ACTA UNIVERSITATIS APULENSIS No 12/2006 ON CHOOSING PROPER LINGUISTIC DESCRIPTION FOR FRACTIONAL FUNCTIONS IN FUZZY OPTIMIZATION
نویسنده
چکیده
When a fractional criterion is to be described by linguistic variables two kinds of approaches are possible: to treat it as a unity (nominator/denominator) and to construct a classic membership function or to aggregate the membership functions separately associated to nominator and denominator respectively. In the paper, two propositions are formulated related to choosing possibilities of aggregation coefficients for fractional criteria’ membership functions and also mathematical model of multiple linear fractional objective programming is analyzed with respect to linguistic variables based solving methods. Computational results are developed in order to highlight theoretical remarks related to membership functions’ for efficiency needed properties.

A new evolutionary technique for multicriteria optimization called Target Hyperplane Evolutionary Algorithm (THEA) is proposed. The originality of the approach consists in the fact that the fitness assignment is realized by using a guiding hyperplane and a new non Pareto optimality concept. THEA has been tested on consecrated benchmarks.

Fuzzy System (FS) and Artificial Neural Networks (ANN) are complementary methods. But while ANN can learn from data FS cannot. Also, Genetic Algorithms (GA) are complementary to FS. While the FS are easy to understand, the GA are not, although they have the ability to learn, and so on. Many researches have been devoted to its fusion. Our purpose is to give a survey of these questions. 2000 Math...
