Doctoral Dissertations in Logistics and Supply Chain Management: A Review of Scandinavian Contributions from 1990 to 2001

Logistics and supply chain management (SCM) are broad disciplines in which many different, cross‐functional tasks are investigated. In Scandinavia, research in logistics and SCM experienced a significant boom during the 1990s; the steadily increasing interest in participation in the annual NOFOMA Nordic Logistics Conference and the steadily growing number of PhD students enrolled in the Scandinavian research environments emphasizing the study of logistics and SCM bear witness to this intensification. In addition, a great number of doctoral dissertations in this field are completed in Scandinavia, adding greatly to the existent store of knowledge concerning a wide range of logistics and SCM phenomena. However, to date, precious little effort has been devoted to providing an overview of these dissertations. This paper is designed to fill that void. To that end, 75 doctoral dissertations published from 1990 to 2001 are identified. The framework classifies the dissertations into a series of main themes indicative of the state of Nordic research in logistics and SCM. Suggestions for future research based on this survey are likewise provided.

Postponed variety creation: case study in consumer electronics retail

Purpose – Postponement is known as a way to reduce risk and inventories while still providing high product variety and acceptable response times. The paper is a case study that uses simulation for quantifying these benefits for a consumer electronics company.Design/methodology/approach – Improvement potential is first evaluated qualitatively through interviews with dealers of the case company. Next, the benefit of postponement is evaluated quantitatively using discrete‐event simulation with data from operational ERP systems. The conclusions identify conditions under which postponement is beneficial in retail.Findings – In the case company, shop inventory is necessary for high‐volume and low‐variety products. Postponing variety creation to shops has the potential to decrease inventories for these products by 40‐80 per cent. The benefits of postponement depend on delivery speed requirement, product value, product variety and shop size.Research limitations/implications – Many contributions on postponement ha...

Configurations of NPD - Production Interfaces and Interface Integration Mechanisms

This paper describes and illustrates different configurations of the interface between new product development and production processes, including both intra–firm and inter–firm interfaces. These configurations are partly based on a process view of product innovation and partly on a structural view of product innovation. In addition to this typology of interfaces some integration mechanisms are described. The typology will serve as a basis for further research aimed at identifying consistent configurations of the different types of integration mechanisms that are available for industry to increase the effectiveness and efficiency of product innovation processes.

Global Operations Coevolution: Hidden Effects and Responses

Companies are actively seeking competitive advantage through their choice of location and ownership of operations. The purpose of this chapter is to uncover hidden effects of this development and propose how companies can respond to them. The chapter draws on a case study of a Danish industrial equipment firm and describes how its operations configuration has been changing over time. The chapter identifies the key determinants of this change and uncovers some of its hidden effects. The chapter closes with propositions for how to respond to these effects through the development of a distinct systemic approach to control and coordination, which emphasizes not only short-term operational efficiency, but also increasingly long-term strategic effectiveness. The findings advance coevolutionary perspectives on the integration of globally dispersed business systems spanning multiple levels of analysis and involving temporal adaptations. In terms of managerial implications, the study provides managers with lessons for designing a robust system of globally dispersed operations.

Changing Foundations for Global Business Systems

Companies are actively seeking new competitive advantages by changing the location and ownership of their manufacturing processes. This process results in increasing fragmentation and dispersion of global business systems of companies. The purpose of this paper is to identify how companies may improve the integration of such business systems. The paper draws on a case study of a Danish industrial equipment firm. The paper describes and analyzes the company’s operations network configurations, which lay at the foundations of the company’s global business system. It is demonstrated how the operations configurations have been changing over time and affecting the overall business system. The paper identifies the key determinants and outcomes of this change. Moreover, it proposes how the design of operations configurations can be improved through the development of a distinct systemic approach to control and coordination.
