随着相变材料在材料科学领域的不断发展,其评价和选择逐渐受到人们的关注,相变材料评价指标通常包括相变焓、比热、导热率、密度、过冷度和价格等各方面,但是其性能评价不够科学和系统.本文利用VIKOR法构建了法不同层次的指标体系,建立了相变材料性能评价模型,以AHP法确定指标体系的权重,通过评价模型对各种相变材料的综合性能进行排序,研究表明,基于VIKOR法的评价模型的评价结果与实际研究相吻合,说明VIKOR法具有较强的实际性和理论性.
The choice of phase change materials need to consider phase change enthalpy, specific heat, thermal conductivity, density, degree of super-cooling and price and so comprehensively.In order to solve the problems of the conflict and different dimensional attribute, the index system of different levels and phase change material performance evaluation model are established based on VIKOR method.Determine the weight of the index system by the AHP method and sort all kinds of phase change materials based on the evaluation model for the comprehensive performance.Research showed that the evaluation model based on VIKOR method was in conformity with the actual research to indicate that the VIKOR method had strong theoretical and practical.
