This paper introduces an algorithm for the detection of change-points and identification corresponding subsequences in transient multivariate time-series data (MTSD). The analysis such has become increasingly important due to growing availability many industrial fields. Labeling, sorting or filtering highly measurement training Condition-based Maintenance (CbM) models is cumbersome error-prone....

In most industries, such as aerospace, manufacturing, transport and energy sectors, maintenance plays a vital role in improving the performance of safety critical equipment facilities. It also helps industries achieve largest possible efficiency, ensure workplace environmental safety, reduce unnecessary breakdowns costs. Therefore, it is crucial for to adopt an optimal strategy their systems in...

Wind energy has emerged as a highly promising source of renewable in recent times. However, wind turbines regularly suffer from operational inconsistencies, leading to significant costs and challenges operations maintenance (O&M). Condition-based monitoring (CBM) performance assessment/analysis are vital aspects for ensuring efficient O&M planning cost minimisation. Data-driven decision making ...

One of the prevalent issues in condition based maintenance (CBM) is to predict the residual life of the equipment. This paper proposes a novel framework to predict the remnant life of the equipment, called Residual life prediction based on optimally parameterized Wavelet transform and Mute-step Support vector regression (RWMS). In optimally parameterized wavelet transform, a generalized criteri...

Integrated system health monitoring and management (ISHM) is a field of research and development where both academia and industry is highly focused on. Airbus Defence & Space has recognized that simulation is a key capability for developing ISHM technologies and is therefore in the process of developing a comprehensive simulation framework in that area. One significant building block is to invi...

The area of asset maintenance is becoming increasingly important as greater asset availability is demanded. This is evident in increasingly automated and more tightly integrated production systems as well as in service contracts where the provider is contracted to provide high levels of availability. Simulation techniques are able to model complex systems such as those involving maintenance and...

In power energy distribution networks, switchgear is considered critical equipment. This because the act of monitoring operation and condition switchgear, as well performing required corrective maintenance on any potentially problematic equipment, critical. A single event may harm thousands customers over time pose a significant risk to operational staff. Many considerations must be put in plac...

Technical Data Analysis (TDA) presents the architecture development of its rotary wing dynamic component structural life tracking system, HeloTrack.net, which was developed for the US Navy to meet Condition Based Maintenance (CBM) objectives. Methods of fatigue lifing are discussed in the context of improving accuracy for end of life predictions of rotary wing fleets. TDA improves on the curren...

In the recent years, manufacturing companies are investing in sensors and information systems to implement condition-based maintenance (CBM), thus pursuing benefits of digital transformation. Nevertheless, CBM as advanced system, significant investment should be made gather manage all needed data from different sources; besides, qualified human resources required for analytics. Given this premi...

The success of a Case Based Reasoning (CBR) system depends on the quality of case data and the speed of the retrieval process that can be expensive in time especially when the number of cases gets large. To guarantee this quality, maintenance the contents of a case base becomes necessarily. As a result, the research area of Case Base Maintenance (CBM) has drawn more and more attention to CBR sy...
