This paper reviews a few studies related to the usage of model-fitting methods in reliability assessment and prognostic framework. The reviewed studies consider prediction of a time-to-failure value given a deterministic degradation model and a set of data obtained from accelerated testing or/and operational use. Different types of regression models are implemented to evaluate remaining useful life of a component or system. Essentially, the evaluation of remaining useful life is performed through extrapolation of a deterministic trend found in the degradation data. To effectively use the model-fitting methods one has to made strong assumptions regarding the underlying degradation mechanism.
