Evaluation of fuzzy reliability of a non-series parallel network

Abstract It is well known that conventional reliability analysis using probabilities has been found to be inadequate to handle uncertainty of failure data and modelling. To overcome this problem, the concept of “fuzzy probability” has been used in the evaluation of reliability of a general non-series parallel network. Basically, only two operations, i.e. multiplication and complementation, need to be performed in assessing system reliability of a non-series parallel system. A procedure is developed to carry out these operations efficiently.
