The North Adriatic cargo seaports of Rijeka, Trieste and Koper lag behind the highly developed North European ports operating as optimized logistics centers of effective logistics network in which these logistics centers are situated. For this reason, the whole logistic-traffic route that relying on business operations of the North Adriatic seaports runs the risk of decline in traffic and accordingly market marginalization. In order to get adequately the answer to the question of how to raise the competitive level of North Adriatic logistics port space, the doctoral dissertation has approached the problem of determination and finding a model that will defined the settings of the new North Adriatic logistics port system in concise and thorough way. The analysis of general port and logistics elements was the prerequisite for a systematic analysis of business operations and level of development of the North Adriatic cargo seaports, their position within the Central European logistics network, as well as for analysis of level of performance, efficiency and development of the European logistics network as a whole. The proposed new models of the North Adriatic cargo seaports in centre of Central European logistics network are the resultant of comprehensive analyses of the aforementioned factors, and these new models are made through an appropriate evaluation of numerous elements relevant to successful of logistics port system. New models of the North Adriatic cargo ports are based on parameters of logistic gravitational zones and elaborated on growth matrix and elements used for proposing of unique model have been extracted therefrom. Several measures and procedures have been proposed for implementation of the new model, and possibility of its successful application has been tested by SWOT analysis. Advantages of the new model of the North Adriatic cargo seaports in relation to existing logistics port business structure can be read out from the SWOT analysis, which in practice shows inefficiency and lack of competitiveness compared to the North European one.
