Abstract

We discuss the interpretation of linguistically quantified statements using fuzzy sets. We indicate that there are two methods of interpreting these statements, the algebraic approach and the substitution approach. We then use quantified statements to express overall decision functions involving multiple objectives. These statements are of the type “A solution should satisfy many of the objectives”. Using the algebraic and substitution approach, we develop a whole family of forms for combining multiple objectives. We show that algebraic approach corresponds to situations in which we are unconcerned about the allocation of satisfaction amongst the objectives but just interested in getting much satisfaction. The substitution approach on the other hand leads to forms which are dependent upon the allocation of satisfaction between the objectives.

    Citation Excerpt :

    For allowing the experts to express the degree of individual criteria importance, it is best to allow decision makers more flexibility to express their attitudes towards certain proportional criteria. The aggregation by classical fuzzy intersection (Bellman & Zadeh, 1970) is not appropriate (Yager, 1983), because the final decision best action of course is strongly required to satisfy ’all’ the criteria. Therefore, the decision makers should allow the experts to express their attitudes as much as “criteria” are needed.

    2019, Information Sciences
    Citation Excerpt :

    Each of the linguistic terms is mapped to a fuzzy quantifier function. Yager [42] pointed out that the aggregation by fuzzy intersection is not appropriate, because the final overall decision is, of course, required to satisfy ‘all’ the criteria. Owing to the complexity of judgments, the hierarchical multiple criteria are mostly satisfied to achieve the final best course of decision-making action.

    Then in Paragraph 2.5, we underline some possible extensions of these works in order to position our contribution. In [4,5], Yager proposes some extensions of Bellman and Zadeh's approach. He defines a decision function as a quantified linguistically proposition.

  • Ranking and selection of unsupervised learning marketing segmentation

    2013, Knowledge-Based Systems
    Citation Excerpt :

    The first approach is to use a learning mechanism using some sample data; the second approach is to provide some semantics or meaning to the weights. The latter approach enables applications in the area of quantifier guided aggregations [64,65]. This type of aggregation ‘is very strongly dependent upon the weighting vector used’ [22], and consequently upon the function expression used to represent the fuzzy linguistic quantifier.
