To accommodate future demands for large-scale complex system design and functional analysis,the concept of model-based systems engineering(MBSE)was introduced in missile design,and an MBSE-based conceptual design process for surface-to-air missiles was proposed.Firstly,stakeholder requirements for surface-to-air missiles were clarified,and missile mission scenarios were defined.Functional analysis was then conducted based on design requirements,utilizing missile mission scenarios for functional decomposition,and completing the transformation from requirements to functions.Based on the system functions of the missile,the missile's architecture composition was mapped,and the logical and physical architecture design of the surface-to-air missile system was carried out.Finally,the conceptual design scheme for the missile was formulated,and verification and optimization were performed for the missile scheme,thereby preliminarily achieving the conceptual design process for surface-to-air missiles.
