Operational hedging against adverse circumstances / Dan Weiss in Journal of operations management, Vol. 27 N° 5 (Octobre 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 5 (Octobre 2009) . - pp. 362–373 Titre : Operational hedging against adverse circumstances Type de document : texte imprimé Auteurs : Dan Weiss, Auteur ; Michael W. Maher, Auteur Année de publication : 2010 Article en page(s) : pp. 362–373 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Operations  policy  Operations  strategy  Hedging  Airlines  Stochastic-dominance  Uncertainty  Empirical  research Résumé : This paper investigates operational hedging against severe disruptions to normal operations. It offers a new method to evaluate the extent that operations policy serves as a hedge against adverse circumstances. We apply the proposed method to explore how supply chain characteristics affect the responses of airlines to the acute demand fall off after the September 11 terrorist attacks. Results indicate that operational hedging vehicles (fleet standardization, high-fleet utilization, an aircraft ownership policy rather than leasing, and international operations) are more powerful in protecting firms than using financial instruments. The study contributes in guiding managers as to how operations policy can serve as an imperative factor in mitigating exposures to low-end performance levels.
