This paper introduces a method for Model-based Ontology Coverage Analysis (MOCA) and applies it to SysML models of mission architectures. An ontology is a set of concepts that constitute a common language, standard terminology, and consistent pattern reference across multiple models within an organization, industry, or domain. The purpose of MOCA is to assess the overlap between a system architecture model and a given ontology, and thereby the architecture model's compliance with the ontology and the ontology's utilization by the architecture. We demonstrate MOCA on a SysML model of a humanitarian airlift mission, using a conceptual mission architecting SysML profile model that serves as the ontology. MOCA automates and simplifies reasoning over models, and creates digital model-based artifacts that support stakeholders in concept validation, decision making, and system/mission design. Thus, MOCA enhances digital systems engineering.
