The work considers the notion and the importance of logisticsas an element of improvements in storing, distribution andtransport of goods. There is always room for improvements inthis segment of economic activities and they are necessary in orderto optimise the flow of goods from the manufacturer to theend user. The purposefulness and real efficiency of business logisticsis presented using the example of a Croatian company.Also, the importance of further development and implementationof logistics in Croatia is continuously being emphasisedthroughout this work.

In the cycle from production to consumption there is liquidcargo which is mostly transp01ted by sea. Optimisation oftanker dimensions since the sixties has required constructionand exploitation of ever bigger vessels and the tendmcy ofstricter responsibilities: 'objects of higher responsibility'. Today,liquid cargo makes up almost half of all the cargo transportedby sea. Transportation of such stagge1ing amounts isve1y complex both from the aspect of general safety during navigationand in operations at the te1minal, since such cargo representsharmful substances according to the SO LAS Conventionregulations (rule VII/2). The awareness of the threat to the humanenvironment, land, shores and sea, stimulates developmentand affirmation of ecology as science of very strict bansand requirements towards evety activity which may be a potentialsource of wider pollution. The effects of oil on the sea regardingcomposition and properties may be chemical, physicaland biological, disturbing as a rule the natural balance of theecosystem at all levels. Special significance lies in the study ofthe influence that oil, its products and surface active substances(dispersers) have on the lwvae and ova of sea organisms - themost sensitive phase of life cycle in the sea, which mostly live inpelagic environment.

This paper deals with takeoff procedure of various aircraftand rotorcraft types from the same runway. The three-typequeue, at three different holding positions i.e. the simulationmodel for these conditions has been created. Simulation analysisof resulting values determines the optimal start-up time foreach participam and its pwpose is potential reduction of fuelconsumption.

The article presents a principle layout of a modem HUMSalong with the basic system operating procedures. The articlealso deals with the impact of HUMS Oil aircraft maintenanceprocedures and economy, the impact on maintenance systemarchitecture and the implementation of cost-saving measures.The improvement of flight-safety as a consequence of HUMSapplication is also discussed.

Over the recent years the container feeder service is becomingan increasingly important element of containerisation. Thechanges in container flows caused by political changes in CentralEurope have resulted in a drain of a significant part of thistransport from the Adriatic to the North European ports. Theilztroduction of the container train Budapest - Rijeka, for theneeds of feeder service would mean a significant step towardsrevitalisation of the Rijeka transport route.With adequate government support, the Croatian sea-goingship operators will form the basic factor in the development ofcontainerisation and feeder service, and this will result in thereturnof the container transport to the ports of Rijeka and Place,thus at the same time improving the Croatian foreign trade exchangeand increasing the level of exploitation at the mentionedports, railway, agents, forwarding agents, and shipsowned by line ship operators.

Multidisciplinary character of traffic science in a widersense and science abouttransp01t in a narrower sense stipulatethe definition of semantic relation between the terms 'transpori'and 'traffic', as well as the meaning of conventional,combined and multimodal transpott, and some impottanttypes of traffic and transporl.Besides the definition of imporlant subjects about trafficand transp01t, for better understanding of the imparlance of financialratios of efficiency and stability for the transport corporationmanagement, the following are relevant facts of financialpolicy. This means the concept and imp01tance of financialpolicy which is composed of important subordinated policy.The most important objectives of financial policy areachieved by charging compensation for the given transp01t services.The compensation is determined based on tariffs as directconsequence of tariff policy.Successful deduction (derivation) of financial ratios of efficiencyand stability in the transporl corporation business requiresqualitative financial reporls, composed and processed insuch a way that they are adequate infO/mational basis for furtheruse.Imp01tant ratios of efficiency and stability deduced from financialreports oftransp011 corporation could be classified intothe following groups: liquidity, debt, activity, economy, profitabilityand investment ratios. Finally, standardised ratios deducedfrom adequately prepared financial rep011s could beused by the management oft he transp01t corporation as well asby other users.

Analysis of the traffic flows of postal items is an impmtantprerequisite in improving the technology and/or redesigningpostal network.The basic modelling sequence is to optimise the traffic(postal) network structure for the identified traffic demand andthe determined traffic flow matrix, respecting relevant requirementsand limitations.The paper provides elements of a general approach to solvingthe problem and develops a concrete traffic matrix with thedata on postal-item flows. Elements are indicated for redesigningof postal network, which include the positioning of nodesequipped by systems of automatic handling of postal items.
