We present the Concordant-Ranks (CR) strategy that decision makers use to quickly find an alternative that is proximate to an ideal alternative in a multi-attribute decision space. CR implies that decision makers prefer alternatives that exhibit concordant ranks between attribute values and attribute weights. We show that, in situations where the alternatives are equal in multi-attribute utilit...

A surface topography characterization parameter system based on fractal parameters has been established, and several estimation methods for these have suggested accordingly. Since scale dependence exists in conventional methods, it is necessary to find an method with uniqueness. An ideal multi-scale measurement of polished proposed this study. Polished surfaces two materials, WC-Ni 9Cr18Mo, are...

Supply chain risk evaluation is a multi-criteria decision making problem under fuzzy environments. To tackle the problem, this paper firstly identifies and discusses some of the important and critical decision criteria and constructs the evaluation indicator framework. Then this paper presents a modified grey relational analysis method based on the concepts of ideal and anti-ideal points. In th...

Brain ideal midline estimation is vital in medical image processing, especially in analyzing the severity of a brain injury in clinical environments. We propose an automated computer-aided ideal midline estimation system with a two-step process. First, a CT Slice Selection Algorithm (SSA) can automatically select an appropriate subset of slices from a large number of raw CT images using the sku...

BACKGROUND The concept of cardiovascular health (CVH) was introduced as a global measure of one's burden of cardiovsacular risk factors. Previous studies established the relationship between neighborhood characteristics and individual cardiovascular risk factors. However, the relationship between neighborhood environment and overall CVH remains unknown. METHODS AND RESULTS We analyzed data fr...

Multi-criteria decision-making methods (MCDM) represent a very powerful tool for making decisions in different areas. Making rational and reliable decision, while respecting factors, is challenging difficult task; MCDM models have great impact on achieving this goal. In paper, new technique presented—ranking alternatives by defining relations between the ideal anti-ideal alternative (RADERIA), ...

let $s$ be an ordered semigroup. a fuzzy subset of $s$ is anarbitrary mapping   from $s$ into $[0,1]$, where $[0,1]$ is theusual interval of real numbers. in this paper,  the concept of fuzzygeneralized bi-ideals of an ordered semigroup $s$ is introduced.regular ordered semigroups are characterized by means of fuzzy leftideals, fuzzy right ideals and fuzzy (generalized) bi-ideals.finally, two m...
