Outbound Movements in a Temperature-Controlled Warehouse

The temperature-controlled supply chain in Portugal is on a par with the most developed cold logistics markets. With a growing and increasingly demanding market dynamics, it is essential that companies in the sector adopt strategies aimed at increasing the efficiency of their operations, promoting an increase in the level of service and a decrease in their operating costs. The need to decrease operational costs should not have any impact on quality, and it is expected that the focus will be on the continuous improvement of internal logistics operations. A study of the outgoing movements of products from a temperature-controlled warehouse of a logistics and transport services company was developed. An integer linear programming model was built and applied, in order to minimize the costs of the logistics operator with the operation of picking and storage. It was possible to obtain savings of about 30.9% compared to the initial scenario.
