ABSTRACT

A split order in retail occurs whenever an order is fulfilled in more than one shipment. This entails additional costs to the retailer. In the context of electronic commerce retail, we study the problem of assigning stock-keeping units to distribution centers (DCs) to minimize split orders. Given that the problem is NP-hard, we will discuss several heuristics that leverage actual transaction basket data from a Chinese online retailer, and we will compare them to other benchmark algorithms that do not take into account such data. We will evaluate the results of the test along three dimensions: the average number of shipments per order, workload balance across the DCs, and the number of DCs that are capable of fulfilling a particular order.
