针对国际月球科研站（ILRS）项目论证工作的国际化协同需求，结合基于模型的系统工程（MBSE）与并行工程（CE）等工程方法，从数字化协同论证的业务流程出发，为国际性航天工程提供基于模型、架构驱动的数字化协同论证技术体系。本文论述了模型驱动的ILRS协同论证流程，形成了"方法-标准-模型-工具"融合的协同论证技术体系，覆盖使命任务定义与需求分析、概念架构定义与可行性论证、联合方案设计与综合评估等3个阶段、6个过程，从层次、专业、阶段3个维度定义了复杂航天系统的多领域全息模型，定义了面向ILRS多层级、多阶段需求的协同论证标准规范体系，构建ILRS协同论证环境并开展了应用实践，满足ILRS任务的规范性、开放性和并行协同要求，能够为深空探测或其他复杂航天工程的协同论证提供方法指导与技术支撑。
A model-based architecture-driven international space engineering digital collaborative demonstration framework is proposed to meet the international team collaborative demonstration requirement of the International Lunar Research Station (ILRS). Starting from the process of digital collaborative demonstration, this framework considers both Model Based System Engineering (MBSE) and Concurrent Engineering (CE). A collaborative demonstration system integrating "method-standard-model-tool" is defined, and the system modeling and demonstration activities in the stages of mission and task definition and demand analysis, conceptual framework definition and feasibility demonstration, joint scheme design and comprehensive evaluation are discussed as well. From the three dimensions of level, specialty and stage, the ILRS multi-domain holographic model, collaborative demonstration standard, and collaborative demonstration environment are constructed to meet the standardization, openness, and concurrency requirements of ILRS demonstration task, providing method guidance and technical support for deep space exploration or other complex aerospace projects.
