材料选择的集对分析方法及应用

SPA analytic method and its application on material selection

基于集对论的原理,建立了零件材料选择的集对综合评价模型,主要考虑在零件设计时,如何在多种可用材料中合理地选出最佳的一种。该数学模型使材料选择的定性评价定量化、精细化、明朗化,提高了评价工作的可操作性和科学合理性。

Based on the principle of SPA theory, the SPA comprehensive evaluation model for materials selection of parts established, it mainly takes into consideration on how to select reasonably an optimal kind among multi-adoptable materials while designing component parts. This mathematical model could let the qualitative evaluation of the material selection be quantified, fineness and clear-cut, thus raised the operability and scientific rationality of the evaluation work.
