The use of BDA brings the digital transformation of FSCs closer providing sustainable implications and added value to their operation. Harnessing BD’s potential is becoming more and more relevant in addressing the constantly evolving complexities in food systems. However, the field of BD applications in the FSCM domain is severely fragmented and relatively “primitive”. The present research is one of the earliest attempts to recognize and present a comprehensive analysis for the BD applications across different segments of FSC proposing a conceptual framework that illustrates the role of BD in a data-driven FSCM environment.

In particular, we investigate whether these countries exhibit the tendency to catch up, in terms of logistics performance, with the leader country, using methodologies of “convergence analysis” appropriate for the notions of stochastic convergence and β-convergence and perform Granger-causality tests among a catching up variable (the LPI of each country relative to the LPI of Germany), Trade Openness and economic growth. The findings reveal rather weak evidence of catching-up effects with Germany. As far as causality is concerned, trade and economic growth further enhance the global tendency in logistics performance to catch-up with the dominant Germany while convergence in logistics is found to directly support economic growth but not trade.

Design/Methodology/Approach: We analyze the dynamic linkages among the Logistics Performance Index (LPI), trade openness as a percentage of the Gross Domestic Product (GDP), as well as the GDP growth based on a sample of 39 countries worldwide over the period 2007-2018. More particularly, we assess the significance and the direction of the detected causal effects among the three variables both in the long and the short run, using panel econometrics methodologies, namely, panel unit root tests, pooled mean group (PMG) models, and the Toda-Yamamoto approach to Granger-causality analysis. Findings: The findings support that both international trade and logistics performance constitute driving forces of economic growth. Moreover, it is demonstrated that the effects of the logistics' sector on international trade are not direct but only through economic growth. Practical Implications: The direction of causality is deemed quite important due to its strategic policy implications. A causal relationship running from the logistics and transport sector to trade investments in logistics and transport would cater for economic growth through increased trade. Policy makers should then adopt various policies aiming to promote or facilitate exports. Originality/Value: Causal effects and more specifically the direction of causality between the transport infrastructure and economic growth have not been sufficiently studied in existing literature. Furthermore, only few studies provide some general evidence of a positive correlation between better logistics and increased trade. In our paper, we aim to further investigate the dynamic relationships between international trade and the logistics and transport sector.

Airport decision makers should be able to cope with multiple – even conflicting – objectives and priorities assigned by various stakeholders. The assessment of the airport performance requires a deep understanding of the manifold performance aspects supported by advanced modelling capabilities. A wealth of decision support models and tools have appeared in both literature and practice, however, most addressed only partial aspects of the airport performance and exhibited several deficiencies with the most important being the clear lack of integrated modelling capabilities. This chapter presents the development of a system (SPADE) that will not only capture the manifold aspects of airport performance, but will also deploy a decision-oriented approach capable of analysing at a reasonable effort and at various levels of detail (e.g. strategic, tactical) the trade-offs among airport performance measures, entities, or elements. The objective of this chapter is twofold: (1) to introduce the structure and constituting elements of the SPADE system and (2) to demonstrate its decision support capabilities under ‘real-world’ conditions by means of two applications for strategic (Athens International Airport) and operational/tactical decision making (Amsterdam Airport Schiphol).

Travelers, whether leisure or business travelers want on the top of the attractions that a given destination offers, a fast, flexible, and convenient transport mean(s) to reach it, as well as other value added logistical information services. As a matter of fact, the provision of real time information constitutes a value added service (VAS) for the traveler that could more effectively cope with the stochastic elements and the dynamic nature of the intermodal system. In other words, what travelers in general, and tourists in particular expect are services that: i) are customised to their individual needs and preferences, ii) are available to them in a timel...
