Abstract

This paper discusses the semi-markovian approach for availability modeling of a deteriorating system under fuzziness. The case presented here is of repairable mechatronic system & a four state semi-markov model for such a system is developed. The semi-markov model is converted to markov model and fuzzy availability is found out assuming five linguistic variables with triangular membership functions allocated to all failure & repair rates.
