Preventive Maintenance Analysis Based on Mean Time Between Failure (MTBF) and Mean Time to Repair (MTTR)

Angkasa: Jurnal Ilmiah Bidang Teknologi, 2023
A company's ability to meet its goals depends heavily on the smooth operation of its production process. To ensure that the production machinery operates smoothly and without any breakdowns, it is essential to implement effective maintenance that addresses any issues related to the equipment.

Digital‐Twin‐Enabled, Time‐Aware Anomaly Detection for Industrial Cyber‐Physical Systems

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
The graphical abstract (Graphical Abstract figure) summarises the proposed pipeline: multivariate ICS data streams are windowed and normalised, fed into a temporal LSTM–DNN encoder and per‐sensor operating‐envelope learner, combined via calibrated fusion and finally surfaced through an operator‐facing digital twin that provides event timelines, top ...

Multiple Radios for Fast Rendezvous in Heterogeneous Cognitive Radio Networks

IEEE Access, 2019
In cognitive radio networks (CRNs), if two unlicensed secondary users (SUs) want to communicate with each other, they need to rendezvous with each other on the same channel at the same time.

Identification of Critical Machine in Textile Industry Using Reliability‐Centred Maintenance and Failure Mode and Effects Analysis—A Case Study of Bahir Dar Textile's Share Company

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
The study aims to mitigate these risks through the implementation of a structured RCM policy. The findings indicate that the machines in the spinning section are the most critical in terms of their failure impact. Implementing the RCM methodology demonstrates significant economic benefits by reducing risk through a targeted FMEA approach.

Real Availability Index for Energy Hubs: A Novel Monte Carlo–Markov Hybrid Approach for Comprehensive Reliability and Economic Analysis Incorporating Dynamic Demand Profiles in High‐Rise Residential Buildings

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper conducted a unique availability and economic analysis of two energy hubs (EHs) with different capacities (2 MW and 900 kW). The proposed EH supplies the electricity and heat requirements of a high‐rise residential complex in Tehran. A new index called real availability was introduced and implemented, integrating hourly demand profiles and ...

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 ...
