验证、校核和确认(VV&A)过程的规范化对提高建模与仿真全生命周期VV&A工作效率和准确性具有重要意义。从VV&A任务分配和VV&A信息反馈的角度,提出了一种基于可信度指标体系的VV&A过程模型。该过程模型是在DMSO VV&A RPG过程模型基础上,引入可信度指标体系以明确VV&A各阶段的具体任务和反馈机制。另外,引入VV&A“两个方向”和“两类反馈”概念解析了采用该过程模型的VV&A工作思路。最后,将该过程模型用于某飞行器弹道仿真系统的VV&A工作中,实践证明,该过程模型在VV&A工程应用中起到了很好的指导作用。
The standardization of VV & A processes is important to improve the efficiency and accuracy of VV & A’s full modeling and simulation lifecycle. From the perspective of VV & A task assignment and VV & A information feedback, a VV & A process model based on credibility index system is proposed. The process model is based on the DMSO VV & A RPG process model and introduces the credibility index system to clarify the specific tasks and feedback mechanisms in each stage of VV & A. In addition, the concept of VV & A using this process model is analyzed by introducing the concepts of VV & A “two directions ” and “two kinds of feedback ”. Finally, the process model is used in the VV & A work of an aircraft trajectory simulation system. Practice has proved that the process model plays a good guiding role in the application of VV & A engineering.
