REVISION: The Impact of Supplier Inventory Service Level on Retailer Demand
Date Posted: May  05, 2015
To set inventory service levels, suppliers must understand how changes in inventory service level affect demand. Although researchers have studied the impact of a supplier's service level on its demand using analytical models and laboratory experiments, this relationship has not, to the best of our knowledge, been tested in the field. We study how the supplier Hugo Boss's inventory service level affects demand from its retail customers. We find increases in historical service level to be associated with statistically significant and managerially substantial increases in current retailer orders (i.e., demand, not just sales). Specifically, upon controlling for other factors that might affect retailer demand, we find a 1 percent increase in this supplier's type 1 service level measured over the prior year to be associated with a 13 percent increase in current retailer demand. Further, we find that retailers that order frequently exhibit a larger reaction to changes in service level, an ...

REVISION: Modeling the Behavior of Patients Who Leave the ED Without Being Seen
Date Posted: Dec  17, 2014
Abandonment in queues has long been recognized as having a significant impact on system performance. Yet, our empirical understanding of the key drivers for abandonment, particularly in observable systems, is limited. Furthermore, most models of abandonment assume that it occurs after a length of time sampled from an exogenous distribution, with no dependence on the system. However, discrete-event simulation, a commonly used tool for decision making in service systems, permits much more complex (and hence accurate) models of abandonment than those simply based on time in system. This paper studies three key drivers of abandonment, namely, waiting time, queue-length, and service rate, which are also tractable for modeling. Using operational data from a hospital emergency department, we show that all three factors affect a patient’s propensity for leaving the waiting area without being seen by a physician (LWBS). Further, these factors interact with each other in a non-linear fashion. ...

REVISION: Execution Quality: An Analysis of Fulfillment Errors in a Retail Distribution Center
Date Posted: Dec  17, 2014
Purchase orders specify many aspects of the fulfillment process, including item quantity, delivery time, carton labeling, bar coding, electronic data interchange, retail ticketing, and others. These fulfillment terms are instrumental for highly optimized supply chains employing automation and techniques such as pack-by-store. When fulfilling a purchase order, a supplier may commit a fulfillment error, i.e., the supplier may fail to adhere to the terms specified by the relevant contract. We present a study of the fulfillment errors that occur in practice using data collected from a major retailer's distribution center. While fulfillment errors involving incorrect product quantities and delivery times have received the most attention in the literature, we find that the majority of fulfillment errors in the context we study involve documentation, bar coding, and retail ticketing. We refer to these as correctable fulfillment errors, since they are amended at the retailer's distribution ...

REVISION: Point-of-Care Testing: Improving Emergency Department Performance through Process Redesign
Date Posted: Dec  08, 2012
Hospital emergency departments (EDs) typically rely on central laboratories to analyze patient samples for the purposes of diagnosing and treating patients. Point-of-care testing (POCT) is a process redesign that shifts the analysis of samples from the central lab to the ED. Using a queueing model, we generate hypotheses about how POCT impacts operational performance and then test those hypotheses empirically using data collected from a large, urban, tertiary, academic hospital. Specifically, we

New: Supply Chain Optimization at Hugo Boss (B) - The M-Ratio
Date Posted: Jun  12, 2009
We evaluate the impact of a supply chain pilot implemented at Hugo Boss. This pilot entailed altering the way in which Hugo Boss orders from its suppliers. We explore the challenge of assessing the impact of supply chain change, the link between operational performance and firm performance, and the relationship between sales, inventory, and product availability.
