Reliability Analysis Based on Crosstabulation: A Novel Method

By choosing the critical components, the maintenance and service operations can be directed to the most relevant parts of a facility or a process. Traditionally in definition of critical components reliability techniques, such as fault mode effect analysis, fault mode effect and criticality analysis or fault tree analysis, have been used. The disadvantage of these methods is laborious of the analysis and deficient available statistic data. The determination of critical components can be carried out by new reliability analysis method developed by VTT Technical Research Centre of Finland, which is based on the self-evaluation by the operation personnel and crosstabulation of the affecting factors in a similar manner as a decision matrix.
