Factor space theory in fuzzy information processing—Composition of states of factors and multifactorial decision making

The concept of factor space used in fuzzy information processing is investigated. The composition of the states of factors, which is a basic tool in multifactorial decision making, is first considered. Then, a general model of multifactorial decision making is formulated. Finally, multi-factorial decision making with multiple objectives is introduced. Numerical examples are given to illustrate the approaches.
