摘　　要：针对概念设计阶段空间任务论证存在协同平台技术不完备、缺少轻量化的设计分析工具、系统之系统层面的仿真验证支持手段不足、协同交互水平和管理的规范化程度受限等问题,提出采用基于模型的系统工程方法,构建空间任务概念设计阶段的协同工作环境。从概念数据模型出发,到逻辑数据模型和物理数据模型,涉及任务需求模型、论证流程模型、多层次化任务数据模型、仿真模型和评估模型等。以模型为核心构建的空间科学任务协同工作环境,提供协同设计支撑平台,集成概念设计、轻量化分析和仿真评估等工具。在该系统上开展论证工作,缩短了论证周期,规范了论证内容,实现全过程的数据管理。In conceptual design phase,the space mission collaborative platform technology is needed to be improved. For lack of quick design and analysis tools,system-of-system simulation tools,synergistic interaction and management standardization,the modelbased systems engineering method is used to establish space mission concurrent design environment in concept design phase.The models include concept data model,logical data model and physical data model.The mission requirements model,demonstration process model,multi-layer mission data model,simulation model and assessment model,etc. are involved. Based on the models,the space science mission concurrent working environment provides collaborative platform that integrated conceptual design,quick analysis as well as system-of-system simulation and assessment tools.The results show the system plays an important role in reducing demonstration duration,standardizing demonstration content and data management in concept design phase.
