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, 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.

To determine the matrix of first-order correlation coefficient matrix was C. ,[link widoczny dla zalogowanych], C2, C23, C, were associated vector R. , R2, R23, R. The corresponding values are as follows: 10.20.250166702502] C2. = L01667020.16670166702 【,[link widoczny dla zalogowanych], l0.250.20250.202ll0.40.66670.33330.50.28571C: 2 = l0.33330.50.50.666704110502857050.40.28571033330.33330504] 02857o66670.33330.4JR2l {0. 1845,0.2130,0.1890,0.1919,0.2} R22 {0.3684,0.4338,0.4566,0.5168,0.3581} R,[link widoczny dla zalogowanych], = {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,[link widoczny dla zalogowanych], 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, in order to continue to consolidate and expand the export market,[link widoczny dla zalogowanych], narrowing the gap between developed countries, we must actively study and explore the green packaging science, followed by References [1] Luoya Ming.
