Wire ropes are used for different applications in many industrial domains, for instance, lifting system. Depending on the conditions of use, wire ropes are being degraded with direct consequences are significant changes of geometric and mechanical characteristics of its components. This results in a reduction in the resistance capacity of the wire rope with time, which could bring failure. Two parameters are susceptible to depict this degradation: a continuous variable which is damage and a statistical variable which is reliability. Our work consists of studying the impact of the breaking of the wires which constitute the wire ropes on its duration. For that we will establish a model that will allow us to connect the two parameters (Damage and reliability) and we will thus broaden this link to the case of compound systems. We are equally proposing to develop a new model which permits providing the reliability of a wire rope in multiple levels of damage of its components. The method adopted is a multi-scale approach with a total decoupling between the scale of the wire and the wire rope.
