Industry 4.0 is the fourth industrial revolution where machine operations are linked through data communications and together, they form a production ecosystem. In settings, these monitored, recorded analyzed. This can be performed at Edge, Fog or Cloud levels.
 big era, with ever maturing sensor technologies, capture, communication storage utilizing for operational insights provide...

The fuel system, which aims to provide sufficient the engine maintain thrust and power, is one of most critical systems in aircraft. However, possible degradation modes, such as leakage blockage, can lead component failure, affect performance, even cause serious accidents. As an advanced maintenance strategy, Condition Based Maintenance (CBM) effective coverage, by combining state-of-the-art se...

Abstract When condition-based maintenance (CBM) is combined with proper decision support systems, it leads to enhanced utilization of resources and increased productivity which tends towards business efficiency. The forecasting the future condition, remaining operating life, or probability stable system behavior, based on data from acquired condition monitoring referred as prognosis an importan...

The effectiveness and efficiency of case-based reasoning (CBR) systems depend largely on the success of case-based retrieval. The case-base maintenance (CBM) issues become imperative and important especially for modern societies. This paper proposes a new competence model and a new maintenance procedure for the proposed competence model. Based on the proposed competence maintenance procedure, f...

Case-Base Maintenance (CBM) has two important goals. On the one hand, it aims to reduce the size of the case-base. On the other hand, it has to improve the accuracy of the CBR system. CBM can be represented as a multi-objective optimization problem to achieve both goals. Multi-Objective Evolutionary Algorithms (MOEAs) have been recognised as appropriate techniques for multi-objective optimisati...

The monitoring of condition variables for maintenance purposes is a growing trend amongst researchers and practitioners where decisions are based on degradation levels. two approaches in Condition-Based Maintenance (CBM) diagnosing the level (diagnostics) or predicting when certain will be reached (prognostics). Using diagnostics determines it necessary to perform maintenance, but rarely allows...

For modern semiconductor manufacturing, a large number of interrelated equipment data are automatically collected. These data are usually used for fault detection and classification (FDC). However, unusual measurements may reflect a wafer defect or a change in equipment conditions. Early detection of the equipment condition changes assists with efficient maintenance. This study aimed to develop...

With the increased use of composites in aircraft, many new successful contributions to advancement structural health monitoring (SHM) field for composite aerospace structures have been achieved. Yet its application is still not often seen operational conditions aircraft industry, mostly due a gap between research focus and application, which constraints shift towards improved maintenance strate...

This paper introduces a new ‘Terrain Sensing System’ (TSS) that is able to record the cumulative damage seen by a ground vehicle over its entire operational life. Used within a HUMS IT process, this information can be calibrated to represent directly the residual life of onboard equipment such as electronic control systems, instrumentation, radios, brackets, refrigeration plants and weapons sys...
