Lessen 15 CIMS The various level of automation in manufacturing operation have been extended further by including increasing information processing functions, utilizing an extensive network of interactive computers. The result is computer-integrated manufacturing, which is a broad term describing the computerized integration of all aspects of design, planning manufacturing , distribution, and management. Computer-integrated manufacturing is a methodology and a goal, rather than an assemblage of equipment and computers .The effectiveness of CIM critically depends on the use of a large-scale integrated communications system involving computers , machines, and their controls. Because CIM ideally should involve the total operation of a company, it must have an extensive database concerning technical and business aspect of the operation. Consequently, if implemented all at once, CIM can be prohibitively expensive, particularly for small-and medium-size companies. Implementation of CIM in existing plants may begin with modules in various phases of the total operation. For new manufacturing plants, on the other hand, comprehensive and long-range strategic planning covering all phase of the operation is essential in order to fully benefit from CIM. Such plants must take in to account the following considerations: ●Availability of financial, technical, and human resources; ●The mission, goals, and culture of the organization; ●Existing as well as emerging technologies in the areas of the products to be manufactured; ●The level of integration desired. 1. Subsystems of CIM Computer-integrated manufacturing systems consist of subsystem that are integrated into a whole. These 15课 计算集成制造 在制造加工操作各种自动化水平通过增加信息处理功能，使用交互式计算机的扩展网络功能，从而得以进一步发展。结果出现里一个广阔的技术领域包括计算机化得设计、制造、计划、营销和管理的计算机集成制造。 计算机集成制造一种方法一个，目标而不是计算机和设备的安装。计算机集成制造的有效性依赖于大规模的集成交流系统包括计算机、机器和它们的控制。理想的CIM一概包括公司所有的运转操作，因此它必须要有设计操作过程的技术和经营上的一个非常大的数据库。准确的说如果这点被实施，CIM高昂的另人承受不起，特别对于那些中小型的公司。 CIM的实施在现有机器设备整个过程的运行不同
