基于多指标灰区间数关联决策模型的产品方案设计

针对复杂产品方案设计中属性信息的不完全性和不确定性,研究了方案设计中多指标灰区间数关联决策计算方法.提出一种基于灰色系统理论的多指标灰区间数关联决策模型.该模型通过引入灰区间敷序列的范数实现多指标决策矩阵的规范化处理,构建了综合考虑灰色信息的正负理想区间方案,利用方案的优属度从整体性的角度获得最优决策方案.最后,通过大型水轮机的方案设计,验证了该模型的有效性和实用性.

Mechanism scheme design based on multi-attribute gray interval relevant optimized decision-making model

Due to the incomplete and the uncertain interval attribute information in the procedure of the complex mechanism scheme design,a computing method for the multi-attribute decision making of grey interval number is proposed.The proposed model for the multi-attribute decision making of grey interval number is developed based on the grey system theory.By adopting the norm of the grey interval number vector,the multiple-attribute decision making matrix of the grey interval numbers is standardized,and the dummy i...
