    This thesis addressed to use of Agent-Based Modelling (ABM) for the development and implementation of the import process of goods in a port that is suitably applied to help, plan, structure the development of the port model. The main goal of the modelling and implementation was to reach to fruition as more organized, fast and efficient complex logistics network, through development policies. To this purpose, I developed an agent-based model (ABM) of a port that is populated by the real main actors (stakeholders) whose are involved in the port activities such as maritime, customs, financial police etc. The model of the port simulates the actual port processes, i.e. acceptance of the goods, sending them, controlling of the legality, or not to import goods, the transportation planning etc. Agent-based models (ABMs) are being used in modelling in economies as complex systems that is a relatively recent approach in economies [62]. It has increasingly been attracting many scholars belonging to several sub-fields, becoming both a complement and a substitute for more traditional economic-modeling methodologies [62]. We can mention that ABMs are considered as a valid and effective competitor of standard Dynamic Stochastic General Equilibrium (DSGE) models in macroeconomics [26]. The main advantages of using ABMs arrive two main additional values if we compare it with its equivalent systems. ABM provides more descriptive richness, as they characterize ecologies of agents, locally interacting through non-obvious network structures, learning using incomplete information, and competing within imperfect markets. Second, the modeler developing an ABM has typically more flexibility in both input and output validation of its model [34]. Ports have an integral role of our economy, they are strategic places of exchange, and especially over the last few decades and with the phenomenon of globalization, the ports are a reality in continuous movement and growth. Therefore, they are operating places of extreme complexity, especially in their logistics functions of transport management. The thesis discusses the business process is implemented for developing a computer supported management tool to handle the port activities flow. The tool is designed for the integration in a virtual infrastructure that allows an advanced operational management of port traffics. By modelling the time documentation according to the specification of the Genoa case, the business case of the port of Genoa is tested. Results show that the mechanism implemented simulates the actual process. Moreover some bottleneck are discovered, such as delays to the handling of the containers and queues formation due to missing documentation or documentation with errors or not ready

    Simulation is a decision support technique that is often used to represent systems of interest and to experiment with them. Multi-Agent Simulation (MAS) is increasingly being used for modeling systems that comprise of autonomous and interacting system components. In such systems, the interactions among the underlying system components may be dependent on their spatial characteristics (e.g., dimension and location in three-dimensional space). The work presented in this paper describes an agent-based approach to spatial modeling through the use of a case study in container loading. The contribution of this paper is the demonstration of the feasibility of using MAS for spatial, proximity-based modeling, wherein not only agent behavior but also their physical dimension and their location in the three dimensional space are key considerations

    Transport of dangerous goods by sea

    Within maritime transport dangerous goods count for about 50%. According to the general name, they present different types of risk and, therefore, dangers to life of all kinds. This dissertation is a, study of some aspects of the transport of dangerous goods by sea. The classification criteria are examined since classification is the gateway through which certain goods enter into a special domain governed by specific rules. As the sea mode of transport handles very large quantities of dangerous goods and, sometimes, for long periods of time, the safety requirements for ships are analyzed as to ensure the safe movement of such goods. Within the transportation chain the port is, probably, the most sensitive link. The aspects of entry procedures, storage and segregation, checking, emergency response, and national regulation for port areas are examined. To meet the requirements for emergency response, guidelines for contingency planning are given. All operations of the management of dangerous goods are carried out by people. Safety relies largely on them. Special attention is paid to the training of the people involved and the ways to achieve good results are shown. The final chapter is intended as a suggestion as to how the national regulations should be designed and what they should contain. The necessity to harmonize regulations pertaining to different modes of transport is emphasized in the conclusions

    HADES: A multi-agent platform to reduce congestion anchoring based on temporal coordination of vessel arrivals—application to the multi-client liquid bulk terminal in the Port of Cartagena (Spain)

    Get PDF
    Ports are key factors in international trade, and new port terminals are quite costly and time consuming to build. Therefore, it is necessary to optimize existing infrastructure to achieve sustainability in logistics. This problem is more complex in multi-client port terminals, where quay infrastructure is shared among terminal operators who often have conflicting interests. Moreover, the berth allocation problem in liquid bulk terminals implies demanding restrictions due to the reduced flexibility in berth allocation for these types of goods. In this context, this paper presents HADES, a multi-agent platform, and the experience of its pilot use in the Port of Cartagena. HADES is a software platform where agents involved in vessel arrivals share meaningful but limited information. This is done to alleviate potential congestion in multi-client liquid bulk terminals, promoting a consensus where overall congestion anchoring is reduced. A study is presented using a mixed integer linear program (MILP) optimization model to analyze the maximum theoretical reduction in congestion anchoring, depending on the flexibility of vessel arrival time changes. Results show that 6 h of flexibility is enough to reduce congestion anchoring by half, and 24 h reduces it to negligible values. This confirms the utility of HADES, which is also briefly described.The authors would like to thank Port Authority of Cartagena for data supplied, and terminal operators of docks E010 and E011 for their suggestions

    An Agent-based Approach for Improving the Performance of Distributed Business Processes in Maritime Port Community

    Get PDF
    In the recent years, the concept of “port community” has been adopted by the maritime transport industry in order to achieve a higher degree of coordination and cooperation amongst organizations involved in the transfer of goods through the port area. The business processes of the port community supply chain form a complicated process which involves several process steps, multiple actors, and numerous information exchanges. One of the widely used applications of ICT in ports is the Port Community System (PCS) which is implemented in ports in order to reduce paperwork and to facilitate the information flow related to port operations and cargo clearance. However, existing PCSs are limited in functionalities that facilitate the management and coordination of material, financial, and information flows within the port community supply chain. This research programme addresses the use of agent technology to introduce business process management functionalities, which are vital for port communities, aiming to the enhancement of the performance of the port community supply chain. The investigation begins with an examination of the current state in view of the business perspective and the technical perspective. The business perspective focuses on understanding the nature of the port community, its main characteristics, and its problems. Accordingly, a number of requirements are identified as essential amendments to information systems in seaports. On the other hand, the technical perspective focuses on technologies that are convenient for solving problems in business process management within port communities. The research focuses on three technologies; the workflow technology, agent technology, and service orientation. An analysis of information systems across port communities enables an examination of the current PCSs with regard to their coordination and workflow management capabilities. The most important finding of this analysis is that the performance of the business processes, and in particular the performance of the port community supply chain, is not in the scope of the examined PCSs. Accordingly, the Agent-Based Middleware for Port Community Management (ABMPCM) is proposed as an approach for providing essential functionalities that would facilitate collaborative planning and business process management. As a core component of the ABMPCM, the Collaborative Planning Facility (CPF) is described in further details. A CPF prototype has been developed as an agent-based system for the domain of inland transport of containers to demonstrate its practical effectiveness. To evaluate the practical application of the CPF, a simulation environment is introduced in order to facilitate the evaluation process. The research started with the definition of a multi-agent simulation framework for port community supply chain. Then, a prototype has been implemented and employed for the evaluation of the CPF. The results of the simulation experiments demonstrate that our agent-based approach effectively enhances the performance of business process in the port community

    Dissertação de Mestrado em Ciências EmpresariaisUm porto é um centro de confluência de vários modos de transporte, os quais permitem a movimentação das mercadorias do tecido empresarial localizado na zona de influência desse porto, designada de hinterland. Os portos, especialmente os de maior dimensão, podem também servir a movimentação de cargas entre navios de diferentes rotas marítimas. A fluidez das operações dos meios de transporte e da movimentação das mercadorias são factores essenciais na competitividade de um porto e a boa gestão da informação é uma das componentes importantes neste âmbito. Contudo, a diferente caracterização dos diversos meios de transporte, a multiplicidade de actores envolvidos na intermodalidade e na logística portuária e as assimetrias culturais e de nível de desenvolvimento tecnológico e de simplificação de procedimentos das autoridades representantes do interesse público no porto e das diferentes entidades privadas envolvidas no negócio portuário, dificultam o desenvolvimento de um modelo de relacionamento integrado, ágil e sob suporte electrónico. A filosofia “Single Window” para a gestão da informação nos portos tem apresentado bons resultados na componente isolada do transporte marítimo que tem características muito próprias, considerando-se absolutamente determinante aplicar esta filosofia a todos os meios de transporte e a toda a logística portuária. A fluidez da informação na intermodalidade é ainda uma realidade incipiente e o presente trabalho de projecto aborda esta problemática, fazendo uma análise crítica à situação actual e propondo um modelo possível de desenvolvimento, através da conceptualização de uma solução integrada para os portos, sendo o conceito simultaneamente estudado na sua aplicação à realidade do Porto de Sines e à sua área de influência. Os benefícios dos resultados deste projecto são ao nível da gestão operacional do porto e do planeamento da actividade dos transportes no seu seio e no hinterland servido, bem como ao nível da informação de apoio à decisão, esta com um caracter mais analítico e estratégico, com maior horizonte temporal de aplicabilidade.A port is a confluence point for the various means of transport, responsible for the handling of the goods pertaining to the industries and other sort of companies located within its area of influence, which is called hinterland. The ports, specially the major ones, may also serve the handling of cargoes between ships from different maritime routes. The agile handling of ships and cargoes is a key factor for the competitiveness of a port, and the information management is ever more a strategic issue within this scope. Nevertheless, the different features of the various means of transport, the multiple players involved in port intermodality and logistics, as well as the cultural, technological and procedures simplification asymmetries of both the authorities representing the public interest inside the port and the private parties involved in the port business, offer difficulties to the development of an agile and electronic integrated relational model. The “Single Window” philosophy implemented for the management of port information has been achieving very positive results, as far as maritime transport concerns (a sector with very specific characteristics), being absolutely imperative to apply this philosophy to all the means of transport and port logistics. The agility of information in Intermodality is still an incipient reality, and the present project takes a careful look at this problematic, by making a critical analysis to the present situation and presenting a possible development proposal, through the conceptualization of an integrated solution for ports, being the concept simultaneously studied to be applied to the Port of Sines and the area under its influence. The benefits resulting from this project will be reflected on the operational management of the port, on the planning of transports activity within itself and on the related hinterland, as well as on the information supporting decision-making, providing more analytical, strategic and long-term applicability data

    Sines industrial and logistics zones: FDI determinants applied to Sines and its peers

    Get PDF
    The goal of this case study is to identify the FDI location determinants according to the most recent scientific studies and match those location determinants with the ones that can be found at Sines’s Cluster. Firstly I had to define the main competitor countries and in order to keep things simple I only chose six countries: Germany, Netherlands, Spain, Poland, Egypt and Morocco. The countries Spain, Egypt and Morocco are direct competitors for FDI attraction while Germany and Netherlands compete in terms of containers transhipment. The information was gathered by searching on database like OCDE, World Bank and Bloomberg but also by talking with AICEP Global Parques and with Port Authority of Sines. From my theoretical research reducing total costs of the supply chain is crucial nowadays therefore Portugal can win from this since has a better relation between labour costs and qualified labour than Spain. Morocco has a poor infrastructure reducing its attractiveness but the labour is low qualified and cheap therefore might be good for labour intensive industries. Regarding the Eastern Europe countries, after analysing the location determinants they are inferior to Portugal. Germany and Netherland are better than the rest of the countries analysed in almost all aspects, except in labour costs. Portuguese Government should try to lower Tax in order to increase the competitiveness of the cluster versus the Eastern Europe clusters and also should work to attract a logistics third party in order to increase the efficiency of the cluster.O objectivo deste caso de estudo do Cluster de Sines é identificar os determinantes de localização de acordo com a pesquisa mais recente e comparar com os determinantes de localização que o cluster de Sines tem. Em primeiro lugar foi necessário definir os países que competem directamente sendo restringidos a seis: Alemanha, Holanda, Espanha, Polónia, Egipto e Marrocos. Os países Espanha, Egipto e Marrocos são os principais concorrentes de Portugal em relação à atracção de investimento directo estrangeiro já a Alemanha e Holanda são concorrentes em relação ao transporte de contentores (transhipment). A informação foi recolhida através da pesquisa nas bases de dados da OCDE, Banco Mundial e Bloomberg mas também através de entrevistas com a AICEP Global Parques e Autoridade Portuária de Sines. Com base na pesquisa teórica reduzir os custos totais da cadeia de abastecimento é fundamental e Portugal pode ganhar com isso pois tem melhor relação custo da mão-de-obra versus qualidade da mão-de-obra que a Espanha. Em relação a Marrocos, as infra-estruturas são fracas o que reduz a atractividade deste mas a mão-de-obra é barata e pouco qualificada o que é ideal para indústrias intensivas em mão-de-obra. Quanto aos países do leste da Europa tem uma atractividade mais baixa que Portugal quando considerados todos os determinantes de localização. Já a Alemanha e Holanda são melhores que os restantes Países analisados em todos os aspectos expecto nos custos de mão-de-obra. O Governo Português precisa de reduzir os impostos para que o Cluster de Sines consiga rivalizar com os restantes clusters concorrentes e também devia debruçar-se sobre a necessidade de um operador logístico no cluster de forma a aumentar a eficiência do mesmo
