Quantifying the bullwhip effect in supply chains / Richard Metters in Journal of operations management, Vol. 15 N°2 (Mai 1997)  

Public ISBD [article]  inJournal of operations management > Vol. 15 N°2 (Mai 1997) . - pp. 89–100 Titre : Quantifying the bullwhip effect in supply chains Type de document : texte imprimé Auteurs : Richard Metters, Auteur Année de publication : 2007 Article en page(s) : pp. 89–100 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Inventory control Logistics/distribution Résumé : Consider multiple companies operating as a serial supply chain. Within this environment, end users form the demand for the last company in the supply chain, but the demand for upstream companies is formed by the companies in the immediate downstream supply chain link. It has been shown that demand seasonality and forecast error can increase as we proceed up the supply chain. These demand distortions, called the “bullwhip” effect, create inefficiencies for upstream firms. This work seeks to identify the magnitude of the problem by establishing an empirical lower bound on the profitability impact of the bullwhip effect. Results indicate that the importance of the bullwhip effect to a firm differs greatly depending on the specific business environment. Given appropriate conditions, however, eliminating the bullwhip effect can increase product profitability by 10–30%.

A meta-analysis of doctoral dissertations in purchasing / Ajay Das in Journal of operations management, Vol. 15 N°2 (Mai 1997)  

Public ISBD [article]  inJournal of operations management > Vol. 15 N°2 (Mai 1997) . - pp. 101–121 Titre : A meta-analysis of doctoral dissertations in purchasing Type de document : texte imprimé Auteurs : Ajay Das, Auteur ; Robert B. Handfield, Auteur Année de publication : 2007 Article en page(s) : pp. 101–121 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Purchasing Supply chain Meta-analysis Résumé : Purchasing, as a distinct business function, has grown immensely in strategic stature over the past decade. However, the academic development of the field has not paralleled this turn of events. While the academic evolution of any field can be assessed in a variety of ways, doctoral dissertation research provides a useful method of evaluating the intellectual health of a discipline. We analyze doctoral dissertation research in the field of purchasing since 1987, identify key areas of study, examine shifts in topical coverage, evaluate methodological sophistication and the extent of theory development and discuss gaps in research areas. We find that dissertation research in purchasing is still largely exploratory, lacking in dominant paradigms and unifying theories. On a more positive note, our analysis reveals an encouraging trend towards causal and confirmatory research designs and the growing use of organizational, marketing and economic theory to explain purchasing phenomena.

Evaluating and classifying POM journals / Chon-Huat Goh in Journal of operations management, Vol. 15 N°2 (Mai 1997)  

Public ISBD [article]  inJournal of operations management > Vol. 15 N°2 (Mai 1997) . - pp. 123–138 Titre : Evaluating and classifying POM journals Type de document : texte imprimé Auteurs : Chon-Huat Goh, Auteur ; Clyde W. Holsapple, Auteur ; Linda Ellis Johnson, Auteur Année de publication : 2007 Article en page(s) : pp. 123–138 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : POM Management Résumé : A multitude of journals impact the production and operations management (POM) discipline. POM researchers, practitioners, and students all need objective means of rating these journals' impacts on the field. By applying an established multifaceted citation-based methodology, journals are assigned to categories (elite and major) along each of four dimensions (breadth, consistency, trend, and intensity of recognition) and subsequently organized into distinct tiers of importance to the production and operations management field. The data underlying this study consist of 13,992 periodical citations that appeared in three prominent POM journals over a recent five-year period.
