In Multi-criteria Decision Making (MCDM) problems dealing with qualitative criteria and uncertain information the use of linguistic values is suitable for the experts in order to express their judgments. It is common that the group of experts involved in such problems have different degrees of knowledge about the criteria, so we propose a multi-granular linguistic framework such that each exper...

The aim of the paper is to compare the general risk of the four most important energy chains (coal, nuclear, gas, hydro). Two different multicriteria decision models, the Analytic Hierarchy Process and the PROMETHEE method have been applied. The chosen risk criteria are: severe accidents, terrorism, environmental and health risks, risk of price changes. The first part of the paper discusses the...

Outranking relations are most often built using a concordance-discordance principle. Such relations are, in general, neither transitive nor complete. This is not to say that the concordance-discordance principle does not impose some "structural" restrictions on these relations. We show why this question may be of some importance for analyzing the various techniques designed to build a recommend...

‎ranking fuzzy numbers is generalization of the concepts of order, and class, and so have fundamental applications. moreover, deriving the final efficiency and powerful ranking are helpful to decision makers when solving fuzzy problems. selecting a good ranking method can apply to choosing a desired criterion in a fuzzy environment. there are numerous methods proposed for the ranking of fuzzy n...

This paper proposes a human age estimation method using Ranking SVM method. Given a face image, most previous methods estimate the human age directly. However, the face images from the same age vary so much that it’s really a difficult problem to estimate the human age accurately. In this work, we adopt an alternative way to estimate the human age. First, the rank relationship of the ages is le...

In this paper, a multi-criteria facility location model is represented. The model is meant to support relief organisations to determine the best warehouse location to stock emergency relief supplies in the pre-disaster phase of a natural disaster. As a result of the prepositioning of the goods the relief organisations are able to respond immediately to an occurring disaster. In consideration of...

A meaningful rank as well as efficient methods for computing such a rank are necessary in many areas of applications. Major methodologies for ranking often exploit principal eigenvectors. Kleinberg’s HITS model is one of such methodologies. The standard approach for computing the HITS rank is the power method. Unlike the PageRank calculations where many acceleration schemes have been proposed, ...

To achieve the highest possible agricultural production, it is necessary to procure appropriate machinery. A tractor most useful machine in agriculture that performs various functions. Therefore, selection of a one key decisions agriculture-production process. This study aims evaluate heavy tractors for production Bosnia and Herzegovina. Since this between different tractors, which are evaluate...
