4. Copyright Greg Nordstrom PhD, Apr 2001 Progress to Date Flight schedule driven maintenance scheduling –No longer simulated! Richer, more realistic data sets (XML) –VMA-513 personnel roster Full complement of personnel (202 maintainers) Ranks, quals by workcenter (10 WCs) –Calendar-based maintenance New inspections (7-, 14-, 28-, 56-, 112-, 182-, 364-, 365-, 448-day, 30mo) Mechanic requirements Tool requirements –Tools (tools.xml) Defined schema Code to load/save/manipulate/query Still need accurate counts –Maintenance plan represents typical healthy squadron Architectural, scheduler refinements –Tool-aware constraint generation –Optimization/scaling work (in progress) –Implemented Aircraft Availability Report algorithms

5. Copyright Greg Nordstrom PhD, Apr 2001 MAPLANT Input Data Flight schedule –A/C type –Sortie times (start, end, duration) –Pit/turn info –Event Priorities –Mission types –Ordnance Maintenance plan –Special inspection types –Side numbers –Due dates –Usage-based inspections Repair manual Inspection manual –Job type –Task breakdowns –Task duration –Equipment requirements –Personnel requirements –Task sequencing requirements New for April (simplified MOS) New for April Expanded for April Improved for April (no sim) Bold = In today’s demo

6. Copyright Greg Nordstrom PhD, Apr 2001 MAPLANT Input Data (cont.) Guidance –Shift length –Shift start –Holidays –Pit requirements (“extra” ready aircraft) Maintenance schedule –Shift-level (coarse grain) granularity –“Locked” maintenance actions Technical directives Aircraft inventory –Type –BUNO –Side number –Status & EOC codes –Frame number –Engine number –Lifecounts Roster –Manpower, skill level, qualifications, MOS MAFs Support equipment inventory –Type, location Bold = In today’s demo New for April (structure OK, need real data) New for April (partial)

7. Copyright Greg Nordstrom PhD, Apr 2001 What is being demonstrated Generation of a maintenance look-ahead reflecting: –Flight ops requirements –Aircraft special inspection requirements –1 week’s worth of scheduled inspections –Aircraft type, availability and status (up/down) –6 Night aircraft, 10 Radar aircraft –Maintenance guidance (shift durations, holidays, pit info) Iterative refinement –Phase 1: Shift-level granularity –Phase 2: Tasks scheduled down to the hour (configurable) Integrated MS Project ® -based reporting
