Understanding the Analytic Hierarchy Process

Konrad Kułakowski is an Associate Professor and Deputy Head of the Department of Applied Computer Science, Faculty of Electrical Engineering, Automatics, Computer Science and Biomedical Engineering at the AGH University of Science and Technology (AGH UST). He received his Ph.D. and Habilitation in computer science from AGH UST. His research interests are focused on multiple-criteria decision-making methods, including AHP, and their applications, theory and practice of the pairwise comparison method, parallel programming, and algorithms. He serves as a reviewer of many international journals in operational research and computer science. He has organized several special sessions in International Conferences on Computer Science and Operational Research. He has also served as a member of program committees at numerous international IT and OR conferences and meetings.

"In general, the book is useful for specialists in AHP and MCDM techniques, and can be helpful for researchers and practitioners in various problems of decision making."–Technometrics"The Analytic Hierarchy Process (AHP) is one of the best-known methods of multi-criteria decision-making. This method provides a convenient and versatile framework for modelling decision problems, evaluating alternatives and deriving final priorities. Rather than proposing a "best" solution, AHP allows the user to create a ranking of alternatives, then choose the one which is subjectively the most satisfying.Understanding Analytic Hierarchy Process is not only beneficial for undergraduate, graduate, or postgraduate students:, but for the researchers as well in the areas of operations research decision theory linear algebra, interval analysis, and, fuzzy sets. –Jaroslav Ramik, Ph.D., professor of operations research and statistics, School of Business Administration in Karvina, Silesian University in Opava, Czechia"This book is inclusive in the sense that it presents concepts whose relevance goes beyond the AHP. [. . .] It is auspicable and reasonable to expect that this book will also serve as a bridge between different communities. The book has two types of uses. It can be read from front to back by those with no previous knowledge of the AHP and can be seen as a ‘cookbook’, to always keep on your shelf. Each chapter is structured in such a way that makes it a self-standing story which, with some caution on the notation, is also self-contained. [. . . ] I believe that, whatever type of reader you are, this book will help you understand the AHP."–Matteo Brunelli, University of Trento"Dr. Kulakowski is a world-renowned expert in Pairwise Comparisons, a field of growing importance and wide applicability. The Analytic Hierarchy Process is a fundamental approach in this area, and this books collects and examines all the recent developments, applications and ideas, and provides software code to make it even more relevant to the user who wishes to deploy it immediately. I highly recommend this book."–Michael Soltys, Professor & Chair Dept. of Computer Science, California State University Channel Islands
