基于混合状态Petri网的变结构决策组织设计

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。

Designing the Variable Structure of Decision making Organization Based on the Hybrid Stated Petri Net

Decision making organization is a hybrid stated descrete event dynamic large scale system, the hybrid stated Petri net that is proposed in this paper is a suitable mathematical formalism for modeling the decision making organization. To design a variable structure decision making organization, the paper define a well defined net to construct an initial solution set of problem in terms of the four stages model of decision maker (DM) and interactions among the decision makers, and using characteristic function to describe the variability of links within well defined net. To decrease the dimention of the designing, the structural constraints ( R S) and user defined constraints ( R U) are introduced, and the algorithm is provided for searching the solution set of the feasible variable structure decision making organization satisfying the structural constraints and user defined constraints.
