Economic Replacement of Plants and Equipment: A Decision-Making Framework in Engineering

Advances in Science, Technology and Engineering Systems Journal, Volume 10, Issue 5, Page # 20–32, 2025; DOI: 10.25046/aj100503
Abstract:

While prior research has focused on siloed approaches to equipment replacement, this study introduces an integrated decision-making framework that synergizes predictive maintenance (IoT/M), dynamic multi-criteria analysis (MCDM), and sustainability-driven material selection. By validating this model through cross-sector case studies and strategic operational planning across various industrial sectors. We demonstrate a 30% improvement in replacement timing…

Investigating the Optical Behavior of Single/Multi-Dimensional Photonic Crystal Structures for Photovoltaic Applications

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 951–958, 2020; DOI: 10.25046/aj0506113
Abstract:

The results investigated in this work are toward the optimization of the photonic crystal structures in 1D and 2D scale. One-dimensional distributed Bragg reflectors (DBRs) have demonstrated substantial potential in various optoelectronic applications, due to the observed tunable optical band-gap. Herein, the use of DBRs in light trapping solar cells was simulated and validated, representing…
