Abstract

We develop a set of ML models in conjunction with our research partner, a large materials handling equipment manufacturer, and employ the models using our partner's procurement ordering process. This process covers 535,168 orders at suppliers over four years for 36 decision-makers (planners). Using only features that are available at the time a system makes a recommendation, our proposed set of ML models predict (1) whether or not the decision-maker will modify the recommendation and (2) whether such a modification will improve or impair the performance of the system. Our analysis is complicated by the fact that some of the planners have few observations in our training data, leading to poor predictions for those planner-level models. We address this by augmenting our planner-level models with cluster-level models. The latter draws inferences from the predicted behavior of clusters of planners with similar behavior. Using our ML models, we identify a material portion of the order recommendations that can be automated with little, or even a positive, impact on performance. Using our results to automate orders, the firm can (1) free the decision-makers' time for other value-added activities and (2) improve the system's performance.
