ARRVUE: Aircraft RAMP Reallocation and Visualization with Unanticipated Events

ABSTRACT: The ARRVUE solution addresses the identified need for a novel approach to re-planning and re-scheduling when unanticipated work requirements (e.g., corrosion, stress failure, etc.) are identified during initial aircraft inspection at an Air Force Air Logistics Complex. Aircraft RAMP Reallocation and Visualization with Unanticipated Events (ARRVUE) is a genetic algorithm solution to a complex integer programming problem that can generate optimized solutions for Repair Bay allocation. It provides planners with the ability to consider standard maintenance process flows with now modified specific work plans. Repair bay allocation is achieved using actual data from ALC systems under real-world constraints such as physical spots on the RAMP, manpower by skill type, and estimated days in work (DIW) to optimize allocation. The Phase I plan will deliver new functionality for dynamic re-planning that builds upon existing infrastructure for necessary data access, adequate computing, and visualization of the solution and solution test and evaluation for the ALC customer. TDKC will extend the successful Aircraft RAMP Visualization and Simulation System (ARViSS) prototype and complete RAMP simulation as a starting point for the ARRVUE development. The resulting environment provides RAMP planners with a graphical process editor and simulation for re-planning and evaluation of work plan changes. BENEFIT: ARRVUE solves the topic"s dynamic RAMP operations re-planning problem with innovative algorithms and optimization. Commercial applications are more and more reliant upon static planning systems, and are often ignorant of that dependency. From an economic perspective, failure to dynamically re-plan work under way (i.e., power generator scheduled maintenance for critical infrastructure) could be catastrophic. Additionally, we believe that the dynamic re-planning with constraints capability provided by ARRVUE could have numerous applications in other domains.
