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.
