ＣＩＭＳ（计算机集成制造系统）技术的实质是籍助计算机硬件、软件，将企业主要生产过程中有关人、技术和经营管理的要素及其信息流和物流有机地集成并优化运行，以提高企业的生产和工作效率。ＣＩＭＳ由功能分系统和支撑分系统两部分组成，其关键技术主要有面向ＣＩＭＳ的经营管理技术、计算机辅助设计、计算机辅助工艺流程、计算机辅助制造、柔性制造技术和并行工程技术等。ＣＩＭＳ在我国的研究、开发和应用工作从１９８６年３月“８６３”高技术计划启动时开始，１０多年来，走出了一条由信息集成到过程集成到企业集成的道路，从而扩大了ＣＩＭＳ的内涵，提出了更高层次的ＣＩＭＳ的概念，即现代集成制造系统。１９９４年以来，我国已在１０多个省、直辖市的８０多家企业中推应用ＣＩＭＳＩ程，从而提高了企业的经济效益和综合竞争能力。为了更好地推广和交流ＣＩＭＳ技术和经验，有必要建设我国的ＣＩＭＳ信息网络（ＣＩＭＳｎｅｔ）。
The essence of CIMS (Technology of Computer Integrated Manufacturing System) is to assist the computer hardware and software to integrate and optimize the operation of the elements of human, technology and management in the main production process of an enterprise and its information flow and logistics to improve the efficiency of the enterprise Production and work efficiency. CIMS consists of functional subsystems and supporting subsystems. The key technologies are CIMS-oriented management techniques, computer-aided design, computer-aided process, computer-aided manufacturing, flexible manufacturing and parallel engineering. CIMS started its research, development and application in our country from the start of the “863” Hi-Tech Project in March 1986, and out of a process of integration from information into process integration to enterprise integration in the past 10 years, thus expanding the connotation of CIMS , Put forward the concept of higher level CIMS, namely modern integrated manufacturing system. Since 1994, China has applied CIMSI to more than 80 enterprises in more than 10 provinces and municipalities, thus improving the economic efficiency and comprehensive competitiveness of enterprises. In order to promote and exchange CIMS technology and experience better, it is necessary to build CIMSnet of our country.
