Currently Port of Klaipėda has been interlinked by ro-ro transit lines with Germany, Sweden and Denmark. It has been sought not only for improvement but also for development and expansion of the ro-ro market in order to answer continuously growing needs of clients. Lithuanian ro-ro liner shippers and operators although confronted by severe competition in ro-ro shipping market, strive to retain their position, conquer and manage new ro-ro markets. Yet it is to be mentioned that close cooperation with other transport industries and ro-ro terminals is not always attainable what consequently enhance the impact of factors affecting ro-ro transport and lessen attractiveness of such transportation, reduce cargo flow in general. Relevance of the problem. Considerable part of ro-ro lines are forced to close down soon after they are opened as having no prospects for they fail to attract sufficient freight and cargo flow due to multiple reasons like inadequate assessment and underestimation of advantages, shortcomings and risks (threats) and overestimated possibilities, insufficient research into cargo flow, inconsideration or failed acknowledgement of factors affecting ro-ro transportation. Therefore the relevance of the issue involved in this dissertation reveals not only for developing of new ro-ro shipping lines, but also for restructuring of existing lines and restoring of former ro-ro lines, it applies also in view of intended increase in competitiveness of ro-ro freightage...

The Escape Time Algorithm provides us with a means for "seeing" the filled Julia sets of Newton‘s fractals, but roots, (zeros) of the polynomial under investigation should be known. The Newton‘s method for finding roots of an algebraic equation is well known. Here in the paper the complex Newton method for finding roots of a complex polynomial is presented. The main difficulties, associated with implementation of this method in practice, are discussed, namely: construction of the set of initial points (first approximations of the roots), finding the basin of attraction for a particular root and so forth. Some experimental results are presented.
