The Advanced Vehicle Management System (AVMS) Architecture Studies program defined the candidate vehicle management system (VMS) architectural concepts for advanced air vehicles and defined an integrated tool environment to support development of an advanced VMS (Contract F33615- 89-C-3613).The AVMS program comprised four tasks. Task A determined the functional requirements of the next generation VMS. Task B defined and evaluated a baseline and six candidate architectural concepts. Task C defined a VMS development process based upon DOD Systems Engineering principles. Task D quantified benefits architectures, development processes, and tools, identified shortfalls, and recommended actions to reduce shortfalls.
