An Approach for System of Systems Executable Architecture Structure Analysis

为全面揭示集成体系的结构性质,提出了一种基于DoDAF视角模型构建的集成体系可执行体系结构的结构分析框架.通过分析面向状态和面向行为的建模工具,比较研究了Petri网、自动机与事件结构图建模和分析的优劣势;基于集成体系可执行体系结构活动发生概率和延时的随机性,详细阐述了这3种建模工具相应的随机扩展表示方法;鉴于Petri网能全面展示集成体系结构性质的特点,及自动机和事件结构图细化系统行为建模优势,综合形成了集成体系的结构分析框架并给出详细的建模分析步骤.该方法为研究评价和度量集成体系能力提供了理论基础.

In order to obtain the structure properties of system of systems, an structure analysis framework of system of systems executable architecture based on view models of DoDAF is presented. Firstly, advantages and disadvantages of Petri nets, automata and event structure graphs are compared by analyzing tools of state-oriented approaches and incident-oriented approaches. Then respective extensions of the referred three approaches are proposed owing to the occurred probabilities and delays of the activities of system of systems executable architecture. In the end, a new framework for system of systems executable architecture structure analysis is brought forward combining the advantage of obtaining the structure properties from executable architecture models for Petri nets and easily modeling behaviors for automata and event structure graphs. Theory basis is provided for capability evaluation by the proposed approach.
