The conceptual framework consists of several rectangular boxes with rounded corners and arrows illustrating a modular simulation system. On the far left, a central box is labeled “Asset module” and contains “Asset specification”. Two boxes point to it: a box above labeled “Requirement schedule module” with a vertical downward arrow and a box below labeled “Acquisition schedule module” containing “Asset acquisition schedule” with a vertical upward arrow. A thick horizontal arrow points from the “Asset module” to a box in the center labeled “Maintenance module” containing “Maintenance schedule”. A second thick horizontal arrow points from this box to a large central box labeled “Maintenance task scheduling, management, monitoring module” which contains “Simulation execution and assessment”. Two modules connect to this central task module: a box above labeled “Resource module” containing “Facilities, equipment, spares” with a vertical downward arrow, a box below labeled “Technician module” containing “Type, role, technician state, competency level, certification state,” with a vertical upward arrow, and a box to the left of the technician box labeled “Workforce planning module” which points to the “Technician module” with a horizontal arrow. Finally, a thick horizontal arrow points from the central task module to a box on the far right labeled “Performance measures module”, which contains “Mean ready-for-issue assets, mean idle technicians, total completed on-time maintenance”.Architecture of the AMMM
