A clear and practice-oriented reference on multi-criteria decision-making, with a well-articulated connection to complementary approaches such as multi-objective optimization. Highly relevant for process engineering, energy systems, and sustainability applications, the book is well suited for undergraduate and graduate (Master’s and PhD) education, as well as engineering practice. The combination of sound theoretical foundations, illustrative numerical examples, and accessible software tools makes it a particularly effective resource for both learning and practical implementation.Dr. Catherine Azzaro-Pantel, Professor in Chemical Engineering, Université de Toulouse, Institut National Polytechnique de Toulouse, FranceThrough the integration of illustrative programs, worked examples, and sound theoretical principles, this book presents a coherent approach to multi-criteria decision-making. Its emphasis on practical usability makes it a valuable reference for advanced students and practitioners working in complex engineering and decision-analysis problems.Dr. Christopher Teoh, Assistant Professor, DigiPen Institute of Technology SingaporeThis book offers a really clear and well-organized look at multi-criteria decision-making (MCDM). What I liked most is how it bridges the gap between complex theories and how they actually work in the real world.Instead of just focusing on abstract concepts, it uses helpful numerical examples and computational methods that make the material much easier to grasp. Whether you are a student or a professional, this is a practical and accessible guide that shows you exactly how to apply these methods to solve real problems.Dr. Sayed Ameenuddin Irfan, Director (Data and AI), UpGradThis forthcoming book by Professors Rangaiah and Wang offers a clear, comprehensive, and practice-oriented introduction to multicriteria decision‑making (MCDM), a methodology that has become essential across engineering, science, and technology. Beginning with real-world examples, from catalyst selection to renewable energy evaluation, the authors present MCDM as a rigorous yet accessible framework for navigating complex decisions involving multiple, often conflicting criteria. Their use of the CAUSE (Criteria, Alternatives, Uncertainties, Stakeholders, Environmental factors) framework and a step-by-step MCDM workflow gives readers a strong conceptual foundation while emphasizing the importance of transparency, systematic analysis, and informed judgment.The book stands out for its balance of theory, algorithms, and practical tools. Dedicated chapters cover multi-objective optimization, normalization techniques, objective and subjective weighting methods, and a broad suite of ranking approaches, all supported by examples and ready-to-use software in Excel and Python. Its modular structure makes it ideal both as a textbook and as a reference for practitioners. With its strong engineering orientation, particularly relevant to chemical engineering, process design, sustainability assessment, and materials selection, this volume promises to become a key resource for students, educators, researchers, and professionals seeking robust, modern decision-making methods.Jules Thibault, Department of Chemical and Biological Engineering, University of Ottawa, Canada
