This paper presents a simulation study for military land equipment operational availability (OA). A discrete event simulation model was developed within this study to support the analysis of the effect of several maintenance regimes on OA namely Corrective Maintenance (CM), Scheduled Preventive Maintenance (SPM), and Condition-Based Maintenance (CBM). The model was implemented using the ARENA e...

This paper presents an overview of two maintenance techniques widely discussed in the literature: timebased maintenance (TBM) and condition-based maintenance (CBM). The paper discusses how the TBM and CBM techniques work toward maintenance decision making. Recent research articles covering the application of each technique are reviewed. The paper then compares the challenges of implementing eac...

In recent years, technological development to shift from conventional time-based maintenance (TBM) condition-based (CBM) has been progressing. response this trend, various efforts are being made for signalling equipment along railway tracks. However, there issues be solved when applying CBM electronic of which indications deterioration is difficult detected. Focusing on the environment in insta...

Condition Based Maintenance (CBM) aims at regulating maintenance scheduling based on data analyses and system condition monitoring. Clear advantages of optimizing maintenance scheduling include relevant cost savings and improved safety and plant availability. A critical aspect is the integration of CBM strategies with condition monitoring technologies for handling a wide range of information so...

An optimization method for condition based maintenance (CBM) of aircraft fleet considering prognostics uncertainty is proposed. The CBM and dispatch process of aircraft fleet is analyzed first, and the alternative strategy sets for single aircraft are given. Then, the optimization problem of fleet CBM with lower maintenance cost and dispatch risk is translated to the combinatorial optimization ...

Department of Industrial Engineering, Tel Aviv University, Ramat Aviv, Israel ABSTRACT Condition-based maintenance (CBM) is increasingly applied to operational systems to reduce lifecycle costs. Predicting the performance of various CBM policies is a challenging task addressed in this work. We suggest a CBM framework that is based on system simulations and a targeted Bayesian network model. Sim...

Improving maintenance scheduling has become an area of crucial importance in recent years. Condition-based maintenance (CBM) has started to move away from scheduled maintenance by providing an indication of the likelihood of failure. Improving the timing of maintenance based on this information to maintain high reliability without resorting to over-maintenance remains, however, a problem. In th...

These days, the extension of reactor operation periods and plant life extension is the worldwide trend for efficient and economical operation of nuclear power plants. Plant maintenance methods have been changing from the traditional time-based maintenance (TBM) or periodical shutdown maintenance (where reactor operation is stopped and all the equipment is checked, disassembled, tested, and asse...

The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...

Condition-based maintenance (CBM) presently plays an important role in avoiding unexpected failures, improving machine reliability, and providing accurate maintenance records and activities for rotating machinery. Traditional wired sensors commonly used for gathering data are costly and of limited value in industry. Recently, together with the advancement of sensor technology and communication ...
