Product packaging based on gray relation evaluation of green
Weight vector (see [4]), resulting in a corresponding weight vector W2l, W22, W23, W24: W,. = {0.2605,0.6334,0.1061} W = {0.2605,0.6334,0.1061} W23 {0.4284,0.2605,0.3111} W2 {0.75,0 .25} 5.2.2 determining the weights of second-level evaluation for environmental indicators, resource indicators, economic indicators and social indicators for the evaluation of this packaging is green,[link widoczny dla zalogowanych], the importance of the order of E,> E> E> ; E, according to the weight of the idea of seeking, to determine a comparison matrix T. And the weight vector W. . 5.3 Evaluation of gray correlation coefficient of the green at all levels to determine the first order correlation coefficient of 5.3.1 to determine 3l, -. . . . . .

To determine the matrix of first-order correlation coefficient matrix was C. , C2, C23, C, were associated vector R. , R2, R23, R. The corresponding values are as follows: 10.20.250166702502] C2. = L01667020.16670166702 【, l0.250.20250.202ll0.40.66670.33330.50.28571C: 2 = l0.33330.50.50.666704110502857050.40.28571033330.33330504] 02857o66670.33330.4JR2l {0. 1845,[link widoczny dla zalogowanych],0.2130,0.1890,0.1919,0.2} R22 {0.3684,0.4338,0.4566,0.5168,0.3581} R, = {0.2736,0. 321l, 0.3552,0.321 l, 0.321l} R, = {0.3142,0.3214,0.4167,0.4583,0.4} 5.3.2 second-order correlation coefficient, which determine the procedures and principles associated with a coefficient of order entirely similar to the R = W. × [R. , R2, R3, R] obtained, R = {0.32630.45620.40770.45090.454l}. It can be seen that the maximum correlation coefficient of 2 companies, so that in these five companies, enterprises 2 is the product during packaging, the preferred business. 6. Conclusion In today's increasingly fierce international competition, in the era of burgeoning environmental movement, in the 2008 Olympics approaching,[link widoczny dla zalogowanych], in order to continue to consolidate and expand the export market, narrowing the gap between developed countries, we must actively study and explore the green packaging science, followed by References [1] Luoya Ming.
