pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld.  moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...

As the 750kV substation has the characteristics like incomplete information, uncertain diagnosis result and dual protection configuration, a fault diagnosis method of substation with redundant protection configuration based on rough sets and grey relational analysis is proposed. In this method, the diagnosis decision table which takes advantage of information about wave-recording devices and tw...

This paper presents rough netrosophic multiattribute decision making based on grey relational analysis. While the concept of neutrosophic sets is a powerful logic to deal with indeterminate and inconsistent data, the theory of rough neutrosophic sets is also a powerful mathematical tool to deal with incompleteness. The rating of all alternatives is expressed with the upper and lower approximati...

in the paper an attempt was made to study the performance of indian banks with the help of camel(c-capital adequacy, a- asset quality, m- management quality, e-earnings, l-liquidity i.e. camel) rating system, over the period of five years from (2011 to 2015) and then evaluated out the efficiency of banks with the help of gra (grey relation analysis) technique there by gaining confidence from in...

In order to conduct grey relational analysis of the teaching skills and learning results of aerobics, based on brief introduction of related theories of the grey relational analysis method, this paper uses the viewpoints of system theory to systematically classify the teaching skills of aerobics. Finally, the grey relational analysis method in statistics is combined with the study on the learni...

Quantitative and qualitative fuzzy measures have been proposed to hesitant fuzzy sets 9 (HFSs) from different points. However, few of the existing HFSs fuzzy measures refer to the grey 10 relational analysis (GRA) theory. Actually, the GRA theory is very useful in the fuzzy measure 11 domain, which has been developed for such the intuitionistic fuzzy sets. Therefore, in this paper, 12 we apply ...

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...

Based on detailed analysis of computational principles of the grey relational analysis method and a series of the relevant researches, this paper proposes a web service selection method based on Grey Relational Analysis to improve the shortcomings caused by personal assignment, so as to improve the usability of the algorithm and reduce the limitation of service selection. At the same time, this...
