Examining supply chain relationships / Gilbert N. Nyaga in Journal of operations management, Vol. 28 N° 2 (Mars 2010) 

Public ISBD [article]  in Journal of operations management > Vol. 28 N° 2 (Mars 2010) . - pp. 101–114 Titre : Examining supply chain relationships : Do buyer and supplier perspectives on collaborative relationships differ? Type de document : texte imprimé Auteurs : Gilbert N. Nyaga, Auteur ; Judith M. Whipple, Auteur ; Daniel F. Lynch, Auteur Année de publication : 2011 Article en page(s) : pp. 101–114 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Collaborative  relationships  Commitment  Trust  Satisfaction  Supply  chain  alliances  Invariance  testing Résumé : Firms are building collaborative relationships with their supply chain partners in order to achieve efficiencies, flexibility, and sustainable competitive advantage. However, it is unclear if collaborative relationships provide benefits that compensate for the additional expense associated with such relationships. Further, it is unclear what factors promote successful collaborations. This research examines collaborative relationships in two separate studies using structural equation modeling: one study examines buyers’ perceptions and the second study examines suppliers’ perceptions. The two studies are then compared using invariance testing in order to determine economic and relational factors that drive satisfaction and performance from each party's perspective. Results show that collaborative activities, such as information sharing, joint relationship effort, and dedicated investments lead to trust and commitment. Trust and commitment, in turn, lead to improved satisfaction and performance. Results from the two independent studies exhibit similarities and differences; while the conceptual model is highly similar, certain paths vary in their significance and/or their importance across buyer and supplier firms such that buyers focus more on relationship outcomes while suppliers look to safeguard their transaction specific investments through information sharing and joint relationship effort. Managerial and theoretical implications of the findings are discussed.

The differential impact of product complexity, inventory level, and configuration capacity on unit and order fill rate performance / David J. Closs in Journal of operations management, Vol. 28 N° 1 (Janvier 2010) 

Public ISBD [article]  in Journal of operations management > Vol. 28 N° 1 (Janvier 2010) . - pp. 47-57 Titre : The differential impact of product complexity, inventory level, and configuration capacity on unit and order fill rate performance Type de document : texte imprimé Auteurs : David J. Closs, Auteur ; Gilbert N. Nyaga, Auteur ; M. Douglas Voss, Auteur Article en page(s) : pp. 47-57 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Capacity  management  Inventory  management  Operations  strategy  Simulation  Product  complexity Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : This paper examines the simultaneous impact of configuration capacity, inventory level, and complexity on service performance as measured by unit and order fill rates in a configure-to-order environment. Demand skew is treated as a control variable. A simulation model based on data from a leading electronics manufacturer is used to test the hypotheses and identify the impact. Results suggest that there are differential direct and interactive effects of examined variables on unit and order fill rates.
