| 摘 要： | 在分析煤炭企业可持续发展评价方法的基础上，建立了煤炭企业可持续发展评价指标体系，构建了基于误差反向传播算法（BP算法）的多层前向神经网络模型．为减小希望输出与实际输出之间的误差，从输出层神经元到输入层神经元逐层反向修正各连接权，并在网络训练学习的过程中不断执行误差反向传播修正，以提高网络对输入模式响应的正确率．通过算例验证了运用BP神经网络评价煤炭企业可持续发展的有效性和准确性． |

| Abstract: | Based on analyzing the existing methods for evaluation of sustainable development of coal enterprises, an evaluation index system was established. A neural network model with multi hierarchic structure was built based on error back propagation (BP) algorithm. The conjunction weights of the neural network are modified layer by layer from output layer to input layer in the process of neural network training to reduce the errors between the anticipated and actual outputs. A case study was conducted and it verified the validity and accuracy of the proposed method. |
| Keywords: | coal enterprises sustainable development BP neural network evaluation |
