Abstract EN
With the increasing complexity of industrial products and systems, some intermediate states, other than the traditional two states, are often encountered during reliability assessments.
A system with more than two states is called a multistate system (MSS) which has already become a general phenomenon in the components and/or systems.
Moreover, common cause failure (CCF) often plays a very important role in the assessment of system reliability.
A method is proposed to assess the reliability and sensitivity of an MSS with CCF.
Some components are not only in a failure state that can cause failure itself, but also in a state that can cause the failure of other components with a certain probability.
The components that are affected by one type of CCF make up some sets which can overlap on some components.
Using the technology of a universal generating function (UGF), the CCF of a component can be incorporated in the expression of its UGF.
Consequently, indices of reliability can be calculated based on the UGF expression of an MSS.
Sensitivity analysis can help engineers to judge which type of CCF should be eliminated first under various resource limitations.
Examples illustrate and validate this method.
