Thesis: M.

This practice, known as SKU segmentation, is widely used by many companies. However, most research and success stories involve a relatively stable portfolio of brands and products, and products with easily identifiable attributes such as profit margins and demand. This thesis attempts to determine if and how a SKU segmentation can be conducted when product mix is constantly changing and many key variables used in traditional segmentations are not known in advance. To explore this problem, we analyze one year of purchase order data and shipment data provided by our sponsor company. The objective is to use data from purchase orders to predict which items are candidates for different supply chain configurations (i.e. an expedited supply chain for time-sensitive products or an efficient supply chain if there is opportunity to reduce cost and still meet demand). We start by mapping the current supply chain process using historical data and interviews with employees. The key piece of the process we want to understand is how early or late products arrive at destination in relation to when those goods are expected in retail stores (a metric we refer to as "destination dwell time"). We then use visualization and statistical analysis to determine what PO information is related to the destination dwell time. After testing various multi-factor regression models to predict the length of this dwell time, we conclude that a neural network regression model predicts this time most accurately. We then assess whether or not it is feasible for the sponsor company to use this model to "speed up" or "slow down" the supply chain for different products as needed. / by Huiping Jin and Brad Gilligan. / M.
