The States of Buffer and Reliability Analysis on CIMS Production Line
CIMS生产线中缓冲区状态及可靠性分析

The key to the reliability of CIMS production lines is to analyze the states of buffer. When the capacity of buffer increases, the complexity of analyzing the production line increases too. This paper presents the state-simplifying method. First. we analyze the states of the buffer and the work stations, simplify the K+1 states of buffer, whose capacity is K, into three states: "empty", "non-empty, non-full" and "full". Then we discuss the state transition rate under four case of the work stations to get three theorems of the state-simplifying.
