UNIS LLC is a third-party logistics provider that helps companies manage their supply chain, including warehouses, through technology and information services. A particular challenge is organizing inventory within warehouses, a process known as slotting. The goal of this project is to develop a warehouse slotting algorithm to minimize the time for workers to access products, increase worker safety, and save on operation costs, while following appropriate business rules (e.g. grouping similar items, storing heavy items in prescribed areas).
