摘要
研究了格序决策理论中格序结构不完整的问题。在目前格序决策前期研究成果和以往的规范型决策研究的基础上,基于格提出了赋值函数的概念,并定义了两元素之间的距离,并以此提出格中缺失元素的补充机理和方法。最后以具有格序特征的区间数集作为例子,加以应用。
This paper investigates the problem that the structure of lattice order is not complete in lattice order decision making theory. On the current research development of lattice order decision making and the previous study of formal decision making, the concept of value function is driven and the distance between two elements is defined based on the theory of lattice order decision making. The supplement mechanism and method of default element in lattice is raised. Finally, interval numbers with lattice order characteristic is proposed as an example to illustrate the method's feasibility and rationality.
