A target-based MADM method covers beneficial and non-beneficial attributes besides target values for some attributes. Such techniques are considered as the comprehensive forms of MADM approaches. Target-based MADM methods can also be used in traditional decision-making problems in which beneficial and non-beneficial attributes only exist. In many practical selection problems, some attributes ha...

In this paper, we define a two-parameter generalization of bihyperbolic Jacobsthal numbers. We give Binet formula, the generating functions and some identities for these

Project selection is considered as an important problem in project management. It is multi-criteria in nature and is based on various quantitative and qualitative factors. The main purpose of this paper is to present a new rank-based method for project selection in outranking relation. According to this approach, decision alternatives were clustered in the concordance matrix and the discordance...

In this paper, we present an original unsupervised segmentation scheme which splits a grey level image into different sets of connected pixels whose grey levels are homogeneous. This approach is based on an analysis of a triangular table denoted ”Normalized connectivity degrees pyramid”. This method is used in order to detect cytomegalovirus retinitis lesions by fundus image analysis. First, we...

Polynomials are common algebraic structures, which often used to approximate functions, such as probability distributions. This paper proposes directly define polynomial distributions in order describe stochastic properties of systems rather than assume polynomials for only approximating known or empirically estimated Polynomial offer great modeling flexibility and mathematical tractability. Ho...

The extended TOPSIS method is proposed to solve multi-attribute group decision-making problems which the attribute values take the form of interval grey linguistic variables and attribute weight is unknown. To begin with, the relative concepts of interval grey linguistic variables are defined; the operation rules, the properties, and the distance between the two interval grey linguistic variabl...
