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.

Opis:
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.

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.

Opis:
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.

Opis:
A scheme has been developed to be utilized for solving the interaction between wing aerodynamic loads and the flexibility of wing structures under a quasi static assumption. The interaction is implemented through a link between the nodes of finite element model and the grids of transonic small disturbance model. The particular finite element responses, namely translational displacement vectors (TDV), are utilised for reconstructing the deflected wing surfaces. So in each iteration, the updated surfaces are involved as the parent for regenerating the TSD grids. The criteria of the Euclidean norm is applied for evaluating the convergency of aero-structure interaction. Catia-V5, is fully employed to manage three dimensional geometries for developing the model of wing structures, calculating grids and aerodynamic loads, as well as for reconstructing the updated wing surfaces. Numerous functions and objects of Catia are employed by conducting particular accesses via component object models using Microsoft Visual Basic.Net. A case study is excersized to demonstrate the interaction in transonic speed. The results shown that the scheme is very good in the way performing the interaction in quasi static condition. The utilization of TDV for generating the deflected wing surfaces indicates the capability of high fidelity deformations with respect to the complexity of finite element model

The paper presents selected aspects of a design of a proecological transport system. The necessity of designing proecological transport systems results from forecasts of transport demand and adaptation of the infrastructure to the standards and requirements of the EU. The European Commission pays special attention to the need for sustainable and environmentally friendly transport. Warsaw University of Technology in collaboration with Poznan University of Technology performs a research work concerning the development of an environmentally friendly transport system - Project EMITRANSYS. One of its stages is a development of a mathematical model taking into account the minimization of both the negative impact of transport on the environment and the transportation costs. The paper proposes a general formulation of the mathematical model of a proecological transport system (MEST) including the boundary conditions. A function of criterion minimizes the emission of harmful exhaust components resulting from traffic distribution in a network. The point elements of the infrastructure in a model represent places where the infrastructure parameters change, i.e. crossroads, narrowed roads or reduced speed areas. In addition, the structure of the vehicle fleet embraces the characteristics of the emission levels of different types of exhaust components.

Opis:
Economic development of nations leads to a higher living comfort of the society. Rich societies want to move safely and independently and demand immediate availability of purchased goods or – in the case of Internet shopping – delivery in the shortest possible time. Such an approach facilitates a continuous growth in the number of road vehicles. At the current level of technology advancement, an increasing number of vehicles results in a growth of the consumption of fossil fuels, which entails increased exhaust emissions and that, in turn, has a negative impact on the health of the living organisms. Another negative consequence of an increased number of vehicles (increased road congestion) is the emission of noise. This problem is particularly significant in large agglomerations where people are surrounded by moving vehicles. This paper presents the extent of influence of the automotive industry on the natural environment and the extent of changes in vehicle design and organization of road infrastructure that were instituted to reduce the transport’s environmental burden. The further part of the paper presents a definition of the development of sustainable transport, its advantages and hurdles that we may encounter when modernizing a transport system. Subsequently in the paper, the measurements under actual vehicle operating conditions were described together with the possibilities of analysis of the research results and the advantages resulting from such an approach during the assessment of the impact of the automotive industry on the natural environment.

The article is a result of research work carried out under the project EMITRANSYS for shaping ecological transport system. The paper presents selected aspects of multi-variant distribution of traffic into transport network for defined scenarios of transport system development. Distribution of traffic on the network is made due to the global criterion function. Partial criteria for distribution of traffic are: external costs, marginal costs and average costs of the transport services expressed in monetary units and in emission units. An important aspect of the development of transport network is to include the external costs of transport activity to economical counting. The harmful components of exhaust gases, external costs for each mode of transport, list of selected external costs for each mode of transport [eurocents/vehicle-km], structure of communication between Warsaw - Gdansk, characteristics of connections in the communication network between Warsaw and Gdansk, distribution of passengers stream in relation Warsaw – Gdansk, the distribution of the passengers stream in relation Warsaw – Gdansk for the second scenario according to criterion of average and marginal costs are presented in the paper.
