面向体系化设计与运用的虚拟开放场景构建

Virtual open scenario construction for system of systems oriented design and application

场景作为飞行器设计方与使用方之间的重要桥梁,其复杂度随着飞行器的体系化发展趋势不断提高,使得双方需要更直观、更易理解、更高效的场景描述和构建方式,为设计与运用的相关应用提供“共同语境”。在典型的场景应用需求分析的基础上,提出了虚拟开放场景(VOS)的定义和主要特征,进而提出了场景要素的多维映射体(MDM)等概念及VOS构建流程。针对流程中的主要环节,提出了对MDM进行裁剪的双层评估矩阵、从MDM实例到组件的开放式封装等方法,并且探讨了一种支持VOS组合及交互的支持系统架构,以灵活构建可体现不同关注侧重的虚拟开放场景族。最后给出了一个面向多机海上搜救体系的虚拟开放场景族构建案例,实现了从全局视角和局部视角描述搜救直升机所在场景,验证了所提概念与方法的有效性。

Scenario as an important bridge between the aircraft designers and uses, its complexity rises ceaselessly with the systematic development of aircraft trend. Designers and users need more intuitive, more understandable, and more efficient methods in scenario description and construction, so as to have a unified "common context" for the design and application of related applications. Based on the analysis of typical scenario application, the definition and main characteristics of Virtual Open Scenario(VOS) oriented to system of systems oriented design and application are proposed, the Multi-Dimensional Mapping(MDM) of scenario elements and construction process of VOS are proposed. In view of the main links in the process, a two-layer evaluation matrix for tailoring MDM and open encapsulation from MDM instances to components are proposed, and a support system architecture that supports VOS composition and interaction is discussed to flexibly build a virtual open scenario family that can reflect different concerns. Finally, a virtual open scenario family construction case for multi-aircraft maritime search and rescue system is presented, which realizes the description of search and rescue helicopter scenario from global and local perspectives and verifies the effectiveness of the proposed concept and method.
