Abstract

Authors: Kai Hoberg (Kühne Logistics University), Michael Becker-Peth (Rotterdam School of Management, Erasmus University Rotterdam)

The quality of any operational decision is utterly dependent on the quality of the input data that is available. However, data used for supply chain decision making is often inaccurate. In our study we focus on inventory management decisions that are subject to inaccurate inventory data. Due to shrinkage and loss, the available physical inventory can be lower than recorded system inventory.  To handle this inventory inaccuracy a decision maker can decide to invest into cleaning the inventory data before placing an ordering decision. Alternatively, decision makers can deliberately decide to not clean the data, but to account for the inaccuracy by compensating the actual order decision. Depending on the cost of cleaning and the efficiency loss due to the compensation, decision makers have an incentive to either clean or compensate. We present a set of hypotheses on the cleaning-compensation trade-off and test these hypothesis in a laboratory setting.
