Grey relational analysis based on fuzzy reliability evaluation of communication networks
3.2 Construction of the results of quasi-optimal sequence of the best sequences from all the best elements in the sequence. . zo (1) a maxx (1) a max (0.8221,1.156,1.2201,1.1293) a 1.2201f. zo (2) a maxx (1) a max (0.8211,1.275,2.041,0.9178) a 2.041i:. zo (15) a maxx (1) a max (0.33,0.67,1,[link widoczny dla zalogowanych],1) a 1i, therefore, may be the best sequence:. z. A (1.2201,2. O41, 1.8357,1.2745,1.1304,1.0078,[link widoczny dla zalogowanych],0.999,1.8742,7.043,1.3987,1.2403,1,1, 1,1) 3.3 find a sequence of difference △ 1 (O.398, 1.1695,0.5149,0.2962,0.1205,0,[link widoczny dla zalogowanych],0.003,0,6.1154,0,0. 3252,0.33,0.67,0.67,0.33) △ 2 a (0.0641,0.766,0.9446,0,0.1381,0.0166,0.0155,0. 8475,4.5518,0.6004,0.1931,0.33,0,0.33,0.67) △ 3 a (0,0,0,0.1376,0.148,0.0115, 0,0.314,0,0.3427,0,0,0.33,0,0.33) △ 4 a (0.0908,1.1232,[link widoczny dla zalogowanych],0.7765,0.0242,0,0. 0157,0.0071,0.4954,5.952,0.5256,[link widoczny dla zalogowanych],0.2435,0.33,0.33,0,0) 3 Liu Qiang, etc.: Based on the fuzzy gray relational analysis of the communication network is reliable assessment. 79.3.6 Comparison of calculated advantage of a correlation of 3.7 15 15 Chi Chi = 0.874 a = O. The results obtained from the above 885: y0. > Y0> y0> y0. Therefore, the indicators given by the sequence and calculation shows that the correlation: the highest reliability of communication network run Ⅲ, Ⅳ second communication network, communication network Ⅱ home three, the lowest reliability of communication network I run. '4 Conclusion Grey has been successfully applied in many fields and achieved very good results. Introduction into the communication network reliability evaluation, the structure can judge clearly realized by the fuzzy concept of qualitative analysis to quantitative analysis.
