Abstract

We consider the problem of approximating the branch and size dependent demand of a fashion discounter with many branches by a distributing process being based on the branch delivery restricted to integral multiples of lots from a small set of available lot-types. We propose a formalized model which arises from a practical cooperation with an industry partner. Besides an integer linear programming formulation and a primal heuristic for this problem we also consider a more abstract version which we relate to several other classical optimization problems like the p-median problem, the facility location problem or the matching problem.

Abstract in another language

Wir betrachten das Problem den größen- und filialabhängigen Bedarf eines Modediscounters mit vielen Filialen durch Lotbelieferung zu approximieren. Ausgehend von einer Kooperation mit einem Industriepartner entwickeln wir ein formales Modell für dieses Problem mit Hilfe ganzzahliger linearer Programmierung. Weiterhin beschreiben wir eine Lösungsheuristik und evaluieren ihre Güte anhand von Beispieldaten aus der Praxis.
