Auto rostering testing

  1. Set dates
    Try to set period for full month not touching other months. If you select 28DEC-31JAN legality module might not be able to work out valid roster because of DEC part (ie not enough day offs in DEC)
  2. Data source
    To run rostering in small batches for testing purposes use only small subset of crew. Ie only captains.
  3. Assign

  • Use appropriate fairness bases with scoring system
  • Day off fill in is mandatory for legality purposes
  • Dynamic grouping optimizer - use this only for empty rosters or rosters with very few activities assigned prior to rostering run
  • Don't forget to fill times for morning/evening flights when using morning/evening fairness in scoring system
  • Roster patterns are used only for grouping flights
  • Ignore some legality rules if crew is dirty
  • Score
    • Level 1/2/3 fairness corresponds to fairness bases in General tab. Don't use BLH fairness for ref acts, keep attention to that.
    • Grouping primary acts - grouping flights using roster pattern from General tab - give this a high value, all rosters are better when using grouping
    • Activity count fairness - use if you want fairness basing strictly on assign count
    • Morning/evening flights fairness uses morning/evening flights definitions from General tab
    • Vacation friendly acts - tries not to put evening flight before day offs or vacations and not to put morning flights after day offs or vacations - very soft rule. Will work only for rosters with plenty enough crew for this fairness to kick in.
    • Destination fairness also checks for destinations inside pairing. Tries to equalize different destinations for crew. All destinations are valued the same.
    • Days off distribution works with soft rules tab. Soft rule trying to keep days off between duties/assignments in constraints given. Will work only for rosters with plenty enough crew for this fairness to kick in.

General tips

  • Don't run rostering for single crew expecting good results. Scoring system is a comparative system thus you need more than 1 crew. Preferably more or less a number of crew required for coverage.
  • Experiment with different grouping values in roster pattern. Sometimes 4 flights in a row is good, sometimes 3 etc. When you have different flights with very different flights length you will get better results when doing rostering separately for longhauls and short flights.
  • Scoring system doesn't guarantee full coverage with every value. 100% fairness might not give you full coverage. 60% grouping 40% fairness might. Even more: 60% grouping and 40% fairness might give you better fairness than 100% fairness. Experiment and remember grouping is extremely important. Fairness modules don't do grouping. And grouping is good.
