摘要
仿真建模是否置信和置信度是否满足要求是仿真建模研究的核心问题。借鉴NASA-STD-7009《建模与仿真标准》,从置信度信息记录、定义与评估的角度,提出了一种仿真建模置信度信息管理方法,设计了仿真系统置信度信息提取工具,提取包括建模置信信息、数据置信信息以及开发过程置信信息三类信息,实现仿真系统置信度信息可记录、可定义、可追溯,达到仿真系统不确定性与置信度信息管理的目的。以一个伺服系统仿真系统置信度评估为例,依据所提置信度管理方法,开发了仿真系统置信度信息管理工具,验证了仿真系统置信度信息管理方法的可行性和有效性。预期可为置信度智能分析提供理论基础与工程思路。
A proposed method for managing credibility information in simulation modeling draws insights from the NASA-STD-7009 standard for modeling and simulation.From the perspective of credibility information recording,definition,and assessment,this method aims to address the core issue of whether the credibility requirements are met in simulation modeling research.A simulation system credibility information extraction tool is designed to extract three types of information including modeling credibility information,data credibility information,and development process credibility information,enabling recording,definition,and traceability of credibility information in simulation models.Taking a servo system credibility evaluation as an example,a simulation system credibility information management tool is developed based on the proposed credibility management method.The feasibility and effectiveness of the simulation system credibility information management method are verified.This work is expected to provide a theoretical basis and engineering ideas for intelligent analysis of credibility.
