First hitting time distribution and cost assessment in a two-unit system with dependent degradation processes subject to imperfect maintenance

Proceedings of the Institution of Mechanical Engineers. Part O, Journal of risk and reliability, 2023
This paper proposes a degradation model for a two-unit series system, where the components exhibit dependence and are subject to imperfect maintenance. The interdependence between both components is captured using the trivariate reduction method.

Optimal control problem of the uncertain second‐order circuit based on first hitting criteria

Mathematical methods in the applied sciences, 2020
First hitting criteria of a system are to initially achieve some performance indeces of the target state set. This paper primarily investigates the optimal control problem of the uncertain second‐order circuit based on first hitting criteria.

Nearly Linear Time Algorithm for Mean Hitting Times of Random Walks on a Graph

Web Search and Data Mining, 2020
For random walks on a graph, the mean hitting time $H_j$ from a vertex i chosen from the stationary distribution to the target vertex j can be used as a measure of importance for vertex j, while the Kemeny constant K is the mean hitting time from a ...

An Age-Dependent Prognostic Model for Nonlinear Degrading Devices Based on Diffusion Process

IEEE Sensors Journal, 2023
Degradation modeling-based remaining useful life (RUL) predicting has become a significant basis of prognotics and system health management (PHM) and has drawn much favor of both scholars and engineers in the field of reliability.

Parameters of stochastic diffusion processes estimated from observations of first-hitting times: Application to the leaky integrate-and-fire neuronal model

Physical Review E, 2007
A theoretical model has to stand the test against the real world to be of any practical use. The first step is to identify parameters in the model estimated from experimental data. In many applications where renewal point data are available, models of first-hitting times of underlying diffusion processes arise.

Low-Mean Hitting Time for Random Walks on Heterogeneous Networks

IEEE Transactions on Information Theory, 2019
Mean hitting time for random walks on a network, defined as the average of hitting times over all possible pairs of nodes, has found a large variety of applications in many areas.

An Adaptive Lévy Process Model for Remaining Useful Life Prediction

IEEE Transactions on Instrumentation and Measurement
Predicting remaining useful life (RUL) is a crucial part of prognostics and health management (PHM), which has attracted widespread attention in academia and industry over the past few decades. Effective estimation of RUL is predicated on the development
