可执行体系结构的HCPN建模方法

Approach to executable architecture modeling from DoDAF to HCPN

美国国防部体系结构框架(DoDAF)作为一种通用的系统体系结构描述规范,得到业界的广泛认可。但由于其本身描述形式的局限,无法支持对集成系统体系结构动态特性的分析。在建立DoDAF产品描述与层次化着色Petri网(HCPN)不同建模语言间对应关系的基础上,提出了以集成体系结构操作活动模型(OV-5)、操作规则模型(OV-6a)、逻辑数据模型(OV-7)为主体的可执行模型五阶段建模方法。旨在使由DoDAF体系结构产品建立HCPN可执行模型的过程规范化、步骤化,为实现体系结构可执行模型的自动转换提供技术支持。

As a common integrated system architecture specification the department of defense architecture framework（DoDAF） has already gained the widespread acceptance in the world.However,the limitations of its descriptive form render it unable to support the analysis for the dynamic behaves of complex integrated systems.Therefore,an executable model is needed to fulfill the requirement of analysis and evaluation.Aiming at standardizing the process of the executable modeling and providing technical support for the automatic conversion between the descriptive products and executable models,a 5-stage modeling approach is developed to support the derivation of a hierarchical colored Petri net（HCPN） model that can reveal the logical and behavioral characteristics of the architecture form DoDAF operational products.Focusing on the activity model（OV-5）,operational rules model（OV-6a） and logical data model（OV-7）,the corresponding relation of the modeling language between DoDAF products and HCPN is explored,which is served as the basis of the modeling approach.An example of air defense（AD） system is given to illustrate the modeling process.
