决策组织是一个混合状态的离散事件动态大系统，它适合于用该文提出的混合状态Ｐｅｔｒｉ网来建模。为了设计一个变结构决策组织，该文基于决策员的四阶段模型和决策员之间的交互关系，定义了一个称之为良定义网的初始集，并利用示性函数来描述良定义网中各连接的可变性。为了降低设计维数，引入结构约束和用户约束，并给出了求满足结构约束和用户约束的可行变结构决策组织解集的算法 The decision-making organization is a mixed state discrete event dynamic system, which is suitable for modeling with the mixed state Petri nets proposed in this paper. In order to design a variable structure decision-making organization, this paper defines an initial set called good-defined network based on the interaction between decision-makers’ four-stage model and decision-maker. The variability of each connection. In order to reduce the design dimension, the structure constraint and the user constraint are introduced, and the algorithm to solve the feasible variable structure decision solution set which satisfies the structure constraint and the user constraint is given
