Healthcare operations, in hospitals and home healthcare settings, are inundated with complex fuzzy features that impose difficulties in the creation of work schedules. This book presents in-depth research on emerging approaches to healthcare staff scheduling. It starts by reviewing the key issues and challenges inherent in staff scheduling, along with the basic concepts of fuzzy set theory. Examining cutting-edge research applications, it details fuzzy optimization algorithms derived from biologically inspired approaches and fuzzy theory. Facilitating a practical and in-depth understanding of modern fuzzy metaheuristic optimization approaches, the book presents recent research on multi-criteria algorithms and their applications in healthcare operations, particularly staff scheduling.

This book focuses on the application of workstudy in productivity of manufacturing SMEs locally and abroad and also explores various industrial problems which face manufacturing SMEs in developing and underdeveloped countries in the rest of the world. Low productivity is currently a serious challenge facing manufacturing SMEs, where these SMEs are operating below expected production output levels which makes it difficult for them to compete in the global market. SMEs are the engine drivers of economic growth, one of which is manufacturing.The challenge is that government from various countries in developing and underdeveloped countries, mandated agencies in their respective areas, to ensure that there is economic progress for these SMEs, but productivity remains low in the manufacturing SMEs. When SMEs do not perform well, productivity of manufacturing SMEs declines and unemployment increases. Thus, an increase in unemployment results in a drop of GDP in the country and can become a global and economic crisis. This book describes a process which enables the reader to use effective knowledge that addresses problems facing the productivity of manufacturing SMEs such as work study tools and case studies and provides solutions and applications to improve the running of the manufacturing SMEs in growing their productivity.

Energizing Waste: The Circularity Way explores innovative waste-to-energy (WtE) solutions that transform non-recyclable waste into clean energy while reducing operational costs. Featuring ReGen technology, which delivers 332 kW of net energy per ton of waste at a cost of under $1/kWh with a 6–8-year payback period, the book is grounded in the 10Rs principles of circular economy. It establishes strong linkages among waste-to-energy (WtE), environmental quality (EQ), and sustainable development (SD), offering scalable, evidence-based strategies for stakeholders to advance circular economy practices.Key features include:Examine the paradigm shift from a linear to a circular economy, minimizing environmental impacts and resource waste through increased efficiency across all stages of the value chainPresents a novel plug-and-play, climate-smart, energy-independent modular power generation system called Renewable Energy Recovery Generation (ReGen)Advances circularity through practical applications of waste materials, extension of product lifespans, and smarter product design, use, and manufacturingExplores a multidimensional and transdisciplinary approach linking environmental, economic, and social dimensions of the United Nations Sustainable Development Goals (SDGs)Integrates circular economy technologies, resource and energy assessments, and socio-economic analyses with innovative WtE technology design concepts, alongside evaluated resource and energy useThis book is intended for researchers, graduate students, and professionals in environmental engineering, waste management, climate studies, and related fields.

Water, energy, and food are basic requirements for life, and this book presents solutions for obtaining these from sewage wastewater treatment plants. It describes the optimal recovery of value-added products from municipal sewage plants in developing countries, and explains how the plants’ operations can become both economical and sustainable. Further, it shows how the clean effluent that is obtained is then suitable for agricultural use in the production of bio-fertilizers, and graywater for irrigation, and how the recovered biogas could be used for energy and heating needs. Practical case studies from three separate sewage plants are presented to illustrate the processes involved.

This book explores effective environmental impact mitigation for petroleum-based lubricants to reduce their negative persistence during usage and upon end-of-life disposal. The book reviews the basic tribology of lubricants as well as initiatives that may enhance the environmental and economic effectiveness of lubricating oils from the composition design perspective across industries. Considering the blending, application, and disposal of petroleum lubricants in a holistic manner, the book presents and extends current best practices that minimize or eliminate adverse environmental impact throughout the product’s life cycle. The book reviews methods including: raw material substitution, minimizing oil losses during and after manufacturing, raw material and energy consumption reduction, and environmentally friendly applications of oil disposal as ways forward for cleaner and more effective production.This book provides readers with strategies for incorporating cleaner production practices into their operations – a benefit to both environmental legal compliance and business competitiveness – all the while preserving the environment for sustainable development. The book is therefore of interest to both manufacturers and consumers in the lubricants industry.

This book presents advances and innovations in grouping genetic algorithms, enriched with new and unique heuristic optimization techniques. These algorithms are specially designed for solving industrial grouping problems where system entities are to be partitioned or clustered into efficient groups according to a set of guiding decision criteria. Examples of such problems are: vehicle routing problems, team formation problems, timetabling problems, assembly line balancing, group maintenance planning, modular design, and task assignment. A wide range of industrial grouping problems, drawn from diverse fields such as logistics, supply chain management, project management, manufacturing systems, engineering design and healthcare, are presented. Typical complex industrial grouping problems, with multiple decision criteria and constraints, are clearly described using illustrative diagrams and formulations. The problems are mapped into a common group structure that can conveniently be used as an input scheme to specific variants of grouping genetic algorithms. Unique heuristic grouping techniques are developed to handle grouping problems efficiently and effectively. Illustrative examples and computational results are presented in tables and graphs to demonstrate the efficiency and effectiveness of the algorithms.Researchers, decision analysts, software developers, and graduate students from various disciplines will find this in-depth reader-friendly exposition of advances and applications of grouping genetic algorithms an interesting, informative and valuable resource.
