Dynamic Reliability Indices in Reliability Analysis of Multi-State System

Abstract

The reliability of Multi-State System (MSS) is analysed in this paper. In a MSS, both the system and its components may experience more than two reliability states. Many practical and theoretical problems needs still to be solved in this area. One of the crucial ones is to identify how a change in a state of an individual component or changes in states of several ones affect(s) the system reliability. The Multiple-Valued Logic (MVL) tools are employed for handling this problem in this paper. In the paper the structure function and Logical Differential Calculus of MVL function are combined to evaluate the dynamic behaviour of a MSS. The Logical Differential Calculus extends potentialities of structure function tool to analyse also the MSS dynamical properties. The evaluation of MSS components changes is considered in this paper.
