A new modeling framework of component degradation

Abstract : Modeling the degradation process of a component is a fundamental issue for maintenance poli-cy definition. In this work, a degradation model based on the concept of component "effective age‟ is pro-posed. The effective age of a component is treated like a physical variable, indicative of its degradation state, and allows to describe the fact that age may evolve faster or slower than chronological time in adverse or fa-vorable working conditions, respectively. Under this concept, the objective of degradation modeling becomes the identification of the relations between the environmental and operating conditions of the component and its effective age. In particular, the proposed degradation modeling paradigm is thought to be applied to the situation, very common in practice, in which the only available information to build the model is that elicited from experts. The proposed modeling framework is applied to a real case study of a medium voltage test net-work.
