非串行CIMS生产线可靠性建模、分析与综合

采用等效工作站方法,对非串行CIMS生产线可靠性进行了研究,得到了一条缓冲库可 用度的定理,并推导出在稳态情况下,非串行CIMS系统(如装配线和拆卸线)可以转变成串 行系统求解.同时分析出加工过程不丢失工件的充要条件和若干必要条件,绘出一幅PK-K 曲线,可以给出可行解的大致范围,有助于具体问题的求解.

Modeling,Analysis and Synthesis of the Reliability of Non-Series CIMS Production Line

This paper studies the reliability of non-series CIMS production line. By usingthe method of an equivalent workstation, a theorem on availability of buffers is proposed. In steady state, a non-series CIMS system, such as an assembly line and disassembly line, can be solved through transformation into a series system. Additionally, analysis of a sufficient condition and several necessary conditions for not losing any workpieces during operation is given. Finally the curve of Pk-K is shownto hint the probable scope of available solution to a real problem.
