Carmen Crew Recovery Solver helps you recover
from disruptions on the day of operation. The solver can be connected
to existing day of operation systems.
The Carmen Crew Recovery Solver automatically produces
recovery options for major and minor disruptions. An option can contain
any combination of flight swaps, activated stand-by duties and controlled
legality relaxation. The objective is to recover as quickly as possible
with as little change as possible and thus retain maximum service levels
for passengers.
The solver will rapidly produce an initial feasible solution. After this
the solver will continue investigating more solution strategies that can
lead to lower costs, less crew to contact or a better passenger service
level (e.g. more cabin crew with specific language qualifications).
The user can easily investigate different trade-offs, e.g. between a quick
recovery and a low operational cost, or between minimum changes and a
stable operation. It is also possible to set exact goals, e.g. an upper
limit for the number of stand-bys to use in solutions, maximal rule deviations,
etc. The result is presented with customized Key Performance Indicators
for easy comparison and selection.
All legality and quality is controlled with Carmen's modelling language
Rave. Rave guarantees for all our clients that the solutions produced
always respect the company's legality and quality policies, as well as
the targets for costs and passenger service levels. Rave also makes it
possible to identify exactly what rules and quality constraints are available
to relax in critical situations (e.g. long-term legality to temporary
push problem ahead, or a minor violation of check-out time to negotiate
a special solution with a crew member).
Changes can be introduced at short notice by the local
system administrator. This will ensure that the system delivers the best
possible solutions, even after changes to crew agreements, timetables,
company policies, planning processes, etc.
By integrating a lot of solvers the potential is even greater. The Crew
Recovery Solver can rapidly guarantee that the proposed solutions are
feasible and effective for the entire operation, when coupled with the
Fleet Recovery Solver and Passenger Recovery Solver.
Carmen Crew Recovery Solver is a stand-alone system
designed to work in an integrated operations control environment. The
solver reads input and delivers solutions as XML messages to and from
an asynchronous queue.
