As the representative of independence for the indicator, the smaller the correlation of indicators is, the greater the weight is. Hence, the weights of interval numbers of indicators were determined by using correlation coefficient. Relative closeness based on positive and negative ideal methods was calculated by introducing distance between interval numbers, which made decision making more rational and comprehensive. A new method of ranking interval numbers based on normal distribution was proposed for the optimization of mining methods, whose basic properties were discussed. Finally, the feasibility and effectiveness of this method were verified by theories and practice.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
