Abstract: 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.

Key words: CIMS, flight control system, reliability
