Application of Combined Weighted Method Based on Weight Confidence on Selection of Engineering Materials
摘 要
针对综合评价选材中评价指标的权重难以合理确定这一问题,在分析现有组合赋权法的原理与不足的基础上,提出了基于权重置信度的组合赋权法;以低温存储罐材料的选择为例,运用此组合赋权法对分别由层次分析法、修正熵权法和BP神经网络法得到的8个评价指标的主观权重、客观权重和智能权重进行组合,并以所得组合权重,采用改进的理想解法对10种候选材料进行综合评价。结果表明:此法得到全硬态301型不锈钢是最佳的低温存储罐材料,与实际应用一致;说明采用基于权重置信度的组合赋权法来确定工程材料评价指标的权重是合理可行的。
Abstract
Referring to the question that it is hard to determine the index weight of comprehensive evaluation for the selection of engineering materials, combined weighted method based on weight confidence is put forward on the base of analyzing the theory and shortcoming of existing combined weighted method. Taking the choice of storage pot material under low temperature working condition as an example, subjective, objective and intelligent weights of eight kinds of evaluation indices, obtained by analytic hierarchy process, improved entropy method and back propagation network respectively, were combined with combined weighted method proposed above. Ten kinds of candidate materials were evaluated according to improved technique for order preference by similarity to ideal solution (ITOPSIS) with the combined weights obtained. The results show that the 301 stainless steel is the best storage pot material under low temperature working condition, this accords with industry practice. All above show that the weights of evaluation indices for engineering materials determined by the combined weighted method are reasonable and feasible.
