Aggregation Functions
Aggregation is the process of combining several numerical values into a single representative value, and an aggregation function performs this operation. These functions arise wherever aggregating information is important: applied and pure mathematics (probability, statistics, decision theory, functional equations), operations research, computer science, and many applied fields (economics and finance, pattern recognition and image processing, data fusion, etc.). This is a comprehensive, rigorous and self-contained exposition of aggregation functions. Classes of aggregation functions covered include triangular norms and conorms, copulas, means and averages, and those based on nonadditive integrals. The properties of each method, as well as their interpretation and analysis, are studied in depth, together with construction methods and practical identification methods. Special attention is given to the nature of scales on which values to be aggregated are defined (ordinal, interval, ratio, bipolar). It is an ideal introduction for graduate students and a unique resource for researchers.
- Up-to-date and complete survey on aggregation functions
- Presents a unified view of aggregation functions with unified notations and terminology in accordance with mathematical standards
- Essential reference for researchers in a broad range of fields

"The book is very impressive in its scope. The presentation is abstract, formal, and mathematically rigorous, providing a firm foundation for specific applications. This book should be taken very seriously by anyone whose work involves aggregation."
Jonathan Golan, reviews.com
"... it provides a very complete bibliography where applications and more details can be found. I find the book a complete and interesting guide for those who are interested in aggregation operators or need a guide to understand the main aspects of different operators."
