“…The difference in connectivity levels between the two networks was explained by their different structures. In line with evidence from the literature that analysed the global maritime network (Hu and Zhu, 2009;Ducruet et al, 2010;Kaluza et al, 2010;Ducruet and Notteboom, 2012), the MSN presented a 'hub-and-spoke' structure and tested positive for a scale-free network with a power-law distribution of network links, meaning that a reduced number of countries had a large number of connections and that connectivity opportunities were unequally distributed among nodes (Figures 3 and 4) (Gonzalez-Laxe et al, 2012). In contrast, the ITN was a small-world network, where nodes were tightly connected in a 'point-to-point' network configuration.…”

“…With regard to maritime freight transport, the economic and financial crisis has affected both the global containerized throughput and the large ports' connectivity [46]. The economic downturn in Europe during the period 2008-2009 led to declining container throughput, further fueling concessions between the port industry and policy-makers in terms of substantial cargo shifts.…”

Logistics Services Sector and Economic Recession in Greece: Challenges and Opportunities

2018

View full text Add to dashboard Cite

Abstract:The recent economic recession in Greece has had a detrimental impact on all national business activities, with the logistics industry being one of the most affected sectors primarily due to the significant decrease in market demand for goods and services. In this regard, the aim of this research is to identify key challenges and prospects for the Greek logistics services industry stemming from the recent economic crisis era through a critical literature taxonomy, a semantic analysis of the reviewed articles, and a questionnaire-based survey involving 140 executives from the third-party logistics sector. In principal, the recent economic crisis is reported to have significantly affected logistics service providers, thus further imposing structural reforms in the industry. The reduction in operating profits of transport companies is noticeable with the onset of the economic crisis, specifically in 2016. Nevertheless, logistics executives are optimistic regarding the near future, provided that educated and informed strategic management decisions are made and inventive business practices are embraced.

Making a supply chain more resilient and making it more efficient are often diametrically opposed objectives. Managers have to make informed trade-offs when designing their supply chain networks. There are many methods available to quantify and optimise efficiency. Unfortunately the same cannot be said for vulnerability and resilience. We propose a method to quantify the impact that a supply chain's dependence on the underlying transport infrastructure has on its vulnerability. The dependence relationship is modelled using multilayered complex network theory. We develop two metrics relating to the unique collection of shortest path sets namely redundancy and overlap. To test the relationships between these metrics and supply chain vulnerability we simulate progressive random link disruption of the urban road network and assess the impact this has on Fully Connected, Single Hub and Double Hub network archetypes. The results show that redundancy and overlap of the collection of shortest paths are significantly related to supply chain resilience, however under a purely random disturbance regime they hold no predictive power. This paper builds a foundation for a new field of inquiry into supply chain vulnerability by presenting a flexible mathematical formulation of the multilayered network and defining and testing two novel metrics that could be incorporated into supply chain network design decisions.
