Special Issue Information

Dear Colleagues,

Electro-mechanical systems have become increasingly favored due to their significant advantages such as their low noise, flexibility and convenient maintenance. The ability of electro-mechanical systems for fault diagnosis and reliability analysis is very important, especially for various forms of safety-oriented equipment. Advanced sensing technologies are important prerequisites for fault diagnosis and reliability analysis. This Special Issue aims to highlight research into novel sensors and sensing methods, data processing and sensor fusion, and typical applications for fault diagnosis and reliability analysis with elector-mechanical systems.

The goal of this Special Issue is to provide a platform for interdisciplinary research that bridges the gap between sensor technologies, sensing methods, and intelligent fault diagnosis systems, enabling the rapid development of reliability and safety technologies for electro-mechanical systems.

Potential topics of interest include, but are not limited to, the following:

  • Design and manufacturing of precision sensors for electro-mechanical systems;
  • Active and passive sensing methods for electro-mechanical systems;
  • Advanced signal processing and data processing for electro-mechanical systems;
  • Sensor fusion techniques for electro-mechanical systems;
  • Fault diagnosis methods for electro-mechanical systems;
  • Reliability analysis methods for electro-mechanical systems.

In modern aerospace systems, effective sensor optimisation is essential for ensuring reliable diagnostics, efficient resource allocation, and proactive maintenance. This paper presents Normalised Diagnostic Contribution Index (NDCI) integration into the Multi-Objective Sensor Optimisation Framework (MOSOF) to address application-specific performance nuances. Building on previous work, the proposed approach leverages a multi-objective genetic algorithm to optimise key criteria, including performance, cost, reliability management, and compatibility. NDCI is derived from simulation data obtained via the Boeing 737-800 Environmental Control System (ECS) using the SESAC platform, where degradation level readings across four fault modes are analysed. The framework evaluates sensor performance from the perspectives of Original Equipment Manufacturers (OEM), Airlines, and Maintenance Repair Overhaul (MRO) organisations. Validation against the Minimum Redundancy Maximum Relevance (mRMR) method highlights the distinct advantage of NDCI by identifying an optimal set of three sensors compared to mRMR’s six-sensor solution, and MOSOF’s multi-objective insertion enhances sensor deployment for different stakeholders. This integration not only expands the feasible solution space for sensor-pair configurations but also emphasises diagnostic value over redundancy. Overall, the enhanced NDCI-MOSOF offers a scalable, multi-stakeholder approach for next-generation sensor optimisation and predictive maintenance in complex aerospace systems. The results demonstrate significant improvements in diagnostics efficiency for stakeholders. Full article
