The main benefit from introducing optimization is that it provides control.
The controller’s role is changed from simply reacting to individual alerts to being in control
of the consequences of different recovery strategies. The optimizer can also be used proactively
to analyze the stability of the current operation, for example to detect flight delays or
cancellations and thereby avoid major problems later that day.
The optimizer evaluates the
possible solution strategies and provides effective means for comparing the different solutions.
To consolidate the operation the optimizer can use commercial information to upgrade and downgrade
flights causing minimum disturbance to passengers.
By solving the entire problem, rather than trying to solve each sub-problem separately,
it is possible to evaluate the full effect of a solution strategy before applying it. Recovery
optimization focuses on specific properties such as the number of changes, the time to recover to
original patterns, cost impacts, passenger disturbances etc. You can combine a number of required
properties to look for the best trade-off between a quick recovery and a low operational cost.
Carmen Fleet Control can use basic crew information like aircraft and crew connections,
on which the crew planning depends. It is also possible to pre-process information to generate re-timing
limits for each flight. The limit describes to what extent each flight can be re-timed without violating
rules, for example duty hour rules. With Carmen Crew Control you can make detailed analyses for individual
crew members.
The most important factor is that Carmen Fleet Control is very fast. Major changes are unlikely
to occur while the optimizer is running. However, if changes do occur which makes parts of the solution invalid, you
have three options: accept part of the solution and repair it manually, accept part of the solution and repair it with
Carmen Fleet Control, or reject the solution in its entirety and start a new optimization job.
