    Project Details

    Description

    CIAMM started its activity in late 1999. The goal has
    been to develop planning tools based on mathematical modelling,
    which can be used in everyday planning and replanning in larger
    companies. The planning problems are usually so complex, that a
    human planner cannot take into account all possible solutions.
    During the three project years the main case study has been the
    steel plate storage at Odense Steel Shipyard. The storage constists
    of 250 stacks containing more that 3000 types of steel plates. The
    plates are lifted by two gantry cranes sharing tracks and hence
    unable to pass each other. When a specific plates is needed in the
    production, all plates obove this in the stack has to be moved to
    get access to the plate. Hence each plate is lifted unproductively
    a number tiems before it is actually removed from the storage. The
    problem addressed is how to organize the storage in order to
    minimize the number of superfluous lifts. The project has developed
    methods both for planning the daily sequences of lifts and for and
    on-line dispatch strategy for operating the cranes. Saving of 50 -
    60 % on the current practice has been achieved.
    In addition, a packing system has been developed based on a
    real-life case from Bang & Olufsen, in which boxed are packed into
    containers taking into account also constrants regarding loads on
    the items and support of these.
    Finally, a methodology for IT-system development with a large
    optimization content has been developed and described - the
    technique resembles the DSDM method, and much attention is given to
    rapid prototype developments and to knowledge exchange between end
    users and developers, since this ahs turned out to be a major
    obstacle in the development process.
