The grey system theory, which has been extensively used in many areas, is appropriate for forecasting. It is necessary to put forward new models or algorithms to improve its performance, especially for forecast accuracy. In the forecast process of grey model, the size of data sample and the number of variables can affect forecast accuracy. In this paper, we first put forward a new method to cho...

-This paper proposes a grey interval relation TOPSIS method for the decision making in which all of the attribute weights and attribute values are given by the interval grey numbers. In this paper, all of the subjective and objective weights are obtained by interval grey number and decision-making is based on four methods such as the relative approach degree of grey TOPSIS, the relative approac...

Any digital image can be represented mathematically in matrix form. The number of lines in the matrix is the number of lines of the digital image (also called image height), whereas the number of columns in the matrix is the number of columns in the digital image (also called image width). In the following we will consider the simplest case, i.e., the case of grey scale image processing; in tha...

Abstract In this study, aiming at the multi-attribute decision-making problem with incomplete and uncertain attribute weight information value of interval numbers, a grey target model numbers based on positive negative clouts is proposed. Firstly, in model, linear transformation operator number used to normalize original decision information, are designed. Secondly, after space projection dista...

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, an optimization model is proposed to simulate and predict the current situation of smog. The takes interval grey number sequence with known possibility function as original data, constructs a time-delay nonlinear multivariable $\text{MGM}(1,m \vert \tau,\gamma)$ based on new kerne...
