基于改进三次差异驱动的区间数动态多属性决策方法

Dynamic Interval Number Multi-Attribute Decision Making Method Based on Improved Three Stage Difference Driving

对于属性权重未知属性值为区间数的动态多属性决策问题,提出基于改进三次差异驱动的多属性决策方法.此方法吸收三次差异驱动的优秀思想,并对其进行改进,进而将其扩展至区间数领域,在综合考虑不同属性的重要程度不同时刻备选对象的差异的基础上,引入了“能量”消耗指数,从整体角度分析备选对象发展变化中的不同波动情况,获得科学的排序结果,为决策者提供决策参考.最后通过算例分析及与其他方法比较分析,进一步验证了方法的科学性与可行性.

For the dynamic multi-attribute decision making problem with unknown attribute weight and interval number attribute value,a multi-attribute decision making method based on improved three stage difference driving is proposed.It is improved by absorbing and improving the excellent idea of three stage difference driving,and extended to the field of interval number;on the basis of comprehensively considering the importance of different attributes and the differences of candidate objects at different times,the"energy"consumption index is introduced to analyze the different fluctuations in the development and change of candidate objects from an overall perspective,so as to obtain scientific ranking results and provide decision-making reference for decision-makers.Finally,through the example analysis and comparative analysis with other methods,the scientificity and feasibility of the method are further verified.
