Presented at the 8th International Physical Internet Conference (IPIC 2021) 14-16 June 2021, Virtual, This research paper aims to present the main applications that have been performed in seaports based on 5G network communications, following a scoping review of available studies. The main applications that have been implemented in ports are presented, focusing mainly on improvement and automation of container terminal operations, vessel management and warehouse management. Such applications can support system multi-connectivity, sensor measurements, large-scale infrastructure monitoring and customizable network coverage, enabling the implementation of Physical Internet (PI) network. The outcomes of 5G applications implementation include increased efficiency of the port, providing flexibility and reliability to its daily operations, increased safety for the on-field employees, as well as control of the environmental impact and reduction of CO2 emissions. Further research opportunities are presented, towards the adoption of a wider operational framework based on 5G technology, the full terminal automation, the automation of procedures among different terminals, the provision of services tailored to specific stakeholder groups and the promotion of PI approach.

European ports are currently facing the challenge of adapting to the current trends in global trade and efficiently handling the increasing volumes placed on them. The aim of this paper is to present an innovative framework supported by disruptive technologies for cargo ports to handle upcoming and future capacity, traffic, efficiency and environmental challenges.The innovations to be implemented within the proposed framework will contribute to the Port of the Future objectives regarding reduction of port’s total environmental footprint associated with intermodal connections; the improvement of operational efficiency, and increase of data sharing and information visibility; and the promotion on the innovation in the port-urban context. Among the solutions presented, the model-driven tool for Real-time Control of port operations, the advanced Truck Appointment System and the Cargo Flow Optimization tool, aim to pave the way into interconnected port systems with information at various steps of the transportation flow. Overall, the proposed framework aims to develop models and tools which can support ports to improve their efficiency and gradually participate in a Physical Internet network.

Outsourcing is a trend that has penetrated many industries over the last years taking the form of offshore outsourcing in many cases. However the location decision that follows the offshore outsourcing or the offshoring decision is quite complex and almost impossible to be answered through a linear model. A series of frameworks have been developed attempting to facilitate the process above.The focus of this work is the analysis of the location decision making through the reflection of the existing literature and the example of a specific country, Greece. Greece is chosen as a dynamic environment where the recent economic crisis has provoked structural reforms at the country, affecting the attractiveness of the location. The analysis of country is based on an OECD recent survey while the comparison is made with the assistance of a specific location decision model.Based on the findings of this study, it can be claimed that the case of Greece is quite different compared to other countries at the past which have faced similar situations. Further the reforms that take place need more time in order to be projected and trigger the attractiveness of the location.

COREALIS proposes a strategic, innovative framework, supported by disruptive technologies, including IoT, data analytics, next generation traffic management, for modern ports to handle future capacity, traffic, efficiency and environmental challenges. Through COREALIS, the port will minimize its environmental footprint to the city, it will decrease disturbance to local population through a reduction in the congestion around the port. COREALIS proposes a bunch of solutions for the ports based on big data analytics: i) a predictive model for maintenance for the port of Piraeus ii) a cargo flow optimizer based on historical and current data for hinterland connection applying at the Port of Antwerp iii) an optimized Truck Appointment System based on an Estimated Time of Arrival through real time data.

Αντικείμενο της διπλωματικής αυτής εργασίας είναι η μελέτη ενός ZigBee ασύρματου δικτύου βιοαισθητήρων και η δυνατότητα διασύνδεσης του με μεγαλύτερα δίκτυα όπως το Ίντερνετ. Αρχικά γίνεται μια αναφορά στην χρησιμοποίηση δικτύων τηλεϊατρικής, στη σπουδαιότητά τους για τον άνθρωπο καθώς και σε ολοκληρωμένες λύσεις που έχουν προταθεί. Έπειτα παρουσιάζονται και περιγράφονται βιοαισθητήρες που χρησιμοποιούνται σε ένα WBAN όπως και η λειτουργία τους. Στη συνέχεια γίνεται εκτεταμένη ανάλυση όλων των επιπέδων του πρωτοκόλλου Zigbee/802.15.4 στοχεύοντας πιο συγκεκριμένα στη ζώνη μετάδοσης των 2,4 GHz και το πως αυτή μπορεί να χρησιμοποιηθεί κρατώντας υψηλό το QOS , απαραίτητη προϋπόθεση ενός δικτύου τηλεϊατρικής . Τέλος μελετώνται οι πιθανοί τρόποι διασύνδεσης δικτύων αισθητήρων και γίνεται προσομοίωση ενός TCP/IP δικτύου στο οποίο καταλήγουν τα δεδομένα τα οποία συγκεντρώνονται από μια σειρά αισθητήρων με σκοπό τη μελέτη της δυνατότητας χρήσης ενός τέτοιου συστήματος. Subject of this diploma work is to study a ZigBee wireless biosensor network and connectivity with other networks like the internet. Initially is made a reference to the use of telemedicine networks, the importance for man as well as integrated solutions that have been proposed. Then there are presented and described biosensors used in a WBAN as their function. Then is made an analysis of all levels of the protocol Zigbee/802.15.4 targeting the particular zone of 2,4 GHz and how it can be used while holding a high QOS. Finally are examined possible ways of interconnecting networks of sensors and is made a simulation of a TCP / IP where the collected data from the sensors end.
