for a better plan of production and operation management in order to improve the efficiency of production, management and management. Therefore, the core of production and operation management is whether or not the production scheduling problem can be solved efficiently, so, It is of great theoretical significance and practical value to study the problem of production supervision and scheduling. Production scheduling system is a comprehensive functional department. There are some problems in the traditional production scheduling system of manufacturing enterprises, such as the lack of necessary field information in the process of scheduling. The control layer can not reflect the deviation information which may occur or has occurred in the production process to the planning layer. Manufacturing execution system (mes) is defined as "Shop level oriented Management Information system (SMIs) located between the planning management system at the upper level and the production control at the bottom", which establishes a computer-aided workshop management information system with production job management as the center. Mes can well solve the above problems. Mes transforms the plan information from the enterprise planning layer into instructions to the production control layer, and obtains the production performance data from the production control layer, and provides the production actual status information to the plan layer in time. This paper is based on the S95 standard of enterprise control system integration, introduces the concept of MES and the S95 standard, then analyzes the planning and scheduling activities in MES according to S95 standard. Based on this, the activity model of planning and scheduling activities of decorative cloth enterprises is established, and the related information of planning and scheduling activities is analyzed, and the information of production capacity is discussed in detail. Then, the characteristics and problems of production of decorative cloth enterprises are analyzed. On the basis of analyzing the content of job shop scheduling, a hierarchical scheduling model combining process level job scheduling and equipment group job assignment is proposed in the production mode of decorative cloth enterprises. The selection of targets and rules and the steps of the algorithm are introduced respectively. Finally, the feasibility of this method is verified by an example in an enterprise.
