Enhancing Resilience in Aerospace and Defense MRO: A FIT2 Gaussian Fuzzy MCDM Framework for Enterprise Blockchain Selection

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Blockchain technology offers transformative potential for enhancing transparency, traceability, and operational resilience in aviation maintenance, repair, and overhaul (MRO). However, a critical research gap exists in evaluating enterprise‐level blockchain adoption within highly regulated, security‐sensitive aerospace and defense (A&D) MRO ecosystems,

Markov‐Driven Reliability Improvement in Duplex and Triplex Standby Architectures With Variable Failure and Repair Rates

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
To enhance the reliability of industrial wireless sensor networks (IWSNs), this study develops a state‐based continuous‐time Markov model for duplex and triplex architectures equipped with warm and cold standby backup sensors. The proposed model explicitly defines the state space, transition structure, and failure–repair dynamics for one, two, and ...

A Systematic AI‐Based Paradigm for Classifying Hybrid Electric Vehicle Spare Parts Using Their Price and Demand

Journal of Engineering, Volume 2026, Issue 1, 2026.
With the rapid growth of the hybrid electric vehicle (HEV) market, stakeholders must refine after‐sales logistics, particularly spare parts (SPs) provisioning. Adequate forecasting of demand and pricing underpins these efforts. This paper presents a feedforward artificial neural network (FF‐ANN) that, drawing on 15 predictor variables, assigns each SP ...

Improving Reliability Over Time in Industrial Wireless Sensor Networks Using AI‐Driven Duplex and Triplex Markov Models With Spare Node Architectures

Journal of Sensors, Volume 2026, Issue 1, 2026.
This paper analyzes the evolution of system reliability in duplex and triplex architectures enhanced with support nodes using a continuous‐time Markov framework. While the structural topology of the systems remains unchanged, the integration of artificial intelligence (AI) dynamically adjusts failure and repair behavior through intelligent warm‐standby

Research on Multidimensional Application Effect Evaluation of Pipeline Fiber‐Optic Early Warning System

Journal of Sensors, Volume 2026, Issue 1, 2026.
Despite the continuous improvement in the technical performance of fiber‐optic early warning systems, their actual application results in preventing third‐party intrusion into oil and gas pipelines are often less than ideal. This issue stems largely from the lack of comprehensive postdeployment evaluation methodologies, making it difficult to identify ...
