将武器装备体系分为逻辑体系结构和物理体系结构,给出对体系进行需求分析的过程.探讨了利用UML对武器装备体系进行需求描述的方法和步骤,以海洋监视与打击体系为例,利用UML中的协作图和活动图从顶层分别描述了体系的物理体系结构和逻辑体系结构.建立了利用UML构建的体系静态结构模型到利用着色随机Petri网构建的动态运行模型之间的映射关系.针对实例建立了相应的评估模型,利用可达树分析法初步分析了体系的一些逻辑性能.在构建体系结构模型和评估模型的过程中,各模型间既有延续性,又从不同角度反映了体系结构的不同方面,既可保证需求描述和分析模型的一致性,又可比较全面地分析装备体系结构.
The system of weapon equipment is divided into logical architecture and physical architecture, and the process of requirement analysis of the system is given.Methods and steps of using UML to describe the requirements of weaponry system are discussed. Taking marine surveillance and attack system as an example, Collaboration diagrams and activity diagrams in UML describe the physical architecture and logical architecture of the system from the top respectively, and establish the mapping relationship between the system static structure model constructed by UML and the dynamic operation model constructed by using colored stochastic Petri nets. The corresponding evaluation model is established for the example and some logical properties of the system are initially analyzed by using the reachable tree analysis method.In the process of building the architecture model and the evaluation model, the models are both continuous and reflect from different angles Different aspects of the architecture can not only ensure the consistency of requirements description and analysis model, but also analyze the equipment architecture in a more comprehensive way.
