材料适用性评价模型构建研究

Construction of Model Evaluating Material Adaptability

在初步建立材料适用性评价指标体系的基础上,组织材料研究与应用方面的资深专家,采用层次分析法对评价指标体系的合理性、评价因子的相对重要性(权重)等开展了评价。通过对专家评价结果的计算分析,确定了指标体系各级评价因子的权重,构建了材料适用性评价模型,确定了材料适用性评价的具体操作方法。通过实证案例分析,该评价模型能够比较客观、真实地概括材料适用性的主要特征,具有可操作性,评价结果与实际情况吻合。

Based on the construction of the evaluation indicator system for material adaptability,experienced experts were invited to evaluate the rationality of the evaluation indicator system and the relative importance（i.e.weight）of the evaluation factors using hierarchy analysis method.By computing and analyzing the experts＇ evaluation results,all levels of the evaluation factors for the evaluation indicator system and the specific evaluation method for the material adaptability were decided.At the same time,the evaluation model for material adaptability was constructed.Several examples are shown that the evaluation model can factually generalize the most characters of the material adaptability and be exercisable.The evaluated results accord with the practical process.
