摘要: 武器装备体系需求建模过程充满了不确定性,而体系需求建模的质量直接影响到需求模型的有效性和可靠性,最终影响待建武器装备体系的构建效果。在重点分析武器装备体系需求建模利益相关者和需求建模内容中存在的不确定性因素的基础上,提出了一种基于贝叶斯网络(BN)的武器装备需求建模质量评价方法。该方法在充分利用专家知识和统计数据的基础上,利用BN的状态描述与推理机制,可以有效描述、处理体系需求建模过程中出现的不确定性问题;并且利用BN的诊断推理可以找出影响建模质量的关键因素组合。最后通过仿真实例对方法进行了验证。

Abstract: The requirement modeling process of weapon system-of-systems is full of uncertainty.On the other hand,the quality of weapon system-of-systems requirement modeling effects validity and reliability of requirement models directly,and further,the weapon system-of-systems constructing.This paper develops a quality evaluation method of weapon system-of-systems requirement modeling based on Bayesian Network(BN) for clearly understanding of its essence and ensuring consistency and reliability in modeling process.This method well uses expert knowledge and statistic data,and deals with the uncertainty problems in weapon system-of-systems requirement modeling.Making use of reasoning method in BN,it also can get the key influencing element combination.A simulation example shows that the method has good expansibility and feasibility.

Key words: Bayesian Network(BN), weapon system-of-systems, requirement modeling, quality evaluation
