【摘要】 制造执行系统(Manufacturing Execution System，MES)是实现制造业信息化的核心技术之一。MES是面向车间层的生产管理技术与实时信息系统，它位于企业上层的企业资源计划(ERP)和底层设备自动控制系统(通常称为过程级自动控制系统，即Process Control System，PCS)之间，强调制造计划的执行能力。刀具是机械制造过程中的一个极为重要资源，据统计，直接的刀具费用通常占制造总成本的5％，刀具的保管、准备、重磨及供应管理等费用往往高达12％，随着数控机床的普及，这个比率还会大大增长。因此，刀具的合理使用及其管理水平不仅直接关系到制造成本，而且将直接影响制造系统的执行能力。然而，现有的ERP系统忽视了企业对刀具的需求分析、合理使用与科学管理等问题，传统ERP系统中的库存理论与库存模型研究都未涉及工具库存模型。综上所述，本课题的主要研究工作与贡献在于：1、分析研究了现有ERP／MES／PCS三层架构、分系统功能及其相互作用，构造面向MES的刀具管理系统总体框架。2、基于面向对象技术和UML建模工具，分析研究了ERP／MES／PCS环境下，刀具管理系统的主要功能及其开发环境。3、研究了CAPP系统、现场数据采集系统和质量管理系统环境下，刀具编码系统、刀具组装中的自动编码方法、刀具基本信息的存储模型、基于支持向量机的刀具耐用度预测方法等。4、构造和实现了面向CAPP、现场数据采集和质量管理等系统的刀具管理系统核心模块，其中包括：刀具基本信息管理模块、刀具自动配置模块和刀具耐用度预测模块等。更多还原

【Abstract】 Manufacturing Execution System (MES) is one of key techniques. It is the real-time MIS and production management techniques originated for workshop. The status of the MES which emphasizes the ability of execution about the manufacture planning is between ERP and rock-bottom Process Control System (PCS).The tool is a kind of important resource in the manufacture process. The cost of tool usually account for 5% in the total cost. And the cost of the storing, preparation, regrinding and so on reaches to 12% usually. With the popularization of the numerical control machines, the rate will be developed more. So, the reasonable utilization of the tool and the level of the management not only impact the cost of manufacture, but also influence the ability of the execution about MES.However, current ERP ignored the analysis of the requirement, reasonable utilization and scientific management for tool about enterprise. And the storage theory and the research about storage model in the past ERP didn’t involve storage model for tool. To sum up the above arguments, the main contributions of this thesis include:1. Research the three layer structure, the function of the child system and relation about the current ERP/MES/PCS and construct an overall framework of the system originated for MES.2. The overall function of the tool management system is researched with the techniques of OOP (Object Oriented Programming) and modeling tool with UML.3. The coding system, the storage model of the tool and the method to forecast the life of tool based on SVM are researched in the environment of CAPP, sport data collection System and quality management System.4. The kernel modules of the tool management system which include modules of essential information management about tool, modules of tool’s automatic configuration, modules to forecast the life of the tool are contrived based on CAPP, spot data collection System and quality management system.更多还原
