Abstract

Reliability is a systemic and multidimensional characteristic, i.e. it is a characteristic linked to the context. The dimensions defining it are of various natures: from one side there is the dimension of a cognitive phenomenon - the probability - from the other side there are dimensions of physical phenomena. The systemic and multidimensional nature of reliability raises unusual problems of measurement. For some attributes of a product, it is not easy to find measures that allow ratio scale or interval scale. For certainty, additive probability as measure is also doubtful in many practical cases. So we could have a reliability based on probability measure and a reliability based on fuzzy measures. The problem of the measure adopted is further complicated when reliability is not estimated directly with reference to an indivisible item but is computed by means of a decomposition and recomposition of a system. This is the case of all complex apparatus. The paper put in evidence the current trends in tackling these problems.
