摘要
从数学意义和实际应用的角度出发 ,提出了区间数序关系的公理化定义 ;具体给出了区间数的 θ序和L θ序两类序关系 ;讨论了它们所具有的一些良好性质 ;并且从多个角度论述了θ =0 .5
In this paper, an axiomatization definition for the ranking of interval numbers is suggested from the mathematical and practical angle, then two families of ordering relations, θ- order and L-θ- order respectively, are proposed and some rationality properties related to them are investigated. Finally, the essence and rationality of θ- order and L-θ- order with θ = 0.5 are expounded from different aspects.
