MULTI-STATE SYSTEM ANALYSIS BASED ON MULTIPLE-VALUED DECISION DIAGRAM

Mathematical description of an examined system like a Multi-State System (MSS)permits the analysis of this system reliability in more detail, because the MSS defines someperformance levels (more that only working and failure). A structure function is one of basicdefinitions of MSS. But the structure function dimension increases critically depending on thenumber of system components. Therefore the development of methods for examination andquantification of such function is an actual problem in MSS reliability analysis. In this paper amethod for the analysis of the MSS structure function with high dimension is proposed. Thismethod is based on initial representation of the MSS structure function by Multiple-ValuedDecision Diagram and is developed for calculation of the importance measures of the MSS.
