计算机集成制造系统中的可靠性

 <正> 1.引言 计算机集成制造(CIM)技术十分适合于小批量生产,有助于提高产品质量和生产效率,计算机集成制造系统(CIMS)就是采用CIM技术的生产系统,它是在柔性制造技术、计算机技术、信息技术和系统科学的基础上将工厂生产经营活动所需的各种自动化系统有机地集成起来;它能根据竞争市场的需求运用于多种中小批量产品生产,获得高效率、高柔性的智能生产系统。

RELIABILITY ASPECTS IN COMPUTER INTGRATED MANUFACTURING SYSTEMS

Computer Integrated Manufacturing System (CIMS)has drawn much attention because of its maket-driven flexibility, high productivity and great economic benefit. To deal with the reliability aspects of a CIMS, two issues concerning the modelling and measuring its reliability behavior as well as the assuring and enhancing its reliability must be considered. A brief introduction to a CIMS for Flight Control System (PCS) is made and twelve measures to assure the reliability of this FCS-CIMS are proposed. On the other hand, since a CIMS is generally degradabel, the system cannot be simply determined as fully functioning or fully failed and thus fuzzy approach should be used to model the system reliability behavior. It is further argued that profust availability should be taken as the quantitative reliability index for the FCS-CIMS and how to do profust availability allocations is discussed.
