Abstract(in English) | Reliability importance of a component in a system is defined as the rate that the system reliability changes by changing the component's reliability and the reliability importance of a network system is called marginal reliability importance(MRI). This paper deals with the problem to compute MRI for all components in a network system, named CCMRI(Complete Computation for MRI). Hsu et. al. proposed an efficient algorithm using some network reductions for CCMRI where two-terminal reliability is adopted as network reliability. Their algorithm can be applied to the only networks whose reliability can be computed in a polynomial time by the network reductions. This paper proposes an algorithm for CCMRI which can be applied to any network topologies where all-terminal reliability is adopted. Numerical experiments have shown that the proposed algorithm can reduce computational time for CCMRI to approximately 20% of that of a traditional method when near neighbor graph is selected as target network topology. |
