ATLAS Corporation is an important producer and distributor in the market of construction materials, developing its operations in Romania. Designing an efficient distribution network for its products was the driver behind the present project. The effort investigates the practices of the company related to the activities of transportation and warehousing, capturing the costs structures for these operations. Based on the operations research theory and making use of binary linear programming, a model that captures the particularities of these activities is proposed. The resulted application constitutes a useful decision support system for the management of ATLAS, allowing for increased interactivity with the input data presented and for implementing different scenarios regarding the design of the distribution network.
