About this book


The book showcases cutting-edge concepts and methods, and presents the principle of imprecise-information processing. It also proposes a new theory and technology for imprecise-information processing that differs from fuzzy technology, thus providing a platform for related applications and laying the theoretical basis for further research.

Imprecise-information processing – a type of processing based on flexible linguistic values and quantifiable rigid linguistic values – is an important component of intelligence science and technology. This book offers an easy-to-understand overview of the basic principles and methods of imprecise-information processing, allowing readers to develop related applications or pursue further research.

“This research monograph is devoted to so-called flexible concepts (flexible sets) aimed at the representation and processing imprecision in systems analysis. … the book could be of interest to various groups of readers as offering yet another avenue of representing and processing imprecise information.” (Witold Pedrycz, zbMATH 1370.68006, 2017)
