Smart applications are transforming conventional supply chains into digital ones. To compete in today’s competitive market, organizations must utilize the merits of the Fourth Industrial Revolution while being sustainable, lean, and eco-conscious. Smart and Sustainable Operations and Supply Chain Management in Industry 4.0 closes the gap and provides novel ideas, research, and applications. This book discusses smart and sustainable supply chain management concepts that are analyzed within the Industry 4.0 perspective. It also highlights green systems and smart applications within an Industry 4.0 setting. The book presents the latest technological developments, including disruptive technologies and their impact on smart and sustainable supply chains under the triple bottom line approach. For easy reader comprehension, each chapter will include a case study, a related problem, or a numerical example, as well as the solution. This book is written for academicians, practitioners, PhD students, and researchers involved in this area.

This book presents a holistic view on localized energy transition while addressing current challenges associated with the production of biofuels, introducing new materials to produce solar photovoltaic (PV) panels, and digital systems for sustainable energy monitoring on a small scale, carbon capture, and sequestration. Also, each chapter of the book addresses specific aspects of the renewable and sustainable energy space while focusing more on energy improvement and storage technologies that are practical focused. Features: Offers useful information on new forms of renewable energy generation with reference to Industry 4.0. Illustrates practical approaches to energy transition. Provides guidance on renewable energy sources and energy storage systems. Discusses the application of the Fourth Industrial Revolution (4IR)-related approaches to emerging energy storage technologies. Includes studies that reveal approaches to realizing productivity, profitability, and increased return on investment (ROI). This book is aimed at graduate students and researchers in mechanical, chemical, and mechatronics engineering and renewable energy systems.
