With the globalization of market the production processand the life-cycle of the products have shortened by increasingthe expectations of industry for ''iust-in-time' logistic solutions.At the same time the competition on the global markets has increasedthe number of 'players' and the objectives of purchaseand distribution chains. The objective is to develop the framefor optimal integration of different transport modes thus facilitatingmaximally efficient and cost-effective usage of the transportsystem through user-oriented 'door-to-door' transportand to stimulate by this service the competition among transportoperators.

Logistic processes condition more and more the rationalizationof time required for manipulation of goods (loading,unloading, storage). The customs representation costs that arethe result of loss of time due to the customs procedures exclusivelyduring the working hours of the customs office affect alsothe total logistic costs, and may be significantly reduced by applyingthe privileged procedures in import and export.

Outsourcing has become increasingly popular in recentyears, and is often quoted as a means of coping with rapidchanges in technology and in the business environment. Thescope of third -party logistics may range from a relatively limitedcombination of activities (e. g. transportation and warehousing)to a comprehensive set of logistics services. The authorsfirst define the reasons for outsourcing with the emphasis onbusiness logistics. They particularly point out the motivationsfor logistics outsourcing, the possibilities of logistics outsourcing,and they present the process of outsourcing partner selectionas well. Finally, they analyze the specific issues of logisticsservice's perceived value in outsourcing logistics activities onthe basis of the survey carried out in Slovenian companies. Thepurpose of the survey was to measure the customers' perceptionof different characteristics of logistics provider which can be decisivewhen manufacturing firms are trying to make a decisionwhether to outsource and which logistics provider to select. Thepaper creates a framework for the selection of the importantand perceived characteristics of logistics provider relevant tocustomer in the process of the logistics supplier selection.

The rolling stock of the Croatian Railways (HZ) for thepassenger transport has reached a very low point of reliability,which for the moment still guarantees travelling safety. Besides,the Croatian Railways are facing an important moment of applyingthe new Law on Railways which places the commercialsector of the system directly on the market. Within the modernizationprocesses at the Croatian Railways 8 tilting trains DMB7124 have been purchased, which in VR 2003/2004 operatedon the Zagreb-Split-Zagreb relation, implementing the newJCN brand. The work deals with the analysis of the technologyapplied on JCN trains, as a certain novelty compared to the previoustechnological solutions that existed at the Croatian Railways.

Recent developments have shown revolutionary progress inthe areas of information technology, logistical science andinternationalisation of business. These facts and the elementsinvolved strongly influence the methods of production and provisionof services thanks to an i'epressibly growing speed ofdata and information transfer and surmounting the culturaland geographical obstacles, which has given rise to new conceptsof business process optimisation in overcoming the distancein space and time. The result of that development weretwo concepts in the business world, the Just in Time (J!T) conceptand its integral part 'Quick Response': whose origins arein the Far East, in Japan, in the automotive industry. Thebreak-through of these concepts and their fast spreading toother spheres of the world economy can be attributed to theiroverwhelming efficiency. Both concepts aim to release the capitaltied in inventories, and to reduce them, avoiding thus anysurplus inventories.

From the season 2005!06 a new dynamic model for the operationof the Winter Service in the Republic of Croatia will beused. The old model was based on three levels of readiness, andthe roads were categorised primarily according to their administrativedistribution. The new dynamic model has three levelsof readiness, while the first level is further divided into two servicelevels. The road is classified to a certain readiness and servicelevel according to the traffic, climate and economic conditions.The new model splits the cost structure into fixed and variablecosts. The investor wants to keep the fixed costs at a minimal/eve~ which will guarantee proper readiness for quick intervention.The investor wants to ensure a technological infrastructurefor quality cleaning of roads is created. The capitalcompanies want larger fixed costs to ensure certain profit, anddefined fixed costs enable them to asses the profitability of theWinter Service operation. Such structure fonils the followingrelationship: in mild winters the capital companies 'profit' andthe investor 'loses', and vice versa for cold winters. Mathematically,such relationship should be treated as a finite strategictwo-player game.This paper will show the model needed to forecast fixedcosts in the new dynamic model for operation of Winter Ser·vice, through consideration of connection of linear programmingand the matrix game theory, to study the problem in parallel,from the standpoint of both players.

A great many factors determine airside capacity. In the firstgroup are those factors correlated with characteristics of manoeuvringarea such as number, layout and location of runwaysand taxiways. In the following group there are elements correlatedwith flight operations such as arrival, departure, touchand go operations and also the factors related to the aircraftsuch as weight, separation and wake vortex separation criteria.In the last group there are all other elements such as meteorologicalconditions and restrictions, ecological conditions, airtraffic control skills and equipment, etc.This paper presents a detailed description of runway occupancytime in arriving and departing flight operations and indicationsfor possible improvements

The paper presents medical emergencies during the flighttime. The focus is on the most common types and causes ofthese emergencies. World indicators show an increase in thepassenger number and accordingly, an increased number ofemergency conditions and interventions. Lately, the larger aircrafthave been produced, with larger number of seats and thatleads to the increase in emergency medical interventions duringlong intercontinental flights. A typical sequence of events duringmedical interventions in aircraft is presented. Elderly passengersand those who have known chronic diseases have totake care about their condition by consulting the physicians,whose main scope of work is aviation medicine.
