RAILWAY CONDITION-BASED MAINTENANCE MODEL WITH STOCHASTIC DETERIORATION

A 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...

Stochastic Renewal Process Model for Condition-Based Maintenance

This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted expected cost rate criterion for optimizing the maintenance policies, which ignores practical implications of discounting of maintenance cost over the life cycle of the syst...

High-Speed Railway Traction Power Supply Equipment Condition-Based Maintenance Decision Model Based on Reliability

Traction power supply equipments are the core part of the high-speed railway, so the maintenance of the power supply system is crucial for the security of the railway. Based on the research on the durable years of the traction power supply equipments, this paper puts forward the model of testing the traction power supply equipments of the reliable high speed railway. Some practical researches h...

High-Speed Railway Traction Power Supply Equipment Condition-Based Maintenance Decision Model Based on Abrasion Analysis

According to abrasion process of machine equipment parts of overhead line system for traction power supply and characters of wear-out failures, considering on factor changes of all kinds of production conditions in practical operation, set permit of abrasion loss in coordinating with normal distribution, and abrasion loss of parts as random variables, and then establish the relation between mai...
