TL;DR: A system subject to two typical failure modes, degradation-based failure and sudden failure is studied to jointly optimize the replacement interval, monitoring interval and reliability criterion such that the expected cost per unit time is minimized.

TL;DR: An improved Wiener process model is proposed for RUL prediction, in which both drift and diffusion parameters are adaptive with the updating of monitoring data, and the quantitative relationship between degradation rate and degradation variation is considered.

TL;DR: In this article, a weather-centered opportunistic maintenance policy is developed to enable a flexible maintenance resource allocation, and the net revenue of wind turbines is evaluated using the performance-based contracting (PBC).

TL;DR: In this paper, a realistic reliability model for mutually dependent competing failure processes due to degradation and random shocks is presented. And a numerical example of Micro-Electro-Mechanical System (MEMS) is conducted to illustrate the implementation and effectiveness of the proposed model.

TL;DR: This paper proposes a preventive maintenance policy for a single-unit system whose failure has two competing and dependent causes, i.e., internal deterioration and sudden shocks such that the expected cost per unit time is minimized.
