Optimal condition-based maintenance strategy under periodic inspections for traction motor insulations

Condition-based maintenance under performance-based contracting

Condition Based Preventive Maintenance Control Strategy Design

Compared with time based maintenance (TBM), Condition based maintenance (CBM) can improved the availability of the devices and reduced the examining maintenance cost. However, CBM possibly arouse an unexpected interference on production process due to an unplanned maintenance activity in advance so that the stable-state operation of the system was influenced. As the system scale was larger, thi...

A condition-based maintenance policy and input parameters estimation for deteriorating systems under periodic inspection

We study the problem of proposing Condition-Based Maintenance policies for machines and equipments. Our approach combines an optimization model and input parameters estimation from empirical data. The system deterioration is described by discrete states ordered from the state “as good as new” to the state “completely failed”. At each periodic inspection, whose outcome might not be accurate, a d...

Optimal Condition-based Maintenance Decision Making for a Cluster Tool

In semiconductor fabrication, dynamic interactions among chamber deterioration, operation characteristics, and wafer yield necessitate an intelligent decision making policy for maintenance. However, only simple heuristic rules for maintenance scheduling are currently employed in semiconductor fabs. Therefore, there is a clear need for a more formal framework for maintenance decision making. The...

Application of Multivariate Control Charts for Condition Based Maintenance

Condition monitoring is the foundation of a condition based maintenance (CBM). To relate the information obtained from the condition monitoring to the actual state of the system, it is usually required a stochastic model. On the other hand, considering the interactions and similarities that exist between CBM and statistical process control (SPC), the integrated models for CBM and SPC have been ...
