Improving sourcing decisions in NPD projects / Marc Wouters in Journal of operations management, Vol. 27 N° 1 (Janvier 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 1 (Janvier 2009) . - pp. 64–77 Titre : Improving sourcing decisions in NPD projects : Monetary quantification of points of difference Type de document : texte imprimé Auteurs : Marc Wouters, Auteur ; James C. Anderson, Auteur ; James A. Narus, Auteur Année de publication : 2009 Article en page(s) : pp. 64–77 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Product  development  Sourcing  decisions  Purchasing  Structural  equation  modeling Résumé : During new product development (NPD), firms make critical design and sourcing decisions that determine the new product's cost, performance, competitive position, and profitability. The purchase price of materials and components for the new product provides only part of the picture for design and sourcing decisions. All-encompassing analyses of cost and performance, such as total cost of ownership, are extraordinarily difficult to implement because they are demanding in terms of time, data and cooperation. We study monetary quantification of points of difference, which enables an NPD team to base its decisions instead on more focused, strategically-pertinent analyses of costs and performance. We propose a substantive model of its antecedents and consequences. We then test this model with data from matched samples of 144 project leaders and 144 cost analysts who participated in the same NPD projects. Using structural equation modeling, we also test hypothesized differences in perspectives between project leaders and cost analysts. Results demonstrate the pivotal role of monetary quantification of points of difference among the sourcing alternatives being considered, especially for cost analysts. Results also demonstrate that Decision Justification to senior management drives the NPD team's decision-making process. Finally, monetary quantification of points of difference leads to Uncertainty Reduction, which is found to be the primary antecedent of the judged success of applying analysis of cost and performance.

Pounding of an 18-story building during recorded earthquakes / Fabian R. Rojas in Journal of structural engineering, Vol. 138 N° 12 (Décembre 2012) 

Public ISBD [article]  in Journal of structural engineering > Vol. 138 N° 12 (Décembre 2012) . - pp. 1530–1544 Titre : Pounding of an 18-story building during recorded earthquakes Type de document : texte imprimé Auteurs : Fabian R. Rojas, Auteur ; James C. Anderson, Auteur Année de publication : 2013 Article en page(s) : pp. 1530–1544 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Pounding  Seismic  separation  Steel  structures Résumé : During the San Fernando Earthquake (1971), two of the three triaxial recording instruments placed in an 18-story steel building in Los Angeles recorded the impact with an adjacent reinforced concrete parking structure. This provided an excellent opportunity to evaluate the modeling of such an event using current computer programs (time step, structure damping, impact damping, and use of a gap element) to evaluate the effect of the impact on the strength demands and evaluate the design implications (necessary separation). Although only the base recorder worked during the Northridge Earthquake, it was possible to evaluate the computer modeling using the San Fernando data, and then use the model to evaluate the building behavior under the stronger Northridge Earthquake (1994). Results of the numerical model indicate an agreement with the extensive cracking identified by the results of a damage investigation following the Northridge Earthquake in the two moment resistant transverse frames of the steel building. Much of this damage in the lower 10 floors of the transverse frames was probably because of the impact with the adjacent parking structure at the fifth floor level. Damage in the upper portion is thought to be because of the increase response in the higher modes of vibration caused by the impact and horizontal setback of the building at the fifth level.
