Fuzzy Availability Computation of Semi-Markovian Mechatronic System Using Hybrid Approach

摘要

This paper presents availability computation procedure of a semi-Markovian mechatronic system under the uncertainties that involve randomness as well as fuzziness. Conversion of semi-Markov to Markov model is stated first and hybrid approach is then used for fuzzy availability computation. Sometimes statistical data is available about failure and repair rates, but in cases where such data is scarce or not available, one has to rely on subjective information or judgment provided by the expert. As a result, the problem in which some data is probabilistic and some is of fuzzy nature is resolved in this paper using the hybrid approach.
