A multifaceted approach to assessing intermodal transport

Nehring Karol, Lasota Michał, Zabielska Aleksandra, Jachimowski Roland

Zeszyty Naukowe. Transport / Politechnika Śląska

2023

z. 121

141--165

The article presents the issues of land intermodal transport, taking into account their impact on the natural environment. The subject of the research is the use of the ELECTRE I method as a decision support tool in the assessment of various variants of transport, taking into account intermodal transport, i.e., transport on the initial and final sections of the route with the use of road transport and transport in the middle longest section by rail transport. This significantly reduces the emission of harmful compounds emitted into the atmosphere by the transport industry. In connection with the above, research on the possibility of choosing transport routes using mixed modes of land transport has been presented. The analyzed transport from point A to destination B considers two reloading operations at the land intermodal terminals. For each of the variants, indicators related to emissions from fuel consumption, the total time and cost of the process, the share of rail transport in the entire process, and the distance of road transport were calculated. The final analysis of the results shows that the following parameters had the most significant impact on the course of the research: the level of carbon dioxide emissions into the atmosphere and the total cost of the process for a given variant. Based on the conducted research, it can be concluded that the variant of transporting cargo from Rybnik to Świdnik with reloading at the PCC Intermodal terminals in Gliwice and the Lublin Container Terminal turned out to be the most advantageous solution.

The publication presents an example of the application of the selected method of multi-criteria consideration. The purpose of the research undertaken was to identify the leading technical and technological features of oversized low-loader combinations used in the structures of the Polish Army and units of the United States Army, and to select the most favorable decision option using the ELECTRE I multi-criteria method. The research area analyzed in the publication is very important from the point of view of military units, with emphasis on the ever-increasing total weight and dimensions of this type of combat vehicles used by the Polish Army. The article reviews the literature on the essence and importance of multi-criteria methods. Identification of technical parameters of vehicles used in the transportation of militaria was made, taking into account their individual equipment, necessary during the organization of transportation. In the second part of the article, a multi-criteria analysis of vehicle assemblies used in the movement of the heaviest combat units was carried out using the ELECTRE I method. The analysis of the results shows that the parameters that had the greatest impact on the course of the study were: maximum engine torques and the permissible weight of the transported load. The study indicates that the most favorable solution turned out to be the vehicle combination offered by the American company Oshkosh.

W publikacji przedstawiono przykład zastosowania wybranej metody rozważania wielokryterianego. Celem podjętych badań było wyłonienie wodzących cech techniczno-technologicznych ponadnormatywnych zestawów niskopodwoziowych stosowanych w strukturach Wojska Polskiego i jednostkach Armii Stanów Zjednoczonych oraz wyłonienie najkorzystniejszego wariantu decyzyjnego przy użyciu metody wielokryterialnej ELECTRE I. Obszar badawczy analizowany w publikacji jest bardzo ważny z punktu widzenia jednostek wojskowych, z naciskiem na ciągle rosnącą masę całkowitą oraz wymiary tego typu pojazdów bojowych wykorzystywanych przez Wojsko Polskie. W artykule dokonano przeglądu literatury dotyczący istoty i znaczenia metod wielokryterialnych. Dokonano identyfikacji parametrów technicznych pojazdów wykorzystywanych w przewozach militariów uwzględniając ich indywidualne wyposażenie, niezbędne w trakcie organizacji przewozu. W drugiej części artykułu przeprowadzono analizę wielokryterialną zespołów pojazdów stosowanych w przemieszczaniu najcięższych jednostek bojowych z zastosowaniem metody ELECTRE I. Analiza wyników wskazuje, że największy wpływ na przebieg badań miały parametry: maksymalne momenty obrotowe silników oraz dopuszczalna masa przewożonego ładunku. Przeprowadzone badania wskazują, że najkorzystniejszym rozwiązaniem okazał się zespół pojazdów oferowany przez Amerykański koncern Oshkosh.

Multicriteria analysis of the potential for industrial development within the counties of Aragon

To enable companies to favourably develop their business, with manufacturing, logistics or any other type of activity, industrial parks must be able to provide the facilities, physical space and industrial land to develop the basic infrastructure that organisations demand. The aim of this study is to determine how attractive different administrative regions (hereinafter, counties) in Aragon are for companies. Firstly, the attributes and factors that influence the decision for locating businesses have been identified via surveys with business people and company and economic agencies. Information was then collected from all industrial sites in the Autonomous Community of Aragon for each of the factors identified in the previous step, to evaluate the regions in terms of these location factors. We have used the ELECTRE I method, which is a multi-criteria decision technique for business location that provides a set of alternatives which "outrank" the rest and are therefore more attractive for investment..
