工程材料评价指标体系的构建方法

摘要

In order to construct scientific and reasonable evaluation index system for engineering materials and realize selecting material by comprehensive evaluation,on the base of that determining evaluation index system of engineering materials belongs to tree structure,constructing evaluation index system of engineering materials with question list method,target decomposition method or the combination of both methods was proposed.Regarding the construction of evaluation index system for storage pot material under low temperature working condition as example,the application of methods mentioned above on the construction of evaluation index system of engineering materials was introduced.The results show that question list method, target decomposition method and the combination of both methods are suitable for the construction of evaluation index system of engineering materials.%为构建科学合理的工程材料评价指标体系，实现综合评价选材，在确定工程材料评价指标体系属于树型结构的基础上，提出了采用问题罗列法、目标分解法或者两者相结合的方法构建工程材料的评价指标体系，并以低温存储罐选材时评价指标体系的构建为例，介绍了上述方法在工程材料评价指标体系构建中的具体应用。结果表明：问题罗列法、目标分解法或者两者相结合的方式适用于工程材料评价指标体系的构建。
