This paper presents an assessment of the state of practice in prognostics and health management of information and electronics-rich systems. While there are two general methods of performing PHM̶modelbased and data-driven methods̶these methods by themselves have some key disadvantages. This paper presents a fusion prognostics approach, which combines or “fuses together” the model-based and datadriven approaches, to enable markedly better prognosis of remaining useful life. A case study of a printed circuit card assembly is given in order to illustrate the implementation of the fusion approach to prognostics.
