Optimizing overseas container transportation: A case involving transatlantic ports:

This study focuses on the importance of the development of maritime container ports in the case involving transatlantic container transport in order to ascertain an optimal model of container flows between container terminals in the eastern coast of the United States and those in Western and Northern Europe. The model proposed by the authors is developed using the following eight key elements: transport infrastructure and suprastructure, use of intelligent information systems, economic growth, transport ecology, cargo flows, innovations, safety and security, and transport energy. The research builds mainly upon secondary statistics data analysis. The authors suggest that there is a close and strong connection between the development rate of maritime containers ports and the proposed model for transport optimization, which considerably influence the level of attractiveness of maritime container terminals.

Dynamic Optimization in Supply Chains

Production and stock optimization in supply chains representsextremely complex problem, because it determines the optimumquantity production in time. Due to their multilevelednature, those problems are mostly solved by application of differentmethods and models of dynamic programming. Theproblem addressed in this scientific debate refers to determinationof optimum quantity of production and stocks within thesupply chain in a certain period of time, as well as in eachsub-interval of the said period, but with the condition that theproduction and stock expenditure remains minimal and thatthe predetermined demand in every sub-interval and throughoutthe entire observation period remains satisfied.

Human Potentials Management in Transport

The main goal of this scientific study is to explore the significanceof human potentials management in micro and macrotransport systems, i. e. whether and to what extent do the humanpotentials represent the factor of growth and developmentof transport systems. The facts gathered by this study shouldrepresent quantitative starting points for viewing the specifics oftransport service productions and future movements on thetransport labour market, and the possibilities of informationtechnologies implementation in transport human potentialsmanagement optimisations, all with the aim of producing newand of improving the inherited comparative advantages of theCroatian transport systems.
