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 ...

Multisource Interval Data Fusion and Reliability Analysis for Avionics Products

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
In the reliability analysis process of high‐reliability and long‐life avionics products, constrained by time and economic costs, as well as sparse point data, interval data from multiple sources can usually be obtained. To address this, a multisource interval data fusion method based on value measurement is proposed.
