Development Trend of MBSE and Investigation of Concurrent Collaborative Demonstration for Chinese Lunar Exploration Program

Chinese lunar exploration program is facing a new development situation, which raises higher demands for many aspects of the Chinese lunar exploration mission, including demonstration of plans, overall design, system development and orbital detection. Currently, Model-Based System Engineering (MBSE), concurrent engineering and other new methods and new techniques have received growing attention, both domestically and internationally. In this paper, the research status of MBSE from the aspects of processes, methods, tools and applications, are summarized to analyze the development trends of it. Integrating the project characteristic and mission demands of the Chinese lunar exploration program, the model-based demonstration framework for concurrent and collaborative design is proposed, and then the analysis is conducted on two categories of key technology of the framework. Based on a dependency graph, the consistency maintenance technology across disciplines, levels and regions is proposed. And, the component service packaging integration technology based on OSLC is proposed. The initial application has been conducted on the demonstration and design for International Lunar Research Station, in which multi-roles cooperation is realized, the full synchronization time is less than 1 minute. The designing practice of ILRS provides the instructional framework and practical exploration to comprehensively promote MBSE for further lunar exploration program.
