摘　　要：许多学者和决策实践者认为,决策柔性应当具有价值.但这一直觉推测并未在一般的决策理论框架下得到的证实.文章的目的就是要从理论上证明这一推测.通过回顾关于柔性的文献,归纳出柔性的本质属性(范围和速度).进而在决策理论的一般框架下,给出了决策柔性的数学定义,建立了柔性决策模型,并指出了该模型与经典柔性决策模型之间的关系.最后,应用该模型,证明了"决策选项的价值随着决策(范围和(或)反应)柔性水平的提高而增加"这一基本结论.Many theorists and decision-makers believe that decision-making flexibility should have some value. But this conjecture is not proved in a general framework of decision-making theory. This paper is to prove the conjecture. Through a review of literatures on flexibility, this paper draws out the essential properties of flexibility, i.e. range and speed. Further, this paper generally provides the formal definition of decision-mak- ing flexibility, builds a model of flexible decision-making, and points out the relationship between our model and the classical models of flexible decision-making. Finally, with our model, we prove that the value of a decision alternative increases as its （range and/or response） flexibility increases.
