“…The utilization of solar energy is a prominent feature of Indian Railways' climate change adaptation strategy. Solar panels have been installed on railway station rooftops, railway buildings, and other infrastructure to generate renewable energy and reduce reliance on conventional power sources [57]. This initiative not only reduces carbon emissions but also helps in energy cost savings.…”

This study delves into the crucial task of embedding climate change resilience within the sphere of railway infrastructure planning and design in India. As climate change continues to threaten global transportation systems, the creation of robust, sustainable infrastructure becomes indispensable for minimizing its impacts. Initial investigation entails assessing both existing and anticipated climate change scenarios in India, encompassing elements like temperature fluctuations, changes in precipitation, and severe weather phenomena. Following this, the study proceeds to pinpoint the specific risks and vulnerabilities that the Indian railway system stands to confront due to these climatic shifts. A thorough exploration of current adaptation policies and strategies provides a framework to merge these into railway infrastructure planning and design, using a mix of literary review, best practices, and international case studies as resources. The Indian railway network undergoes a meticulous analysis to evaluate its vulnerability, leading to the identification of key adaptation measures like devising new railway tracks, enhancing the existing infrastructure, adopting resilience-based technologies, and implementing nature-centric solutions. The research probes the economic, social, and environmental ramifications of these measures, underlining the long-term sustainability and beneficial impacts on the transportation industry. Expert interviews, stakeholder consultations, and policy analysis culminate in a set of recommendations for policymakers, urban planners, and transportation authorities. These recommendations aim to shape the progression of a climate-resilient railway infrastructure in the light of India's distinct challenges. Such an integration of climate change adaptation strategies contributes towards a more robust and sustainable transportation system. This study enriches the existing body of knowledge on climate change adaptation in transportation, offering valuable perspectives for policymakers, practitioners, and researchers aiming for climate resilience in the railway sector.

“…Özelikle optimizasyon problemlerinin çözümünde, farklı alanlardaki problemlere kolayca uyarlanabilen sezgisel algoritmalar tercih edilmektedir. Doğadaki canlılardan, fizik ve kimya yasalarından esinlenerek geliştirilen bu algoritmalar; solar yakıt hücrelerinin tasarımı (Ajayan, 2022), motorların başarımının artırımı (Duan ve diğ., 2023), güç sistemlerinin iyileştirilmesi (Ali ve diğ., 2023), tıp alanında hastalık teşhisi (Riaz ve diğ., 2022), yapay sinir ağlarının eğitimi (Öztürk ve diğ., 2018; Mardani-Aghabaglou ve diğ., 2021), akım ve gerilim sensörlerinin tasarımı (Raheem ve Basil, 2023), elektrik ağlarının planlanması (Xia ve diğ., 2023) gibi birçok alanda yaygın bir şekilde kullanılmaktadır. Sezgisel algoritmalar rastgele arama süreçleri kullandıklarından, gradyan tabanlı optimizasyon tekniklerine göre daha çok sayıda hesaplama girişimine ihtiyaç duymaktadırlar.…”

Bu çalışmada ilk olarak, betonarme sürekli kirişlerin detaylı tasarımlarının minimum maliyetle yapılabileceği bir süreç tasarlanmıştır. Ardından bu problem üzerinde FDB-TLABC, TLABC, TLBO ve ABC algoritmalarının performansları değerlendirilmiştir. Bu amaçlarla öncelikle Türk betonarme standardı ve deprem yönetmeliği dikkate alınarak optimizasyon problemi oluşturulmuştur. Bir, iki ve üç açıklıklı kiriş örneklerinden oluşan bir problem takımı hazırlanmıştır. Bu problem takımı üzerinde yapılan testlerden algoritmaların optimum sonuca ulaşma performansları ile belirlenen makul çözümlere ulaşma süreleri ve başarıları belirlenmiştir. Optimum sonuca ulaşmada, TLABC ve FDB-TLABC algoritmalarının en başarılı algoritmalar olduğu görülmüştür. Kararlılık analizinden, TLABC algoritmasının en yüksek kararlılığa ve hıza sahip olduğu görülmüştür.

“…The optimization-based methodology for using particle swarm optimization for a fuel cell battery hybrid locomotive is proposed in [20]. There are, additionally, numerous different investigations on EMS, evaluating the hybrid framework such as the methodology dependent on Pontryagin's minimum principle [21,22], Metaheuristic optimization techniques [23], fluffy rationale control [24], speed trajectory optimization by Improved Pathfinder algorithm [25], least identical hydrogen consumption [26], etc. However, the majority of these EMSs are presented for simple and low-power road vehicles and are not specified for large-scale, high-power, and time-varying rail vehicles.…”

As one of the most environmentally friendly energy sources today, fuel cells have become the focus of research in countries around the world, especially in the electric transportation field. This paper mainly studies the modeling of fuel cell hybrid locomotives (FCHL) including fuel cells, batteries, motors, and energy management systems. To increase the operating efficiency and improve the performance of FCHL, a modified fuzzy logic-based energy management system (MFL-EMS) is proposed and compared with the traditional power flow energy management system (PF-EMS). Meanwhile, a modified fuel cell hybrid power system model for locomotives is proposed, taking into account the traction motor features that, compared with a simplified controlled source load, can directly reflect the status of the locomotive running speed and the output power of the traction motor load. The proposed system parameters and configurations are determined by combining the characteristics of power and energy density, response characteristics, and charging/discharging characteristics of fuel cells and batteries. The precise simulation results revealed that adopting the proposed MFL-EMS in comparison to the traditional PF-EMS, reduced the hydrogen consumption by 2.943%. Comparing the battery output voltage, it is confirmed that with MFL-EMS it tends to be steeper than the one with PF-EMS, showing the proposed strategy’s robustness. Overall, the obtained results revealed an improved performance in terms of power distribution as well as SOC, which means less hydrogen consumption and therefore a more economical solution.
