Should firms perform logistics services on their own or should they buy them from a logistics provider? Today’s global competition forces companies to re-evaluate their existing processes, technologies and services in order to focuse on strategic activities. Outsourcing is now increasingly used as a competitive weapon in today’s economy. External parties can often do job quicker, cheaper and better. This has resulted in an increasing awareness of the importance of the make-or-buy decision, the dilemma organisations face when deciding between keeping logistics services in house or purchasing them from an outside logistics provider. This article provides a make-or-buy decision process methodology that any manager can implement – whatever the size or industrial type of the organization. The make-or-buy methodology is one of the most critical strategic decisions within logistics outsourcing and should be taken in a structured and consistent manner. A practical guide to this decision is a step-by-step guide to addressing make-or-buy decision in a consistent and structured manner. The high-level steps are as follows: • evaluate whether outsourcing is right for your company; • determine exactly what functions to outsource and the performance expectations; • use a well-defined professional selection process to evaluate and select which provider(s) are right for the job. KEY WORDS: logistics, logistics outsourcing, make-or-buy decision, outsourcing methodology

In order to solve the system optimum dynamic traffic assignment problem, the whole link model with physical queue is used to formulate the single destination system optimum dynamic traffic assignment problem as a mixed linear program. A relationship between the cumulative curves and the wave speed presented by Newell (1993) is used to present a dynamic network model in considering spillback queue. And nonlinear constrains are relaxed into mixed linear constrains; the linear program software is used to solve the system optimum dynamic traffic assignment problem. A numerical example illustrates the simplicity and applicability of the proposed approach. KEYWORDS: Dynamic System Optimum Traffic Assignment; physical queue; mixed integer linear programming

With the European Union growing eastwards and with the establishment of important production facilities in the countries of Central and Eastern Europe, the hinterland potential is bound to grow even more. The strategic goal of the Port of Koper is to become one of the best ports in the Southern Europe, to develop from a handling port into a commodity distributional centre. Penetrating and exploiting these markets demands cooperation (integration) with the existing inland terminals (logistic centres) and establishing of new ones positioned between Eastern and Western Europe. This paper aims to present and analyse: (I) supply chains of the flow of goods through the Port of Koper to/from the countries of Central and Eastern Europe, (II) the current state and strategies to optimize the flow of goods, (III) market potential, investments in new terminals and capacities. KEY WORDS: Port of Koper, strategies, goals, supply chains, integration, new terminals, market potential, investments

One of the measures to increase road traffic safety in Croatia is the introduction of obligatory use of daily lights on vehicles in road traffic during driving, regardless of the visibility and the time of day. The paper describes the new original technical and technological procedure of analysing automotive light bulbs in order to find the traces of glass particles of the broken glass balloon in the marginal cases of action of small inertia forces generated as result of a traffic accident. Investigations of light bulbs in traffic accidents had been rarely done before; therefore the subject of this scientific research is the analysis of the light bulb filament used in automobiles to light the road ahead and to give light signals, i.e. all the light signalling devices on the automobile using the new technical and technological procedure by means of SEM/EDX method. The scientific research has improved the investigation procedure in analysing the light bulbs on automobiles in determining whether at the moment of the traffic accident the regulatory lights were switched on. In determining the responsibility of participants for causing the traffic accident, such a fact may sometimes be of crucial significance. KEY WORDS: traffic accident, light bulb, technical and technological procedure, lights in traffic, microscope, molten glass particles

The paper analyses the real-time detection of incidents in road traffic. A general model is presented of an integral road traffic incident management system. The paper presents the major incident detection methods. The detection procedure on open highway sections has been dealt with in particular. Adequate mathematical model has been defined, as the base for the realisation of the estimators of the traffic flow condition variables. The proposed method is the Extended Kalman Filter. The final part of the paper deals with an example for the realisation of the Incident Management Decision Support System (IMDSS). KEY WORDS: intelligent transport system, incident management system, traffic model in the status space, theory of estimation, extended Kalman filter, automatic incident detection, decision support system

In the forthcoming period the European air traffic management will handle double flight operations than today – from 1.7 to 2.1 higher traffic level in 2025 than in 2005 [1]. The problem of the European airspace fragmentation should be solved by the comprehensive dynamic harmonization programs, which can contribute to effective increase of airspace capacity and increase of air transport efficiency. The main objective of the development strategy refers to the implementation of reformation processes of the European air traffic management system through functional ATM1 regionalization. Encouraged by the Single European Sky project, and through airspace de-fragmentation, numerous projects have been initiated by Eurocontrol in cooperation with the European Commission. One of them is establishing of the Functional Airspace Block in South Eastern Europe. The implementation of regulatory, institutional and legal framework of the Single European Sky FAB2 would ensure the expansion of the European air traffic market to South Eastern Europe, counting over 500 million potential users [2]. Croatia and all the other countries in the region have to adopt the provisions of ECAA3 Agreement and EU air transport acquis in their national legislation. This paper specifies the main determinants of the strategic development as well as the key factors which influence the European air traffic dynamics. The paper elaborates the indicators and significant elements of the required ATM reforms in South Eastern Europe on the samples of six ANSPs according to ECAA Agreement and EU acquis. KEYWORDS: Single European Sky, European Common Aviation Area, Air Traffic Management, South Eastern Europe, Functional Airspace Block

The increase of market share of railway in cargo transport on Corridor X is considered a precondition in order to make railway operation cost-effective and commercially attractive to private operators. Railway sector has suffered damage during the war and the infrastructure needs modernization in order to create efficient and environmentally-friendly transport modes. The intervention is necessary in order to allow the railway network to be successful in the corridor competition. The forecasting model would be used to forecast the requirements for intermodal transport by the year 2018 on Corridor X using forecasting model for the future of the development of cargo transport requirements on Corridor X. KEY WORDS: intermodal transport, cargo flows, transport forecast

The paper compares the EU Postal Directives (97/67/EZ and 2002/39/EZ) in a consolidated text and the respective parts of the Croatian legislative frame with the aim of harmonising the national postal system with EU. Both regulatory frames are presented, as well as objectives and scopes, types of postal services (particularly the universal ones), reserved area, necessary conditions governing the provision of services, tariff principles, insurance of market competition through transparency of financing and separation of the accounting system, desired quality of universal services, harmonisation of technical standards and obligations of national regulatory authorities. By presenting individual chapters of the Post Directives, some specific solutions of the Croatian regulatory framework have been indicated and uncertainties which result from the comparison analysis of the European Postal Directives and the Croatian legislation as well as the influence of these documents on the postal traffic technology. KEY WORDS: EU Postal Directives, Croatian postal regulatory frame, universal services
