In this paper, we propose a novel method for ranking a set of fuzzy numbers. In this method a preference index is proposed based on $alpha$-optimistic values of a fuzzy number. We propose a new ranking method by adopting a level of credit in the ordering procedure. Then, we investigate some desirable properties of the proposed ranking method.

The Otsuka Long-Evans Tokushima Fatty (OLETF) rat, an outbred strain of Long- Evans Tokushima Otsuka rat (LETO) that lacks CCK-1 receptor expression, is hyperphagic and develops obesity and type-2 diabetes. The present study sought to assess how OLETF rats alter intake, preference, and conditioned preference of palatable solutions after acute food deprivation. Our results show that after 24 h c...

This study presents an additive scale model for the Analytic Hierarchy Process (AHP) that suits the decision problem using a linear preference comparison. This study discusses issues related to mathematical denotation, axiom, transitivity and numerical analysis for the additive scale model of AHP. The least squares method and correlation analysis are used to obtain the relative criteria weights...

How can we take account of these products that spring up or are modified – a phenomenon we shall refer to by the generic term “quality factor”? One option is to resort to econometric methods. Such methods have been used at INSEE to calculate selling price indices for microcomputers and printers indices that have been published quarterly since autumn 1991 for microcomputers (going back to 1988) ...

Background: Atrial fibrillation (AF) is heterogeneous at the clinical and molecular levels.

We have space here to give only the briefest outline of the processes we are trying to model; the interested reader should consult one of the standard textS2. The heart consists of four chambers: two atria and two ventricles . Electrically, however, the two atria can be considered as one, and we shall refer only to the atrium ; likewise for the two ventricles. In essence the function of the car...

Background—Low serum magnesium has been linked to increased risk of atrial fibrillation (AF)

Scholarships are the provision of financial assistance for students or with aim that these can continue their education is being achieved. Decision Support System (DSS) a system provide problem communication capability problems in unstructured and semi-structured conditions. The Preference Selection Index (PSI) method was developed by Maniya Bhatt (2010) to solve multiple decision criteria (MCD...

Atrial fibrillation (AF) is an extremely common arrhythmia with important consequences and presently suboptimal therapeutic options.1 A great deal of research has been performed to understand the detailed mechanisms of AF, with the hope that a better appreciation of the fundamental determinants of arrhythmogenesis will lead to the development of novel, more successful treatment possibilities.2
