After classifying the impact factors, with grey-system theory, the evaluating grey-groups and their whitening weighing functions are defined;the grey-cluster analysis of each classified impact is performed;based on analyzing results, the calculating method of classified impact index is given. By range of action, the impact classes are grouped to three groups - global impact, regional impact, and local impact;the calculating methods of grouped and overall impact index are presented. Finally, an application example of comparative choice of a category of products - three materials, steel, aluminum and engineering plastics is given.展开更多

In this study the authors used 51 Anatolian Grey bulls, 22 Anatolian Grey heifers and 63 Anatolian Grey x Brown Swiss crossbred bulls. 136 animals in 2-3 years old were used present study. The live weights were found 446.375 ± 20.87 and 508.29 ± 11.88 kg for Anatolian Grey bull and Anatolian Grey x Brown Swiss crossbred bull respectively. Carcass percentage were found 60.57%, 46.84%, 56.87% and the correlation coefficient were calculated between live weight and carcass percentage 0.98, 0.80 and 0.94 for Anatolian Grey bulls, Anatolian Grey heifers and Anatolian Grey x Brown Swiss crossbred bulls, respectively.展开更多
