Quantifiers in the formulation of multiple objective decision functions

General multiple-objective decision functions and linguistically quantified statements

SOME PROCEDURES FOR SELECTING FUZZY SET-THEORETIC OPERATORS

Abstract We investigate the definition of the “and” operation in multivalued logic and decision making. A set of basic properties are suggested. Rules for selecting an appropria...

A LINGUISTIC VARIABLE FOR IMPORTANCE OF FUZZY SETS

In this paper we introduce the concept of a linguistic variable for importance. This is done by defining its linguistic values as fuzzy subsets over the set of nonnegative numbe...

Aggregating evidence using quantified statements

On ordered weighted averaging aggregation operators in multicriteria decisionmaking

The author is primarily concerned with the problem of aggregating multicriteria to form an overall decision function. He introduces a type of operator for aggregation called an ...

Quantified propositions in a linguistic logic

ON THE THEORY OF BAGS

Abstract We introduce the bag structure as a set-like object in which repeated elements are significant. We discuss operations on bags such as intersection, union and addition. ...

Concepts, Theory, and Techniques A NEW METHODOLOGY FOR ORDINAL MULTIOBJECTIVE DECISIONS BASED ON FUZZY SETS

Using the structural forms supplied by fuzzy set theory and approximate reasoning, a new method is presented for solving multiple‐objective decision problems for which the decis...
