TEACHING THE PRODUCTION/OPERATIONS MANAGEMENT CORE COURSE: INTEGRATING LOGISTICS PLANNING ACTIVITIES

This paper discusses the benefits of restructuring the introductory undergraduate production and operations management (pom) course to improve its pedagogical effectiveness and to better convey the importance of integrating logistics planning activities. The introduction of a dynamic integrative semester-long case study which involves students in applying pom concepts and tools through a simulation game is reported.     

THE IMPACT OF PRODUCT RECOVERY ON LOGISTICS NETWORK DESIGN

Efficient implementation of closed‐loop supply chains requires setting up appropriate logistics structures for the arising flows of used and recovered products. In this paper we consider logistics network design in a reverse logistics context. We present a generic facility location model and discuss differences with traditional logistics settings. Moreover, we use our model to analyze the impact of product return flows on logistics networks. We show that the influence of product recovery is very much context dependent. While product recovery may efficiently be integrated in existing logistics structures in many cases, other examples require a more comprehensive approach redesigning a company's logistics network in an integral way.     

GREENING THE SERVICE PROFIT CHAIN: THE IMPACT OF ENVIRONMENTAL MANAGEMENT PRACTICES

This paper explores the relationship between environmental practices and performance in services and the impact of such practices on the external portion of the service profit chain. Using structural equation modeling, it tests the hypotheses developed with data from the European hospitality industry. The findings suggest that environmental practices are positively related to performance through the mediating effect of enhanced customer satisfaction and loyalty. The paper's contributions include: the conceptual development of the relationship between environmental practices and performance in services, the incorporation of environmental practices within the service profit chain, and the testing of their impact on customer satisfaction.     

COLLABORATION AND EVALUATION IN THE SUPPLY CHAIN: THE IMPACT ON PLANT‐LEVEL ENVIRONMENTAL INVESTMENT

Manufacturing organizations can potentially improve environmental management both by increasing the level of investment in environmental technologies and by shifting that investment away from pollution control and toward pollution prevention. However, managers must not only consider their own manufacturing operations in isolation, but also those of others along the supply chain. This paper explores two dimensions of supply chain activities—collaboration and evaluation—that might be leveraged by plant managers to improve environmental management in their own plant. The linkages with suppliers and customers were assessed. Both customer‐ and plant‐initiated collaboration were found to have a significant effect on the level and form of investment in environmental technologies for a sample of Canadian plants. Of greatest importance, as customer‐initiated collaborative activities increased, plant‐level investment in environmental management was increasingly allocated toward pollution prevention. In contrast, only very limited evidence was found that evaluative activities influenced environmental investment.     

PLANNING AND SCHEDULING THE REPAIR SHOPS OF THE DEUTSCHE LUFTHANSA AG: A HIERARCHICAL APPROACH

To plan and schedule the repair shops for recoverable parts at Deutsche Lufthansa AC, we designed a hierarchical model consisting of two levels. The top level calculates the optimal number of parts in the system to guarantee a certain service level while minimizing the capital tied up in parts. Given this provision, the lower level schedules the repair of parts so that the service level is actually maintained. Using queuing theory, the solution gives special attention to the different hierarchical dependencies. Lufthansa has implemented the model for its repair shops of electronic parts. Their experience with the model is discussed briefly.
