Note—Removing a Self-Imposed Restriction in Modelling Hierarchical Decision Processes
指出文献中多层层级系统的决策模型仅限于严格金字塔结构，并证明这种限制是自我施加的，现有模型可修改以表示多种非金字塔结构。
Models of decision-making in multi-level, hierarchical systems in the literature have been restricted to structures where the system is strictly pyramidal in nature. We will show that this restriction has been self-imposed and that existing models can be modified to represent a wide range of nonpyramidal structures.
