二层系统模型是描述具有层次特性管理决策系统的有效方法, 本文讨论了一类有广泛代表性的二层线性规划模型及其几何特性, 给出了这类二层线性规划模型最优解的几种最优性条件。

Two-level system models can efficiently describe the manage-mental decision system with multilevel.In this paper,a class of two-level linear programming models, which have extensive representativeness, is dis-cussed.Geometric characteristics of the two-level linear programming mod-els are studied.Optimality conditions of the two-level linear programming models are given.
