摘要

对仿真模型和模拟器应用进行验证、确认和可信度评估的有效方法,是航空工业在系统设计、验证和培训中日益依赖建模和仿真的推动因素。作为传统的以文档为中心的方法的补充,本文提出了一种模拟器应用的可信度评估方法,该方法在仿真过程中直接向最终用户提供可信度信息。其核心思想是,模拟器中的每个模型都用描述可信度不同方面的元模型进行扩展。元模型包括许多静态可信度度量和一个在仿真期间可能变化的动态度量。该概念在萨博鹰狮战斗机的两个系统模拟器中实现和测试。根据评估,该概念有助于直观地概述模型依赖关系,以及单个模型和模拟的可信度信息。

A Concept for Credibility Assessment of Aircraft System Simulators
An efficient methodology for verification, validation, and credibility assessment of simulation models and simulator applications is an enabler for the aeronautical industry’s increasing reliance on modeling and simulation in system design and verification and on training. As a complement to traditional document-centric approaches, this paper presents a method for credibility assessment of simulator applications, in which credibility information is presented to end users directly during simulation. The central idea is that each model in a simulator is extended with a metamodel describing different aspects of credibility. The metamodel includes a number of static credibility measures and a dynamic measure that may vary during simulation. The concept is implemented and tested in two system simulators for the Saab Gripen fighter aircraft. According to the evaluation, the concept facilitates an intuitive overview of model dependencies, as well as credibility information for individual models and for a simulat...
