Abstract:

The article considers the problem of the evaluation of systems reliability using statistical data coming from the reliability tests of its elements when the life times of the elements are described by the exponential distribution. It is assumed that these lifetime data may be reported impre­cisely, and that this lack of precision may be described by fuzzy sets. As the direct application of the fuzzy sets methodology leads, in the considered case, to very complicated and time consuming calculations, simple approximations of fuzzy numbers by the shadowed sets introduced by Pedrycz (1998) have been proposed. The proposed methodology may be simply extended to the case of general lifetime probability distributions.
