Lifecycle Option Selection in Early Design Stages Based on Degradation Model Evaluation
Published online by Cambridge University Press: 26 May 2022
Abstract
Components of modern systems are characterised by differing lifetimes. The resulting lifetime heterogeneity (LTH) is a core criteria to determine life cycle options (LCO) for more sustainable products, e.g. by upgrading or reuse. Estimating the lifetimes is challenged by a lack of suitable degradation models (DM) describing the detrimental change performance of components during the use phase. This paper expands the state of the art in LCO selection by a method to evaluate fitness and sensitivity of DM based on the similarity of use cases, environments and operation profiles of the system.
