Grey Relational Analysis And Its Application On Multivariate Time Series
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...
متن کاملResearch and Application for Grey Relational Analysis in Multigranularity Based on Normality Grey Number
Grey theory is an essential uncertain knowledge acquisition method for small sample, poor information. The classic grey theory does not adequately take into account the distribution of data set and lacks the effective methods to analyze and mine big sample in multigranularity. In view of the universality of the normal distribution, the normality grey number is proposed. Then, the corresponding ...
متن کاملDissimilar friction stir lap welding of Al-Mg to CuZn34: Application of grey relational analysis for optimizing process parameters
This study focused on the optimization of Al—Mg to CuZn34 friction stir lap welding (FSLW) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using Grey relational analysis (GRA). First, the degree of freedom was calculated for the system. Then, the experiments based on the target values and number of considered levels, corresponding orth...
متن کاملOptimizing turning operation of St37 steel using grey relational analysis
Nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. Since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. To reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...
متن کاملGrey Relational Analysis and Its Application Based on the Angle Perspective in Time Series
The research scope of grey relational analysis has not been developed in recent years, and the exiting GRA models are all based on three perspectives, including distance perspective, slope perspective, and area perspective. Under this situation, a novel model called grey relational analysis based on angle perspective (GRAAP) was developed in this paper for the first time, and this model can exp...
