Wire electric discharge machining (WEDM) is one of the advanced machining processes. Response surface methodology coupled with Grey relation analysis method has been proposed and used to optimise the machining parameters of WEDM. A face centred cubic design is used for conducting experiments on high speed steel (HSS) M2 grade workpiece material. The regression model of significant factors such ...

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...

The capacity (state of charge/SoC) and voltage of lithium-ion batteries are of prime importance in electric vehicles, so their condition-monitoring techniques are extensively studied. This paper focuses on the application of the grey system theory to the parameters analyzing and predicting behavior during the discharge/charge cycles of the battery. Firstly, Grey Relation Analysis (GRA) is appli...

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...

Deng proposed grey clustering analysis (GCA) in 1987. Later, Jin presented a new method in 1993, called grey relational clustering (GRC) method that combined grey relational analysis with clustering. However, the GRC method cannot use a tree diagram to make appropriate classification decisions without re-computation. This study thus attempts to combine GRC and hierarchical clustering analysis. ...

One of the main concepts in grey system theory is how systems should be controlled under incomplete or lack of information situation. Grey number denoting an uncertain value is described in real interval from this concept. In this paper, we introduce the real formal concept analysis based on grey-rough set theory by using grey numbers, instead of binary values. We propose, to extend the notion ...
