Abstract

Reliability has recently emerged from the quality concept. If quality represents the total of a product's qualities, which make it good for use according to the destination, the reliability represents the capacity of the product to maintain its quality during the entire usage time. Reliability is the quality of the product extended through time. Reliability, maintenance, availability and capacity related aspects have been treated distinctively up to one moment. Analytically, the reliability represents the probability that during a given period of time, a product will be flawless. The technological capability or reliability represents way in which a technological system may realize, on the entire process of fulfilling a mission, the corresponding technological performances for its objectives. A unitary approach, considering all the factors, in accordance to the operating conditions of technical systems, lays the fundaments of an interdisciplinary theory, called the Theory of safety during operation. The safety during operation, S, of a machinery or of a technological system represents the way it will fulfill its mission, being a function of availability A, reliability R, capacity C and maintenance M: S(t) = r[A(t);R(t);C(t);M(T)].
