Abstract: |
This paper
proposes a new hybrid heuristic (SomAla) for the
capacitated p-median problem (CPMP) which combines a
self-organising map (SOM), integer linear
programming, an alternating location-allocation algorithm (ALA) and a partial
neighbourhood optimisation.
To improve the per-formance of the algorithm, the
structure of the CPMP is exploited for several size-reduction methods and
also for variable-fixing techniques. The capability of this algorithm to find
good solutions in reasonable times for large problem instances has been tested
on several benchmark instances. |
