2. Copyright Chris van Buskirk, Mar 2001 MICANTS Timeline April 2001: –SNAP integration –Practice run May 2001: –PI review & customer demonstration Late Summer 2001: –Initial assessment milestone

3. Copyright Chris van Buskirk, Mar 2001 Recent Progress Architectural refinements Refined Scheduler I/O Requirements GUI Experiments (e.g. MS-Project)

4. Copyright Chris van Buskirk, Mar 2001 MAPLANT Context Diagram Bold = For May demo

5. Copyright Chris van Buskirk, Mar 2001 MAPLANT Input Data Flight schedule (note: hardcoded example data for demo) –A/C types needed for events (i.e. day/night/radar) –Sortie times (start, end, duration) –Event Priorities –Pit/turn info –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 –Personnel requirements –Task sequencing requirements –Equipment requirements Bold = In today’s demo

6. Copyright Chris van Buskirk, Mar 2001 MAPLANT Input Data (cont.) Guidance –Shift length –Shift start –Holidays 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 MAFs Roster –Manpower, skill level, qualifications, MOS Support equipment inventory –Type, location Bold = In today’s demo

7. Copyright Chris van Buskirk, Mar 2001 Scheduler refinements Scaled up to five week look ahead Added shift-related guidance model Added flight ops tempo considerations Types of constraints currently encoded –Mgmt of maintainer resources –Task sequencing (not using today) –Guidance (holidays, shift properties) –Flight schedule requirements

8. Copyright Chris van Buskirk, Mar 2001 What is being demonstrated Automatic generation of five-week look-ahead reflecting: –Aircraft special inspection requirements –17-day inspections –2114-day inspections –428-day inspections –177 total maintenance actions –Aircraft type, availability and status –2 Day aircraft, 8 Night aircraft, 1 Radar aircraft –Flight ops requirements –All night A/C must be available every Wednesday night –Maintenance guidance (shift durations and holidays) Iterative refinement –Phase 1: Shift-level granularity –Phase 2: Tasks scheduled down to the hour (configurable) Integrated MS Project ® -based reporting

9. Copyright Chris van Buskirk, Mar 2001 Demo assumptions, limitations Can fly A/C if not performing a maintenance task –Need the actual specs here Simulation of flight schedule effects –Can turn on/off demanding night missions tempo one day per week –Working w/ ISI on FltSched content refinements –Working w/ ISI to review alternative FS-related report for suitability Only 7-, 14- and 28-day inspections considered –No sequencing constraints on task execution have been defined yet Manpower availability –Simplified modeling of tasks’ skill requirements –Accurate distribution of MOS codes and special quals across workcenters not modeled
