Condition based maintenance optimization considering multiple objectives
In condition based maintenance (CBM) optimization, the main optimization objectives include maximizing reliability and minimizing maintenance costs, which are often times conflicting to each other. In this work, we develop a physical programming based approach to deal with the multi-objective condition based maintenance optimization problem. Physical programming presents two major advantages: (...
متن کاملDegradation Modeling Using Stochastic Filtering for Systems under Imperfect Maintenance
Wiener process with a linear drift has been extensively studied in degradation modeling, mainly due to the existence of an analytical expression of the first hitting time distribution which permits feasible mathematical developments. However, a fundamental problem related to the stationary Wiener process is that it can only describe linearly drifted diffusion processes. This article is devoted ...
متن کاملA multi-stage stochastic programming for condition-based maintenance with proportional hazards model
Condition-Based Maintenance (CBM) optimization using Proportional Hazards Model (PHM) is a kind of maintenance optimization problem in which inspections of a system relevant to its failure rate depending on the age and value of covariates are performed in time intervals. The general approach for constructing a CBM based on PHM for a system is to minimize a long run average cost per unit of time...
متن کاملOptimal condition-based maintenance decisions for systems with dependent stochastic degradation of components
Components in engineered systems are subjected to stochastic deterioration due to uncertainties in the operating environmental conditions and material properties. The component could be, for example, moving parts such as gear boxes and pumps in a chemical plant or equipment production plant, the pipe segments in oil and gas pipeline system, and the heat transport pipe segment in nuclear power p...
متن کاملCondition-based maintenance optimization considering improving prediction accuracy
Condition based maintenance (CBM) aims to reduce maintenance cost and improve equipment reliability by effectively utilizing condition monitoring and prediction information. It is observed that the prediction accuracy often improves with the increase of the age of the component. In this research, we develop a method to quantify the remaining life prediction uncertainty considering the predictio...
