Use of an economic metaphor for a usage of the computer aided logistic organization leads to motivating self-interested parties to achieve mutual satisfactory and efficient outcomes. Efficiency, in this sense, is maximized when redistributing the trade surplus leaves everyone at least as well as before. Simulation of economic aspects of transport logistic chain is currently under the way at Rijeka College of Maritime Studies. The system consisted of 24 different types of organizations and 103 different documents interchanged in the supply chain.
The primary aspects were transaction costs and vertical integra¬tion using electronic aided logistics and electronic documents. The paper introduces results of the research showing savings up to 1,2 % of GDP for any country. The savings have been calculated for each organisation type, showing it's structural position in the supply chain.
