Abstract: Abstract Residual life estimation plays a significant role in scheduling maintenance activities for high-reliability products. In the literature, most of the existing studies dealt with this issue by considering only one-dimensional performance characteristic. However, it may be unreasonable since a product can have multiple performance characteristics. Generally, these performance characteristics are dependent due to the common influences from the environments. Moreover, the nonlinearity of the product’s degradation process should also be taken into account. In this chapter, degradation models based on nonlinear Wiener process is presented to address the issue under univariate and multivariate situations. Based on the proposed method, a closed-form of the probability density function (PDF) of the product’s residual life can be approximately obtained. Numerical examples concerning fatigue cracks demonstrate the validity of the proposed method.
