Article Citation - Scopus: 49EdgeAISim: A Toolkit for Simulation and Modelling of AI Models in Edge Computing Environments(Elsevier Ltd, 2024-02) Nandhakumar, Aadharsh Roshan; Baranwal, Ayush; Choudhary, Priyanshukumar; Golec, Muhammed; Gill, Sukhpal SinghTo meet next-generation Internet of Things (IoT) application demands, edge computing moves processing power and storage closer to the network edge to minimize latency and bandwidth utilization. Edge computing is becoming increasingly popular as a result of these benefits, but it comes with challenges such as managing resources efficiently. Researchers are utilising Artificial Intelligence (AI) models to solve the challenge of resource management in edge computing systems. However, existing simulation tools are only concerned with typical resource management policies, not the adoption and implementation of AI models for resource management, especially. Consequently, researchers continue to face significant challenges, making it hard and time-consuming to use AI models when designing novel resource management policies for edge computing with existing simulation tools. To overcome these issues, we propose a lightweight Python-based toolkit called EdgeAISim for the simulation and modelling of AI models for designing resource management policies in edge computing environments. In EdgeAISim, we extended the basic components of the EdgeSimPy framework and developed new AI-based simulation models for task scheduling, energy management, service migration, network flow scheduling, and mobility support for edge computing environments. In EdgeAISim, we have utilized advanced AI models such as Multi-Armed Bandit with Upper Confidence Bound, Deep Q-Networks, Deep Q-Networks with Graphical Neural Network, and Actor-Critic Network to optimize power usage while efficiently managing task migration within the edge computing environment. The performance of these proposed models of EdgeAISim is compared with the baseline, which uses a worst-fit algorithm-based resource management policy in different settings. Experimental results indicate that EdgeAISim exhibits a substantial reduction in power consumption, highlighting the compelling success of power optimization strategies in EdgeAISim. The development of EdgeAISim represents a promising step towards sustainable edge computing, providing eco-friendly and energy-efficient solutions that facilitate efficient task management in edge environments for different large-scale scenarios. © 2023 Elsevier B.V., All rights reserved.Article Citation - WoS: 13Citation - Scopus: 16Ecological Footprints and Sustainable Environmental Management: A Critical View of China's Economy(Academic Press Ltd- Elsevier Science Ltd, 2023-12) Li, Menghan; Badeeb, Ramez Abubakr; Dogan, Eyup; Gu, Xiao; Zhang, HongGlobal economies have recently been concerned about sustainable environmental management by reducing emissions and tackling ecological footprints. The rapid economic expansion and investment in traditional manufacturing further raises environmental degradation. China surpasses other emerging economies in the economic growth race yet has remained the top pollution-emitting economy for the last few decades, necessitating scholarly attention. This study examines the influencing factors of ecological footprints in China from the perspective of COP27. Using the extended dataset from 1988 to 2021, this study uses several time series diagnostic tests and verifies the existence of the long-run association between the study variables. Consequently, the non-linear scattered data leads to non-parametric (method of moment quantile regression) adoption. The empirical results indicate that only economic growth is a significant factor in environmental quality degradation in China. However, improving renewable energy usage, research and development, and foreign direct investment reduces the country's ecological footprint. Hence, the latter variables substantially lead to environmental sustainability. The robustness of the results is confirmed via a robust non-parametric estimator and causality test. Based on the empirical results, this study recommends increased investment in research and development, renewable production, and foreign direct investment enhancement.Article Citation - WoS: 12Citation - Scopus: 18A Comparison of Proactive and Reactive Environmental Strategies in Green Product Innovation(Inderscience Publishers, 2019) Genç, Ebru; Di Benedetto, C. Anthony; Anthony Di Benedetto, C.Companies are exposed to different kinds of pressures to respond to environmental sustainability issues. It is critical to understand how firms integrate environmental issues into their corporate agendas and how these integration strategies affect corporate performance. This paper investigates factors that motivate firms to adopt environmental marketing strategies and their relative impact on green product innovation performance. A comprehensive conceptual framework is developed and tested that portrays the antecedents and consequences of environmental marketing strategy (EMS). The results show that developing environmental strategies that exceed regulations (proactive strategies) leads to better new product performance than those that only adhere to regulations (reactive strategies). In addition, we find that commitment from top management becomes critical only for proactive strategies, not for reactive strategies. Finally, with regard to the consequences, we show that environmental marketing strategies lead to new product advantage and, ultimately, improved sustainable new product performance. © 2021 Elsevier B.V., All rights reserved.
