In view of the multi-attribute decision-making problem that the attribute values are grey multi-source heterogeneous data, a decision-making method based on kernel and greyness degree is proposed. The definitions of kernel and greyness degree of an extended grey number in a grey multi-source heterogeneous data sequence are given. On this basis, we construct the kernel vector and greyness degree...

At present, bid evaluation in China mainly adopts the method of traditional comprehensive scoring. And the method of analytic hierarchy process or fuzzy synthetic assessment is also in common use. However, those methods have their own weaknesses, e.g., having a strong subjectivity, lacking in analysis of quantitative indicators, and being unable to reflect the defects of the bidders and reasons...

The present paper proposes neutrosophic soft multi-attribute decision making based on grey relational projection method. Neutrosophic soft sets is a combination of neutrosophic sets and soft sets and it is a new mathematical apparatus to deal with realistic problems in the fields of medical sciences, economics, engineering, etc. The rating of alternatives with respect to choice parameters is re...

Soil samples were collected from the upstream, midstream and downstream areas of Shuimo River in three layers 0–20, 20–40 40–60 cm, each group sample points was located 5 m, 1 km 2 away river bank, respectively. The analysis carried out. Based on investigation research, six indicators, including As, Pb, Zn, Cu, Ni Cr, designated as evaluation factors combination with results collection low or n...

Power transformer is one of the most important equipments in the electric system. Dissolved Gases Analysis is an important method in the diagnosis of internal fault of transformers. Because the signs and types of fault have complicated nonlinear relations, the traditional methods cannot exactly meet the requirements of engineer application. This paper proposes synthesis of relational grey incid...

Recently, grey relational analysis (GRA) has been widely applied in analyzing multivariate time series data (MTS); as a solution to the traditional statistical limitations. GRA, which has been proven to be simple and accurate method for analysing relationship in MTS are broadly used in various disciplines such as economics, sociology and engineering. GRA is employed to search for grey relationa...

The purpose of this paper is to introduce multiattribute decision making based on the concept of interval neutrosophic sets. While the concept of neutrosophic sets is a powerful tool to deal with indeterminate and inconsistent data, the interval neutrosophic set is also a powerful mathematical tool as well as more flexible to deal with incompleteness. The rating of all alternatives is expressed...

The English classroom teaching effect evaluation is looked as the multiattribute group decision-making (MAGDM). Thus, a useful MAGDM algorithm needed to cope with it. Depending on classical GRA process and interval-valued IFSs (IVIFSs), this study builds IVIF-GRA assess effect. First of all, concepts IVIFSs are reviewed. In addition, weights criteria derived through CRITIC method. Afterwards, m...
