This book mainly introduces rough set theory and its continuation in the incomplete information system (IIS). Rough set theory is a mathematical theory used for dealing with imprecise problems; its a significant development of the classical set theory. Since rough set theory is based on the equivalence relation, it cant be used to deal with IIS with unknown attribute value. As a result, how to expand relevant concepts of rough set in the IIS is of crucial significance to the development of rough set. This book introduces the latest research findings; it includes basic concepts of rough set theory, IIS with unknown attribute value and the relevant expansion model, rough model and attributes reduction in neighborhood system and IIS, order relation and rough set model in IIS, as well as generalized rough set model in multi-valued information system and inter-value information system, etc.

Incomplete Information System and Rough Set Theory: Models and the Attribute Re-ductions provides evidence of the present growth in the rough set approach to the incom-plete information system at The topics discussed in this book have received significant attentions in recent years because researchers can apply new tools for problem solv-ing. This book reflects a number of approaches those were either directly or indirectly begun by the semi. Bookseller Inventory # N15190
