Ajouter le résultat dans votre panierThe operating impact of parts commonality / Asoo J. Vakharia in Journal of operations management, Vol. 14 N°1 (Mars 1996)
Titre : The operating impact of parts commonality Type de document : texte imprimé Auteurs : Asoo J. Vakharia, Auteur ; David A. Parmenter, Auteur ; Susan M. Sanchez, Auteur Année de publication : 2007 Article en page(s) : pp. 3–18 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Between- and within-product parts commonality MRP system Résumé : This paper investigates the impact of between- and within-product parts commonality on the workload of a manufacturing firm using an MRP system. More specifically, we investigate the impact of several operational factors and their interactions with part commonality. We develop and validate a large simulation of an MRP system and integrate the generation of planned order releases with workload estimation on the shop floor. The results indicate that increasing parts commonality has positive effects in terms of average shop load but does lead to greater variability in terms of loadings as well as increasing system disruption. Further, we also find that the number of work centers significantly impacts the shop floor effects of commonality. Hence, although an increase in parts commonality results in less design effort and increased standardization, the negative effects of increasing commonality often appear on the shop floor level. This points to a need for the effective management of parts commonality by assessing the tradeoff between strategic “benefits” and operational “costs”.

Titre : Machine dedication and process flexibility in a group technology environment Type de document : texte imprimé Auteurs : John B. Jensen, Auteur ; Manoj K. Malhotra, Auteur ; Patrick R. Philipoom, Auteur Année de publication : 2007 Article en page(s) : pp. 19–39 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Group technology Job-shops Routing flexibility Simulation Résumé : This study investigates changes in inventory and customer service performance of a job-shop that desires to adopt a Group Technology (GT) philosophy in its shop floor operations. Simulation methodology is pursued to explore tradeoffs in shop performance between the routing flexibility of non-dedicated machines in a functional job-shop and the setup efficiency of dedicated machines in shops that have machine cell layouts. Further, traditional and GT-based scheduling procedures are investigated in these different shops to determine the conditions under which a GT philosophy may be profitably employed only in layout decisions, only in scheduling decisions, or in both layout and scheduling decisions. Results from this study show that shop layout choice is not a simple decision that can capitalize either on the high routing flexibility of the functional job-shop or on the setup efficiency advantages of a cell shop. The tradeoffs between routing flexibility and setup efficiency must be made carefully. The impact of demand variability on performance is also dependent on the type of layout. In general, product volume variability more adversely affects the performance of functional job-shops, while product mix variability has greater impact on the performance of cell shops. Finally, sensitivity analysis is performed to show that maintaining balance between the utilization of machines is a major determinant of performance, and consequently the best layout.

Titre : POM research productivity in U.S. business schools Type de document : texte imprimé Auteurs : Scott T. Young, Auteur ; Brad C. Baird, Auteur ; Madeleine E. Pullman, Auteur Année de publication : 2007 Article en page(s) : pp. 41–53 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Productivity Service operations Work measurement Résumé : This study examines the publication output of individuals and business schools in the field of Production and Operations Management (POM). A ranking system was devised based upon publications in the leading POM journals. Two ranking approaches were applied to business schools: productivity and quality. Articles were counted in two ways: one ranking counted each article as one unit, and authors “shared” the unit equally, and the second ranking gave each contributor credit for one “distributed” unit.
These are the first publication productivity rankings for the field of POM, and are based upon publications in the years 1989–1993.DEWEY : 658.57 ISSN : 0272-6963 En ligne : http://www.sciencedirect.com/science/article/pii/0272696395000380

Titre : Institutional research productivity in production and operations management Type de document : texte imprimé Auteurs : Manoj K. Malhotra, Auteur ; Hemant V. Kher, Auteur Année de publication : 2007 Article en page(s) : pp. 55–77 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Production and operations management Research productivity Institutions Résumé : This study investigates the research contributions of academic and other institutions in the area of Productions and Operations Management (POM) over the past 15 years. Similar studies have also been previously conducted in other functional areas of business such as Finance, Marketing, MIS and Management. Institutional productivity is assessed by counting the number of articles and number of standardized pages published in five major POM research journals during a 15 year period from 1980 to 1994. The journals selected include Management Science, Decision Sciences, Journal of Operations Management, IIE Transactions and International Journal of Production Research. A previous study had ranked these as the top 5 journals publishing high quality POM research. Results indicate that among the 50 institutions that emerged from our study as the top ranked ones, no single institution dominated the rankings across all the journals. The diversity of institutions reflected in these rankings shows that the field of POM is maturing and growing. Even though the overall research productivity has increased tremendously over the course of the past 15 years, the longitudinal analysis reveals that often there are periods of high and low productivity in the life of individual research institutions. The results of this study can be used by industrial researchers, doctoral students, and faculty members to assess the primary sources of contribution to each journal, to better guide their publication strategies, and even to help plan their careers.
