Opis:
A growing ecological awareness in modern societies, legal regulations aiming at a reduction of waste storage and economic benefits that we can have from recycling of used products led to a situation that the creation of recycling networks has become an important issue, particularly in developed countries. The paper presents issues related to the design of recycling network whose purpose is to collect from the last owner, dismantle and properly recover end-of-life vehicles. In order to fulfil the ecological requirements and also efficient management of the whole recovery process, the conceptual framework of a reverse logistics network is presented. The collecting of vehicles, dismantling and following processes of shredding and treatment in material recycling facilities are considered jointly. Then a mathematical model is developed which minimizes the costs of setting up the network and also the relevant transportation costs. Because of the complexity of the model, a solution methodology based on the evolutionary algorithm is proposed which enables achieving good quality solutions in a reasonable algorithm run time. In particular, the participants and the flows in the recycling network and visualisation of the results for flows between dismantlers and plastic recycling facilities are presented in the paper.

Opis:
Recycling is a final stage closing the life cycle of vehicles. The quality of this process affects the combined impact of automobiles on the environment. Recycling networks differ in the level of efficiency due to the differences in how the recycling system is organized, their environment, and the characteristics of the entities taking part in recycling process. The article presents an algorithm of a method for assessing the effectiveness of a vehicle-recycling network, which can be used in a comparative analysis of networks, or for evaluating changes over time. A set of indicators relating to the technical, economic, environmental, and social aspects was proposed. The article presents the variety of aspects involved in assessing, the efficiency of a vehicle-recycling network the best solution seems to be the inclusion of selected indicators for the assessment model, which will also act as a tool to assess the state of the network and conduct rankings of available solutions. The model for assessing the efficiency has to be preceded by determining the purpose and scope of the assessment and analysis of available evaluation tools.

The article presents the results of road tests of the passenger car. The aim of this study was to determine the effect of variations in the vehicle braking methods on the carbon dioxide emissions. Inhibited using the gear ratios increase – less gear and using motion resistance while driving a rundown, in addition to using the brake system in the final stages of journeys made. The use of engine braking by drivers as a result of the reduction gear, for example during transport to the intersection, traffic light, railroad crossing, in place of the drive by coasting is particularly emphasized by the promoters of eco-driving. It is raised the issue of avoiding unproductive, from the viewpoint of the work efficiency of the engine, the engine idle speed. The verification of environmental aspects of the use of engine braking was made because of the testing under real traffic conditions. Test drives were carried out at the measuring section, free from traffic. The test vehicle accelerates to a speed of 50 km/h, and then two ways of the speed deceleration were used. The values of the concentration of harmful carbon dioxide in the exhaust gases were achieved by using a mobile apparatus for testing exhaust emissions.

The paper presents selected aspects of the evaluation of the effectiveness and risks of the logistics chain that supports the enterprise. It was assumed that the logistics chain includes all activities associated with the flow of materials from the sourcing of raw materials for sale to the ultimate purchaser of the product and the disposal of used products. It was found that the elements of the supply chain are usually unstable which generates difficulties in determining the appropriate level of the risk of the chain. The paper presents a formal record of risk and performance. There is proposed determination of the effectiveness of individual links of the logistics chain. The task of the logistics chain is to provide goods from producers to the final customers, thereby making available these goods in a place and time suited to the needs and expectations of customers. The movement of goods in the logistics chains is determined by the sequence of interrelated actions. In the logistics chains, many entities are involved to different extents. This determines the spatial distribution of different configuration of individual users of the whole logistics chain. In particular, example of a logistics chain of production company, stages of the procedures for quantitative risk analysis, the problems in the logistics chains, assessment of the risk of the task in the logistics chain, the concept of risk, effectiveness and risk in logistics chains are presented in the paper.

This paper presents the preliminary concept research to develop the test used in the measurement of emissions in real traffic conditions for passenger vehicles. Work based on the lack of legal solutions for determining the environmental performance of light vehicles – as opposed to heavy-duty vehicles for which such regulations have specified. The elaboration is to compare the emission test used in clinical approval of passenger cars, while the synthesis of the results obtained under different conditions road tests. The intention is to develop a test for assessing the ecological vehicle in real traffic conditions, where restrictions will only drive type (gasoline engine, diesel engine, hybrid vehicle), which is consistent with the requirements of the certification tests. The result should be the foundation for the development of the test in terms of: the duration, to determine the operating conditions and vehicle and proposals for emission limit values.

Opis:
The dynamic development of transport recorded in recent decades is an important factor in the economic development of the world on the one hand, and on the other hand, it is a significant source of nuisance and environmental problems. The adverse impact of transport can be felt both in the natural environment and in society, where the dynamic development of this sector has enabled significant civilization development, with the effects varying depending on the level of economic development, the degree of advancement and use of the various transport sectors, geographical location (including climate), and also the sensitivity of the elements of the environment. Considering contemporary transport hazards, it is important to prevent them from occurring, and when that is not possible – limiting their impact on the environment and reducing the scale and extent of negative impacts. In the article, the environmental and social nuisance of transport of goods loaded in semitrailers was analysed. The transport of semitrailers using intermodal wagons pulled by the diesel locomotive in accordance with the assumptions adopted in the railway with the maximum length of train composition was taken into account.

With the invention of specialized, portable research equipment, construction of which enabled road tests of vehicles, it has become possible to verify benefits ensuing from application of eco-driving rules outside the laboratory – the test stand measurements. Test of the vehicles’ operation in terms of ecology are essential especially in case of toxicity of exhaust gases in dynamic, transient conditions of engine operation. Despite the attempt to reflect those conditions in dynamic research tests, it is not possible for fully reconstruct real conditions of operation of vehicles of different homologation categories. Due to this fact in recent years, the biggest research potential in automotive industry has been focused right on the road tests of vehicles in real traffic conditions. The article presents the results of measurements of exhaust emissions of passenger car in real traffic conditions. The aim of this study was to initial verification how the driving style influences on the carbon dioxide emissions from vehicle engine and fuel consumption. The determinants were the measurements of the concentration of CO2 emitted to the atmosphere from the power unit of the tested vehicle. In the measurements, a portable exhaust emission analyser was used.

Background: The role of air transport in the economic development of a country and its regions cannot be overestimated. The decision concerning an airport's location must be in line with the expectations of all the stakeholders involved. This article deals with the issues related to the choice of sites where airports should be located. Methods: Two main quantitative approaches related to the issue of airport location are presented in this article, i.e. the question of optimizing such a choice and the issue of selecting the location from a predefined set. The former involves mathematical programming and formulating the problem as an optimization task, the latter, however, involves ranking the possible variations. Due to various methodological backgrounds, the authors present the advantages and disadvantages of both approaches and point to the one which currently has its own practical application. Results: Based on real-life examples, the authors present a multi-stage procedure, which renders it possible to solve the problem of airport location. Conclusions: Based on the overview of literature of the subject, the authors point to three types of approach to the issue of airport location which could enable further development of currently applied methods.
Wstęp: Transport lotniczy obecnie odgrywa ważną rolę, jeśli chodzi o rozwój gospodarczy zarówno kraju, jak i danego regionu. Ewentualna decyzja o jego lokalizacji powinna w maksymalnym stopniu spełniać oczekiwania interesariuszy. Niniejszy artykuł podejmuje tematykę związaną z wyborem lokalizacji portów lotniczych. Metody: W artykule przedstawiono dwa główne ilościowe nurty (podejścia) związane z problematyką lokalizacyjną portów lotniczych (PL), tj. problem optymalizacji wyboru lokalizacji PL oraz problem wyboru lokalizacji spośród z góry zdefiniowanego zbioru. Pierwszy z nich związany jest z programowaniem matematycznym i sformułowaniem problemu jako zadania optymalizacyjnego drugi natomiast zszeregowaniem wariantów Z uwagi na różne podłoże metodyczne autorzy przedstawili wady i zalety obu podejść oraz wskazali tą, która ma obecnie swoje praktyczne zastosowanie. Rezultaty: W artykule, opierając się na rzeczywistych przykładach, zaprezentowano procedurę wieloetapową pozwalającą na rozwiązywanie problemu lokalizacji portów lotniczych. Wnioski: W artykule, wskazano na bazie przeglądu literaturowego trzy koncepcje podejścia do problematyki lokalizacji PL, dzięki którym możliwe byłoby rozwinięcie obecnie stosowanych metod.
