A proposed approach for verifying a Modular Open Systems Approach (MOSA)-enabled system architecture in Systems Modeling Language (SysML) based system models of military ground vehicle domains. Using this approach, Model Based Systems Engineering (MBSE) practitioners can verify that a given MOSA-enabled architecture in the system model is compliant to pre-defined MOSA-adopted reference architecture models. The approach utilizes military ground vehicle domain-specific operational scenarios and their associated domain context-specific architecture verification rules, architecture verification metrics and compliance-scope. MBSE professionals can implement the proposed approach using automated or semi-automated solutions.
