DETCCM Networks Analyse Model Applied for Short-Sea-Shipping Opportunities Prospecting. Le Havre, Hamburg, Marseille and Valencia Port's Cases
Résumé
This paper aims to contribute to graphs and algorithmic general theory ans applications. The finality is to propose a valid framework to prospecting possible transport multimodal chains. Proposed model DETCCM, is founding on the concept of "equivalent Transport Distances" and on the algorithm of minimal distances adapted to can analyze superposed networks. The equivalent transport distances allow us to compare directly between different modes of transport respecting their own characteristics and the performances of modal vehicles and networks. The algorithm allows us to find the optimal transport combination, which is modeling as a chain. In this way, results show us the best combination to join two nodes origin/destination after analyze of all possible modal combinations between these nodes. DETCCM is a multi criteria model. Thus we could analyze the combined transport chains in function of different criterion as cost, travel time, pollution emissions or other applicable criteria or synthetic index. This flexibility of model make the results of "Optimal Combined Transport Chain" interesting for all transport actors as shippers, carrier companies, territorial managers or politics in function of their own priorities ans interests. The develop potential of this model is huge. As a first develop stage of model, we expose the results obtained in the case of Short-Sea-Shipping opportunities prospecting for the cases of four main European ports : Le Havre, Hamburg, Marseille and Valencia. This prospecting analyse consider two modal networks : sea and road. The results shows the main possibilities to develop Short-Sea-Shipping lines between ports of Western Europe, considering the four ports as obligates passage nodes. The road network include the 112 main cities and the sea network include the 57 main Ports in Western Europe. As pragmatically result, we defined the short-Sea-Shipping lines with more economically potential and we identified the principals partners ports of each of four analyzed ports. Finally, we do a qualitative interpretation of results and some recommendations to impulse the development of Short-Sea-Shipping. Today, ports all over the world compete fiercely to win the transoceanic traffics of goods and to secure the loyalty of main carriers companies. At the same time, Short-Sea-Shipping is a hide and almost an unsuspecting source of maritime traffics for ports.
