Supply Chain Complexity – A Bibliometric Analysis

Abstract

Supply chain (SC) structures become more dynamic and complex with an increasing globality. Complexity in SCs relates to three main dimensions. Spatial, horizontal, and vertical complexity are associated with higher uncertainty and missing transparency in Supply Chain Management (SCM). In modern SCM it is always assumed that the SCs are of global nature and reach across borders into different cultures (Vachon and Klassen, 2002, p. 219). This led to a competitive environment where company networks face each other instead of single firms (Kotzab et al., 2015, pp. 525–526). As there are many definitions of Supply Chain Complexity (SCC) that differ to some extent, the definition that underlines the basic approach of this paper is by. In SCM, SCC is defined as a combination of product, process, and network complexity (Bozarth et al., 2009, p. 80). SCC management is a challenging task for SC managers all over the world. If a company is about to fail at SCC management, negative consequences will be generated. These consequences reach from inconsistent incoming material quality to higher transaction costs and a general inflexibility. It is impossible for SC managers to eliminate complexity which establishes an importance to create an understanding of drivers in SCC, determine, evaluate, and implement strategies to reduce complexity. Higher complexity leads to an overall worse performance in SCM, forming an incentive to manage SCC . To review a research field, bibliometric analysis technique is applied. The analysis brings forth the main achievement in answering the following objectives: a) Providing the intellectual foundation of SCC, i.e. the most impactful articles, authors, institutions, and journals as well as the academic output. b) Providing the interdisciplinary character of SCC.
