WebDec 9, 2024 · Grey correlation method is a new analysis method in grey system theory. It measures the correlation degree between factors based on the degree of similarity or difference between factors. The calculation steps of this method are displayed as follows [ 23 ]: Step 1: Determining the reference sequence and the comparison sequence. Grey relational analysis (GRA) was developed by Deng Julong of Huazhong University of Science and Technology. It is one of the most widely used models of grey system theory. GRA uses a specific concept of information. It defines situations with no information as black, and those with perfect information as … See more Let where the Grey … See more • Chan WK and Tong TKL, (2007), Multi-criteria material selections and end-of-life product strategy: Grey relational analysis approach, Materials & Design, Volume 28, Issue 5, Pages 1539-1546 See more GRA is an important part of grey system theory, pioneered by Deng Julong in 1982.

WebOct 1, 2024 · The establishment of such an evaluation system starts with building a grey correlation optimization model via developing an improved resolution coefficient grey correlation (IRCGC) method. The method was used to comprehensively evaluate various AM technologies. WebThe grey system theory was developed by Deng , which is a very typical system analysis method. The idea of the grey correlation system method is to calculate the correlation coefficient between each criterion and the best performance, and then compare the degree of correlation between standard objects and all evaluation object [16,17,18 ... http://ijbssnet.com/journals/Vol_7_No_2_February_2016/10.pdf arti 78 dalam bahasa gaul
