    Project Details


    DESCARTES addresses the problem of disruption management for large
    airlines. This is considered one of the most important and hardest
    problems to deal with in todays planning procedures in the airline
    industry. The goal of the project has been to develop a prototype tool
    enabling the airlines to integrate the management of aircrafts and
    staff when replanning immediately before a flight due to last minute
    The project has progressed in an incremental fashion developing a
    number of individual recovery systems for aircraft, crew, and
    passengers as well as a system enabling these to collaborate when
    generation potential solutions for a disruption. Each of the
    individual systems are useful as a stand-alone system enabling the
    project to give early business benefit to the industrial partner and
    to the software vendor participating.
    A number of different approaches has been tested in the development
    process: heuristics, constraint programming, and traditional
    mathematical programming methods. Also, different approaches to
    solution techniques for the integration of recovery systems has been
    tested: the Integrated Sequential Recovery method consisting of the
    individual subsystems collaboration through a well-defined interface
    to retrieve options, and the Tailored Integration approach, in which
    the generation of potential solutions is influenced by the current
    situation for crew and aircraft concurrently.
    The results of the project now form the basis of a number of
    commercial products marketed by Carmen System AB.
