While traditional research in operations management has focused on mathematical models for improving the flow of physical goods and information, this dissertation takes a quantitative empirical approach. With three distinct research projects it revisits ce ...
This paper examines the financial consequences that inventory leanness has on firm performance. We conduct an econometric analysis using 4324 publicly traded US manufacturing companies for the period 1980-2008. Using an instrumental variable fixed effects ...
In this paper, we introduce the notion of an "opportunity good" as a discount production input that may prove of satisfactory quality upon inspection and otherwise can be returned to the supplier. While in a quality-sensitive setting it is never optimal to ...
We solve a rich routing problem inspired from practice, in which a heterogeneous fixed fleet is used for collecting recyclable waste from large containers over a finite planning horizon. Each container is equipped with a sensor that communicates its level ...
The usage of smartphones has rapidly increased during the last years. In addition to communication capabilities, they are also equipped with several sensors, and are usually carried by people throughout the day. The data collected by the means of modern sm ...
Ce projet consiste en l’élaboration d’un robot utilisant des doigts collants. Ces doigts consistent en un réservoir de colle et de deux résistances faisant office de chauffage. La colle ainsi chauffée fond et passe à travers la base trouée des doigts. Une ...
Globalization, outsourcing and cost optimization have all contributed to increased supply chain vulnerability, yet our understanding of effective mitigation strategies remains limited. In our research, we study the effects of disruptions on supply chain ne ...
Contrary to the long-standing view in the finance literature that firms should maximise payment delays, research in operations management suggests that long payment delays can be suboptimal. In this study, we reconcile these two views by applying a seconda ...
Supply chain management is widely accepted as a means for companies to gain competitive advantage. While product and information flows have been widely covered in the literature, relatively little attention has been paid to the management of a supply chain ...
