A simulation optimization-based decision support tool for mitigating traffic congestion / S. H. Melouk in Journal of the operational research society (JORS), Vol. 62 N° 11 (Novembre 2011)

In this paper, we develop a robust decision support tool based on simulation optimization to evaluate and recommend congestion mitigation strategies to transportation system decision-makers. A tabu search-based optimizer determines different network design strategies on the road network while a traffic simulator evaluates the goodness of fit. The tool is tested with real-world traffic data.

Team assignments and scheduling for the NCAA basketball tournament / S. H. Melouk in Journal of the operational research society (JORS), Vol. 63 N° 5 (Mai 2012) 

Public ISBD [article]  in Journal of the operational research society (JORS) > Vol. 63 N° 5 (Mai 2012) . - pp. 620–630 Titre : Team assignments and scheduling for the NCAA basketball tournament Type de document : texte imprimé Auteurs : S.

Keskin, Auteur Année de publication : 2012 Article en page(s) : pp. 620–630 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Sports  Integer  programming  Team  assignment  Scheduling  OR  applications Index. décimale : 001.424 Résumé : The National Collegiate Athletic Association (NCAA) organizes a men's basketball tournament every March to determine the national champion for the current season. In organizing the tournament, the emphasis is typically on selection of the most deserving teams to participate and providing a fair, equitable environment in which to play that result in a true, undisputed champion for the season. However, there are growing concerns of dwindling actual attendance at tournament games and increasing financial burden on the NCAA related to reimbursable team travel expenses. In this paper, we describe the development of an integer program designed to optimize team assignments in the sense of minimizing the distance travelled by teams to game sites and the corresponding travel costs. The goal is to increase tournament accessibility to fans as well as lessen the financial impact to the NCAA while maintaining the integrity of the tournament. We test our model against actual tournament assignments from the past 5 years. Results show consistent and significant cost savings and reductions in distance travelled without compromising the fairness and structure of the tournament. Overall, we demonstrate the usefulness of the model in both operational and strategic business decisions.
