模糊Petri网在装备保障指挥决策中的应用研究

Research on Application of Fuzzy Petri-Net for Equipment Support Command Decision

针对装备保障指挥决策的非结构化特点,结合模糊Petri网的基本理论,建立了一类装备保障指挥决策的模糊Petri网模型(ZYFPN)。给出了模型中模糊推理过程的形式化推理算法,算法考虑了推理过程中的众多约束条件,包括命题在规则中的权重、变迁触发的闲值、规则的可信度以及多结论规则等。以装备保障配置地域转移决策为例,描述了从决策问题分析到ZYFPN模型建立,以及基于矩阵运算的决策推理过程的相关问题。应用这一模型,可以提高基于规则的装备保障指挥辅助决策系统的设计、分析和维护效率。

According to the non-structure characteristic of equipment support command, a fuzzy Petri net model is built in this paper, which is called ZYFPN. The model combines the basic theory of fuzzy Petri nets. And then, an algorithm of formalized fuzzy reasoning process is proposed, in which all of the constraints in the reasoning rules, such as weights of the input propositions, thresholds of the transitions, degree of the rules, and multiple conclusions rules, are considered. The proposed method is illustrated by the application to the decision of the equipment support deploying field transfer. This paper describes some problems from the analysis of decision case and the ZYFPN model＇s building to the reasoning process based on matrix operation. Using this approach, the equipment support command decision support system is easy to be designed, analyzed and maintained.
