Huang, Auteur ; Y-H. Chiu, Auteur ; C-T. Ting, Auteur Année de publication : 2012 Article en page(s) : pp. 549–560 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Data envelopment analysis Operational efficiency Marketing Technology gap Hotels Index. décimale : 001.424 Résumé : This study uses the hybrid DEA model, in which the proportionate inputs are evaluated with a radial measure and the non-proportionate inputs are evaluated with a non-radial measure in order to evaluate the impact of marketing expense on the efficiency of Taiwan's international tourist hotels. We further introduce the hybrid DEA into the technology gap measurement to evaluate the technology gaps of marketing expense utilization between different operating types. The empirical results indicate that the inefficiency caused from excess marketing expense is the main reason for lower efficiency in many tourist hotels, especially to chain-operated hotels and hotels that cater to domestic clients. Through the hybrid technology gap measurement, we find that the utilization of marketing resources is more effective for independent, city type hotels, as well as those that cater to international clients.

Inelastic thermal analysis of preloaded steel trusses undergoing heating and cooling stages / T. J. Lin in Journal of engineering mechanics, Vol. 138 N° 5 (Mai 2012)  

Public ISBD [article]  inJournal of engineering mechanics > Vol. 138 N° 5 (Mai 2012) . - pp.468-477 Titre : Inelastic thermal analysis of preloaded steel trusses undergoing heating and cooling stages Type de document : texte imprimé Auteurs : T. J. Lin, Auteur ; C.-W. Huang, Auteur ; Y. B. Yang, Auteur Année de publication : 2012 Article en page(s) : pp.468-477 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Cooling Heating Inelastic thermal analysis Steel truss Updated lagrangian formulation Résumé : The inelastic nonlinear behaviors of preloaded steel trusses undergoing heating and cooling cycles, a problem not well treated previously, are studied in this paper. A bilinear elastoplastic model with a kinematic strain-hardening rule is adopted for steel at varying temperatures. The material softening effects at elevated temperatures are taken into account via the Eurocode 3 reduction factors. The plastic strain resulting from strain reversal upon unloading at a given temperature is considered in updating the stress-strain curve for the next temperature increment. Two simple trusses are adopted to illustrate the physical phenomena involved. All the equations are presented in incremental form, consistent with the updated Lagrangian formulation. The results for the trusses are believed to be new and can be adopted as the benchmarks for validating other numerical approaches used in treating problems involving the heating and cooling stages.
