Original Kurzfassung:
The advancement of industry 4.0 implies fast changing data
and therefore requires flexibility. However, conventional solution methods
for logistics optimization problems very often have to be adapted when
objectives and restrictions are changing. In this paper, a new, generic
solution approach called optimization network (ON) is developed for the
Location Routing Problem (LRP). In an ON, existing solution methods
are applied to the basic problems of the LRP. A meta solver optimizes
the overall result of the network with a black box optimization. An orchestrator is responsible for the introduction of new optimization runs
within the ON, which is possible due to the meta optimization and associated, new variegation strategies for the input data. The developed
approach guarantees that changing external influences only involve an
adaption of affected optimization nodes within the ON and not of the
whole solution approach. Results are compared with an already existing
generic solver and show the potential of the new solution method.
