Abstract: This master thesis discusses the problem of storage management in the second largest warehouse of a Quebec company working in the agricultural industry. Warehousing faces a seasonality of demand concentrated during 3 to 4 months of each year. This concentration of demand causes losses in the efficiency of warehouse storage operations, which become overloaded. In addition, the products are stored in different packages and are quantified in different units, which makes the warehouse management problem more complex. In order to analyze the situation and solve the problem, we start by determining the capacity of this warehouse. Then, we analyze the inventory needs and we finally propose and solve a problem of Storage Location Assignment Problem (SLAP). We start with a presentation of our industrial partner and a detailed presentation of the problem. We then present a literature review of the articles dealing with the studied problem. Next, a detailed and comprehensive analysis of the theoretical capacity of the warehouse under study is performed. This step is followed by the inventory needs analysis where the process of the pallet storage needs assessment is presented. Next, a mathematical model is proposed to solve the Storage Location Assignment Problem (SLAP); this model minimizes the loss of pallet space in the warehouse racks, the number of hidden pallets on the floor and the number of unassigned pallets. We study the performance of the model under changing product demand concentration, warehouse configuration, pallet types and product types. We end with a conclusion and future directions for this problem.
