摘　　要：综合灰色系统理论、理想解法和欧氏距离,提出了一种新的基于理想关联距离度的课程评估方法,给出了建立评估模型的基本步骤.定量处理的指标,经过理想化、标准化后,定义关联数,由此计算关联距离度.通过灰色关联距离度,建立了一种接近最优方案远离最差方案的评估模型.并通过学院近期的课程评估实例分析,验证了该方法的准确性和可行性.A multi-objective decision-making model was built by ideal grey relational distance. Course evaluation model was constructed based on the grey relation theory, ideal solution and Euclidean distance. Quantized indicators were by way of idealized, standardized processing. And correlation coefficient is defined. This method established a new grey relational distance similarity degree. The new similarity degree reflects the relatedness and the different shape among a selected scheme, the ideal solution and negative ideal solution. And then, take a specific case for example in this method. Evaluation results show its practicability and effectiveness.
