The table is divided into four horizontal sections, each with a colored left column, a central text column, and a right column containing labeled lists connected by bracket symbols. The top section is labeled “System requirements analysis” in the left column. In the central column, bullet points read: “Integrate the requirements of stakeholders”. “Drafting system requirements”. “System requirements mutual confirmation”. “Establish a traceability relationship”. In the right column, a labeled list reads “System Requirements”. Inside this section, four items are listed vertically: “Function Performance”. “Quality characteristics”. “Physical properties”. “Constraint/Interface”. Each item is preceded by a small square icon labeled “R subscript q”. The second section is labeled “Functional architecture design” in the left column. The central column lists: “Clarify the main functional scenario”. “Main Function”. “Implementation Plan”. “Completing the functional scheme trade-off”. The right column shows “System-level main function”. Inside this section, four items are listed vertically: “Behavior process”. “Flowing item”. “Usage scenario”. “Temporal sequence relationship”. Each item is preceded by a small square icon labeled “F subscript n”. The third section is labeled “Logical architecture design” in the left column. The central column lists: “Function allocation at each level of the system”. “Parameter indicator allocation”. “Port or interface parameters”. The right column shows “Functional logic decomposition”. Inside this section, four items are listed: “Requirements”. “Structure”. “Behavior”. “Main parameter”. Each item is preceded by a small square icon labeled “L subscript g”. The bottom section is labeled “Physical architecture design” in the left column. The central column lists: “Selection of physical components”. “Physical component trade-off analysis”. “Decision on the realization approach”. The right column shows “Physical system architecture”. Inside this section, four items are listed: “Component Model”. “Cost-benefit analysis”. “Characteristic Analysis”. “Use case verification”. Each item is preceded by a small square icon labeled “P subscript d”.The hierarchical process and element decomposition diagram for MBSE system architecture design. Source: Author’s own work
