In this paper we describe a decision support system that was developed for supporting strategical and tactical decision making with respect to location of warehouses and the allocation of customers to warehouses. The system is currently used by the Department of "physical distributions" within Heineken breweries to help management with mid- and longterm logistic decisions. The core of the system is a large mixed integer linear programming model. This paper containes a (long) abstract of the research carried out. A complete description of the results will be submitted for publication elsewhere
