"Can we control the impact of the weather on sales?" (2016)Acrobat pdf document
by Xavier Brusset

AbstractThe weather has a large influence on what we buy, when, and where. With climate change, this influence means that sales of consumer products vary wildly, even within seasons.

"Développement d'une plateforme de services logistiques par Internet" (2009)Acrobat pdf document

Abstract Rapport final présenté à la Région Wallonne dans le cadre des travaux menés pour le projet TransLogisTIC. Ce rapport présente les résultats d'une étude micro-économique sur les impacts pour les PME dans le transport de marchandises des outils de collaboration et de partage de l'information développés par les partenaires du projet TransLogisTIC.

"Managing risk in transport: an overview" (2009)Acrobat pdf document
by Xavier Brusset

Abstract This presentation was given in the course on transport risk management in the Mastère Spécialisé en Management de la Supply Chain at HEC, Jouy en Josas, France.

"Transportation procurement support using Data Envelopment Analysis" (2008)This is a pdf document to be opened with Acrobat Reader
by Xavier Brusset, Per Agrell and Peter Bogetoft

Abstract This paper presents a method1 for a shipper to screen and choose carriers in a Request For Proposals (RFP) and set up enduring relationships with them. The screening is done using a frontier analysis model (inscribed within Data Envelopment Analysis or DEA). The method is compared to a traditional method of selecting carriers through a Mixed Integer Linear Program (MILP).

"Transport contract optimization under information asymmetry: an example" (2006)pdf document to be opened with Acrobat Reader

Abstract Transport cost is second in importance after production cost in industry. It is the purpose of the present paper to solve the single period, single echelon, shipper-carrier transport model established in an earlier paper when demand addressed to the shipper and the spot transport price, two exogenous stochastic variables, follow a bivariate exponential probability distribution function. We evaluate the objective functions of the carrier and shipper over one period reiterated with a mix of long-term and short-term procurement strategies under four scenarios of information sharing. We provide optimal parameters for the shipper’s procurement policy where transport capacity needed by the shipper and spot price of transport follow exponential probability distribution functions. We study the behaviour of the different variables versus each other.

"Choosing a transport contract over multiple periods " working paper by Xavier Brusset (2009).

Abstract We study a series ofmulti period gameswhere a shipper and a carrier have the choice between three types of contract to frame their relationship (Quantity Flexibility Clause, Minimum Purchase Commitment and Price-Only Relational Contract). A spot market also enables the shipper to buy extra transport capacity if necessary. Both demand and price on the spot market are dependent exogenous stochastic processes.e outcome of this endogenous choice of contract entails is presented here as the result of a bargaining game taking place at regular intervals. e conclusions are applicable to practical management for any type of price and demand distributionwhen the carrier’s investment in capacity is sunk and there exist a market for marginal capacity from all carriers in the transport sector.

An empirical study of contracts on rent sharing in transport. working paper by Xavier Brusset.

Abstract Transport service providers are part and parcel of a supply chain. As such, they also have to calibrate their capacity to the necessities of the members of the supply chain they serve. Transport cost is the second in importance after the production cost in industry. It is the purpose of the present paper to study the impact of information sharing and contractual instruments between a supply chain and its transport suppliers. After reviewing the literature, we propose a model to measure the benefits in terms of transport cost, standard deviation of transport cost and effective order fill rate. We evaluate three scenarios for a two-shipper single-carrier two-echelon model with a mix of long-term and short-term procurement strategies: perfect information, asymmetric information and private information at one level of the supply chain.

Quantitative analysis for Internet-enabled Supply chains by Pinar Keskinocak and Sridhar Tayur in Interfaces, volume 31, issue 2, pages 70-89

Abstract A supply chain, from an operations perspective, has three components: sourcing or procurement, manufacturing and distribution, and inventory disposal. In each component, the Internet is significantly affecting how supply chains are being managed, leading to new challenges while ultimately promising to provide value. The likely future is collaborative supplychain management that promises to make, for the first time, the dream of virtual integration a reality. Quantitative modeling provides companies decision support as well as insights for better management of supply chains. But there are still a number of challenges that require further OR/MS analysis.

How information influences the cost of transport in a supply chain, a monte carlo simulation. by Xavier Brusset

Abstract. The present paper studies the impact of information sharing and contractual instruments on a shipper and her transport suppliers through a monte carlo simulation. After reviewing the literature, we propose a model to measure the benefits in terms of expected transport cost and variance of this cost. We evaluate three scenarios over a reiterated-single period setting in a shipper carrier single-echelon model with a mix of long-term and short-term procurement strategies: perfect information, asymmetric information and private information at one level of the supply chain. After spelling out the optimal parameters for the procurement policy, we evaluate the rent transfer between carrier and shipper in a numeric example using the monte-carlo method.
