摘要
运用分形理论研究决策问题结构，对决策问题进行形式化描述，定义其结构函数和结构指数，并将决策问题从定性上分为良好结构、未结构化和纯不良结构。给出了关于决策问题结构的几个定理，讨论了决策问题结构化的测度，提出了决策问题简化的判据。
This paper utilizes the fractal theory to study the structure of decision problems. A formal description of decision problems is made, and the structure 'function and structure index are defined. Decision problems can be divided into well structured, unstructured and pure ill-structured in quality based upon the above work. Some theorems on the structure of decision problems are given, and a measure of the structured degree for decision problems is discussed. Finally, a criterion for the simplification of decision problems is put forward.
