Robust Remanufacturing Planning with Parameter Uncertainty
Zhicheng Zhu, Yisha Xiang, Ming Zhao +1
We consider the problem of remanufacturing planning in the presence of statistical estimation errors. Determining the optimal remanufacturing timing, first and foremost, requires m…
Health Assessment and Prognostics Based on Higher Order Hidden Semi-Markov Models
Ying Liao, Yisha Xiang, Min Wang
This paper presents a new and flexible prognostics framework based on a higher order hidden semi-Markov model (HOHSMM) for systems or components with unobservable health states and…
Multi-component Maintenance Optimization: A Stochastic Programming Approach
Zhicheng Zhu, Yisha Xiang, Bo Zeng
Maintenance optimization has been extensively studied in the past decades. However, most of the existing maintenance models focus on single-component systems and are not applicable…
Condition-based Maintenance for Multi-component Systems:Modeling, Structural Properties, and Algorithms
Zhicheng Zhu, Yisha Xiang
Condition-based maintenance (CBM) is an effective maintenance strategy to improve system performance while lowering operating and maintenance costs. Real-world systems typically co…
