Opis:
The article presents selected issues concerning the modelling of the supply chain in the evaluation of the efficiency of tasks realization. In the process of determination, efficiency of the functioning of the supply chain it is necessary to determine the components of both the effects and expenditures in quantitative terms. It is assumed that the effect resulting from action taken depends on the problem under consideration, for example, the result may be the amount of the profits, savings resulting from implemented solutions or measurable improvement of the quality system, expressed e.g. percentage. While the outlay incurred for the implementation of the action is, in general, the expense of implementing this action. The article pointed out that the assessment of the efficiency can be used to decide on the choice of a decision of the many variants of solutions to the problem. In this respect, important are indicators of the efficiency both the technical, economic, quality, and organizational. In the article were also presented possible approaches to improve the efficiency of the supply chain. In the problems of assessing efficiency of functioning of systems with a complex functional structure such as supply, chains increasingly are applicable algorithms based on the so-called heuristics. Hence, in the article briefly have been characterized also chosen heuristic algorithms – genetic algorithms.

Opis:
This article presents the issue of designating the number of docks at the transhipment terminals using genetic algorithm. Transhipment terminals refer to cross-docking terminals. The main factor that influences on the number of these docks is the stream of cargo flowing into the given terminal. In order to determine this flow of cargo the mathematical model of the distribution of this flow was developed. This model takes into account constraints like those that e.g. processing capacity at the transhipment terminal cannot be exceeded or demand of recipients must be met. The criterion function in this model determines the minimum cost of the flow of cargo between all objects in the transport network. To designate the optimal stream of cargo flowing into the transport network the genetic algorithm was developed. In this article, the stages of construction of this algorithm were presented. The structure processed by the algorithm, the process of crossover and mutation were described. In the article in order to solve the problem of designating the number of docks at the transhipment terminals the genetic algorithm was developed.

The quality of supply chain operation depends on quality of its particular elements, including warehouses. The paper presents an attempt to describe the quality of warehouse operation in terms of dependability. Authors discussed issues related to assessing warehouse operation, quality problems and solutions to increase the quality of work. The technical and organizational redundancy was proposed as a primary factor increasing dependability of warehous operation in supply chain and thereby improving the quality of services. Authors discussed dependability of supply chain and warehouses and have proposed an approach to determination of dependability of warehouse facility based on technological and organisational redundancy related to material flow pile-ups. The approach was founded on OTIFEF index as a base for dependability estimation. Construction of that index basing on probabilities of correct realization of different aspects of logistics service was proposed. An important element of the approach presented in the paper is proposal of technical and organisational indicators defining different aspects of redundancy in aspect of dependability. The example of redundancy assessment in function of technical and organisational methods of increasing warehouse efficiency has been provided.

Opis:
The paper presents an approach to the assessment of the location of facilities in the warehouse logistics network with the efficiency of its operations. Determination of efficiency of complex systems of this type should take into account wide range of issues. The system efficiency results on the one hand from the efficiency of its action and on the other hand from the ability to use available system elements to achieve the objectives. Efficiency is a main criterion to the evaluation of the activity both at the level of the whole system, as well as in its subsystems or components. Most often, it refers to the principle of rational management formulated in two variants: performance (maximization effect) and economical (minimizing effort). The article poses the thesis that based on studies of speed and reliability of execution of tasks it is possible to assess the potential locations of warehouse facilities in the studied logistics network. Were also presented factors affecting the efficiency of the functioning of individual cells of the logistics network. Was pointed to the technical, economic, organizational and reliability aspects affecting the efficiency and reliability of the logistics network in terms of both supply and distribution. It was also presented a modular block diagram of an assessment method for localizing logistics facilities in the logistics network.

Opis:
Introduction: It is shown in this paper, presented selected aspects of the impact that the distribution of products in a warehouse has on the picking of orders. This problem is particularly important for medium and large warehouses characterized by considerable rotation of goods. The aim of this study was to assess the impact of the method of classification of products that were used, on the efficiency of the order picking process. Method: For each classification method, two cases of picking products were considered, one including the impact of the fact that the products can be piled, and the other, that they cannot be piled. Simulation studies were preceded by a sensitivity analysis in order to determine the impact of the criteria on the effectiveness of each of the methods. Results: The best results were obtained after applying the product distribution in the warehouse on the basis of: COI Index or ABC analysis according to the number of units sold. It can be concluded that for large warehouses and for products with low susceptibility to stacking, the method based on COI Index proves to be the most effective. Conclusions: If susceptibility to stacking is irrelevant in the products picking process, for average-size and large-size warehouses it is important to distribute products on the basis of COI Index. This method allows obtaining better results than in the case of free storage places by an average of 28.72%. For products with low susceptibility to stacking, applying COI Index also proves to be the most effective.
Wstęp: W pracy pokazano wybrane aspekty wpływu, jaki ma rozlokowanie produktów w magazynie na proces poboru zamówień. Zagadnienie to jest szczególnie ważne w średnich i dużych magazynach, charakteryzujących się istotną rotacją wyrobów. Celem pracy jest ocenienie wpływu zastosowanej metody klasyfikacji produktu na efektywność procesu poboru zamówień. Metody: Dla każdej metody klasyfikacji wybrano dwie sytuacji poboru zamówienia, w jednej dopuszczalne jest sztaplowanie towarów, w drugiej nie jest. Następnie przeprowadzono symulacje i oceniono je przy pomocy analizy wrażliwości w celu określenie wpływu poszczególnych kryteriów na efektywność każdej z metod. Wyniki: Najlepsze rezultaty w rozlokowaniu produktu w magazynie otrzymano przy oparciu metody na współczynniku COI oraz analizy ABC w stosunku do ilości sprzedanych jednostek produktu. Można wnioskować, że w przypadku dużych magazynów oraz dla produktów o niskiej podatności do sztaplowania, najbardziej efektywną metodą była metoda oparta o współczynnik COI. Wnioski: Przy założeniu, że podatność na sztaplowanie nie jest istotna w procesie poboru towaru, w przypadku magazynów o średniej i dużej powierzchni, istotnym jest oparcie metody rozlokowania produktów na zastosowaniu współczynnika COI. Metoda ta pozwala na uzyskanie lepszych rezultatów średnio o 28, 72% aniżeli dla rozlokowania na zasadzie wolnego miejsca. W przypadku produktów słabo podatnych na sztaplowanie, również zastosowanie metody opartej na współczynnika COI jest bardziej efektywne.

Opis:
The paper presents a certain approach to solving the problem of warehouse locations based on the application of a genetic algorithm. The main objective is to indicate a location of warehouses from among those that already exist, which are most likely to assure the best value of the adopted criterion function, concurrently meeting recipients’ needs. A formal notation was presented of the mathematical model, allowing for the indispensable data, decisionrelated variables of limitations and the criterion function. The problem is to determine the location of warehouses taking into account minimising costs of transport and storage of forwarded cargo between determined facilities within the network. To allow solving the problem related to warehouse location within the logistics network of a manufacturing enterprise the use of a genetic algorithm was proposed. The structure of the algorithm was adapted to the mathematical model. A genetic algorithm was used to determine the volume of cargo stream flows between particular facilities in the network. To form a genetic algorithm it is advisable to define the chromosome structure, the adaptation function, cross-linking process and mutation. The location problem is solved in such a way that if for any day within the analysed period flows take place from a given warehouse or to a given warehouse, such a logistics facility should constitute an element of the target logistics network. If there are no such flows, no warehouse is necessary in the given location.

Opis:
The paper presents an approach to the logistics service for companies by warehouse facilities with different configurations in the logistics network. Through the warehouses it is possible to combine internal logistics functions such as ordering, unloading, product receptions, confectioning, order picking. The occurrence of warehouse facilities and suitable strategy also affects the volume of stocks, because they allow for combine reserves and compensates for fluctuations in demand. Optimal control of the amount of inventory reduces the demand for warehouse space and associates storage costs. The appropriate configuration of the warehouse facilities in the logistics network is therefore critical for effective logistics service of manufacturing companies. In such logistics network, individual subsystems are related to each other by different types of relation. From these interconnections result logistic tasks performed by company logistics system. Their implementation is caused both externally and internally, wherein the first considerations arise from the environment, the other from production. External logistic task is the boundary conditions for storage process in manufacturing company. The configuration of storage process determines the execution of internal logistics tasks for the company. The article also presents the logistics network configuration taking into account both direct and indirect services.

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:
Modelling of transport systems is a complex issue requiring taking into account many factors that allow for the mapping of the real system and thus allowing decision support. In the era of increasingly higher requirements for services, transport also faces the challenges of sustainable development. Therefore, it is necessary to conduct research both in the sphere of technical and organizational solutions aimed at limiting pollutant emissions. Mapping in the model the negative impact of transport on the environment allows for planning the implementation of the transport service taking into account the pro-ecological criterion. This is particularly important in urban areas where traffic and especially heavy goods vehicles are particularly onerous for inhabitants and require limiting transport work in the city area and the use of environmentally friendly rolling stock. The aim of the article is to present the considerations regarding the modelling of transport systems including pollutant emissions. The article introduces the problem of cargo distribution and a review of the models of estimation of pollution emission in the micro and macro scale was carried out. Next, a mathematical model was proposed which is a variant of the Vehicle Routing Problem of the so-called Green VRP. In the distribution model was used COPERT methodology for estimation of harmful substance emission. In article examples of calculations carried out on the example of the city of Warsaw for the organization of cargo distribution due to the CO emission criterion was presented. The article ended with a short synthesis of the work carried out.

Pursuant to Directive 2014/94 / EU of the European Parliament and of the Council of 22 October 2014 on the development of alternative fuels infrastructure, alternative fuels are fuels or energy sources that serve, at least partially, as a substitute for crude oil sources of energy in transport and which can potentially contribute to the decarbonisation of transport and the improvement of the environmental performance of the transport sector. In this aspect, the analysis of normative documents relevant to the use of alternative fuels in the area of transport was made. Reference was also made to the current state of the alternative fuels market as well as prospects for its development. The problems of environmental pollution by motor vehicles were presented and actions promoting electromobility in selected European countries were pointed out. The last part of the work presents the result of environmental research on the use of alternative fuels in Poland. The forecasts for electric vehicles are presented, taking into account three scenarios of their development and then, with the assumed boundary conditions, the values of pollutant emission limitations from the transport sector were estimated until 2025.
W pracy odniesiono się do zagadnienia ochrony środowiska w aspekcie rozwoju paliw alternatywnych. Zgodnie z Dyrektywą Parlamentu Europejskiego i Rady 2014/94/UE z dnia 22 października 2014 r. w sprawie rozwoju infrastruktury paliw alternatywnych, paliwa alternatywne to paliwa lub źródła energii, które służą, przynajmniej częściowo, jako substytut dla pochodzących z ropy naftowej źródeł energii w transporcie i które mogą potencjalnie przyczynić się do dekarbonizacji transportu i poprawy ekologiczności sektora transportu. W tym aspekcie dokonano analizy dokumentów normatywnych istotnych z punktu widzenia stosowania paliw alternatywnych w obszarze transportu. Odniesiono się również do obecnego stanu rynku paliw alternatywnych jak również przedstawiono perspektywy jej rozwoju. Przedstawiono problematykę zanieczyszczenia środowiska przez pojazdy samochodowe oraz wskazano na działania promujące elektromobilność w wybranych krajach europejskich. W ostatniej części pracy przedstawiono wynik badań środowiskowych w zakresie wykorzystania paliw alternatywnych w Polsce. Przedstawiono prognozy dla pojazdów elektrycznych z uwzględnieniem trzech scenariuszy ich rozwoju a następnie przy założonych warunkach brzegowych oszacowano wielkości ograniczeń emisji zanieczyszczeń z sektora transportu do roku 2025.

Opis:
W artykule przedstawiono nowe narzędzie optymalizacyjne wspierające zarządzanie łańcuchem dostaw w aspekcie wielokryterialnym. To narzędzie zostało wdrożone w systemie EPLOS (Europejski Portal Usług Logistycznych). System EPLOS to zintegrowany system informatyczny wspierający proces tworzenia sieci dostaw i dystrybucji w łańcuchach dostaw. Ten system składa się z wielu modułów, np. moduł optymalizacji odpowiedzialny za przetwarzanie danych, generowanie wyników, moduł danych wejściowych, moduł kalibracji parametrów algorytmu optymalizacyjnego. Głównym celem badań było opracowanie systemu do określania parametrów łańcucha dostaw, które wpływają na jego efektywność w procesie zarządzania przepływem towarów między poszczególnymi ogniwami łańcucha. Parametry te zostały uwzględnione w modelu matematycznym jako zmienne decyzyjne w celu ustalenia ich w procesie optymalizacji. W modelu matematycznym zdefiniowano dane wejściowe adekwatne do analizowanego problemu, przedstawiono główne ograniczenia związane z wyznaczaniem efektywnego sposobu zarządzania łańcuchem dostaw oraz opisano funkcje kryterium. Problem zarządzania przepływem towarów w łańcuchu dostaw został przedstawiony w ujęciu wielokryterialnym. Ocenę efektywności zarządzania łańcuchem dostaw przeprowadzono na podstawie globalnej funkcji kryterium składającej się z częściowych funkcji kryteriów opisanych w modelu matematycznym. Główne funkcje kryteriów na podstawie których wyznaczane jest końcowe rozwiązane to współczynnik wykorzystania wewnętrznych środków transportu, współczynnik wykorzystania zewnętrznych środków transportu, koszty pracy środków transportu wewnętrznego i personelu, całkowity koszt realizacji zadań transportowych, współczynnik wykorzystania czasu zaangażowania pojazdów, całkowity czas poświęcony na wykonanie zadań, czy liczba pojazdów. Punktem wyjścia do badania było założenie, że o skuteczności zarządzania łańcuchem decydują dwa problemy decyzyjne ważne dla menedżerów w procesie zarządzania łańcuchem dostaw, tj. problem przydziału pojazdów do zadań i problem lokalizacji obiektów logistycznych w łańcuchu dostaw. Aby rozwiązać badany problem, zaproponowano innowacyjne podejście w postaci opracowania algorytmu genetycznego, który został dostosowane do przedstawionego modelu matematycznego. W pracy szczegółowo opisano poszczególne kroki konstruowania algorytmu. Zaproponowana struktura przetwarzana przez algorytm jest strukturą macierzową, dzięki której wyznaczane są optymalne parametry łańcucha dostaw. Procesy krzyżowania i mutacji zostały opracowane adekwatnie do przyjętej struktury macierzowej. W procesie kalibracji algorytmu wyznaczono takie wartości parametrów algorytmu tj. prawdopodobieństwo krzyżowania czy mutacji, które generują optymalne rozwiązanie. Poprawność algorytmu genetycznego oraz efektywność zaproponowanego narzędzia wspomagającego proces zarządzania łańcuchem dostaw została potwierdzona w procesie jego weryfikacji.
The article presents a new optimization tool supporting supply chain management in the multi-criteria aspect. This tool was implemented in the EPLOS system (European Logistics Services Portal system). The EPLOS system is an integrated IT system supporting the process of creating a supply and distribution network in supply chains. This system consists of many modules e.g. optimization module which are responsible for data processing, generating results. The main objective of the research was to develop a system to determine the parameters of the supply chain, which affect its efficiency in the process of managing the goods flow between individual links in the chain. These parameters were taken into account in the mathematical model as decision variables in order to determine them in the optimization process. The assessment of supply chain management effectiveness was carried out on the basis of the global function of the criterion consisting of partial functions of the criteria described in the mathematical model. The starting point for the study was the assumption that the effectiveness of chain management is determined by two important decision-making problems that are important for managers in the supply chain management process, i.e. the problem of assigning vehicles to tasks and the problem of locating logistics facilities in the supply chain. In order to solve the problem, an innovative approach to the genetic algorithm was proposed, which was adapted to the developed mathematical model. The correctness of the genetic algorithm has been confirmed in the process of its verification.

Opis:
The paper discusses main decision problems analysed in the subject matter of servicing actors operating in the supply chains, i.e. the vehicle routing problem, vehicles-to-task assignment problem and the problem of entities’ localization in the supply chain. The input data used to describe supply chains is given as well as the basic constraints and the criterion functions used in the development of mathematical models describing the supply chains. Servicing actors in supply chains is the complex decision making problem. Operators in the supply chains are constrained by: production capacity of the suppliers, the demand of the customers in particular working days, storage capacities of warehouses, handling capacities of warehouses, suppliers’ and warehouses’ time windows and other. The efficiency of supply chain is described by cost of transport between operators, costs of passing cargoes through warehouses and delivery time to the recipient. The heuristic algorithms, like genetic and ant algorithms are detailed and used to identify issues related to the operation of actors operating in the supply chains are described. These algorithms are used for solving localization problems in supply chains, vehicle routing problems, and assignment problems. The complexity of presented issues (TSP is known as NP-hard problem) limits the use of precise algorithms and implies the need to use heuristic algorithms. It should be noted that solutions generated by these algorithms for complex decision instances are sub-optimal solutions, but nonetheless it is accepted from the practical point of view.

Opis:
This paper presents the problem of the assessment of the supply chains in the context of their effectiveness. In this paper the concepts of a supply chain and effectiveness were characterized. The supply chain is a structure of entities which are connected with each other by the use of material and financial flows and functional, structural, technological, economic and information dependencies. Entities such as: suppliers, final recipients, entrepreneurs, warehouse facilities, supply centers, logistics operators, carriers, etc. perform material flows from suppliers to recipients. The concept of efficiency, in general terms, refers to economic rationality and means the relationship between the achieved or expected effects and the expenditures incurred. Additionally, indicators of measuring the effectiveness of the supply chain were described. In order to assess the effectiveness of the supply chain the decision model was developed. Optimization is crucial in decision support systems. The development of an appropriate model for mapping the behavior of a real object or system and formulating an optimization task is a necessary activity in effective management. This is even more important if we want to be competitive. Along with the development of decision support systems, as well as the development of systems for data acquisition on the system functioning, which feed optimization models in ever more detailed form, complex decision models are created that take into account many optimization criteria and require a large amount of data. It allows, however, to ensure the sustainable development of the system and simultaneous implementation of its basic tasks. The main aim of this paper is to present the stages and assumptions of the model for assessing the effectiveness of the supply chain. The main data input, constraints of the model, the criteria functions were determined.

The paper presents a certain approach to fleet management in the company, taking into account the mobility of employees and the selection of vehicles for tasks. The main objective is to indicate the factors that significantly affect the proper selection of vehicles for the task, as well as concurrently meeting recipients' needs. The general model for fleet management was presented, taking into account not only the mobility of employees but also the method of obtaining funds for the replacement of greener cars. The current approach is based on the car purchase model in the form of credit, low-purchase leasing, and supervision over the use process and operating costs by the company's internal resources. The problem solved in the article concerns the analysis of entrusting fleet management to specialized Car Fleet Management (CFM) companies. It was pointed out that in this calculation model, CFM companies have to take into account many variables related to vehicle selection and mobility of employees in order to perform tasks. In this article, particular attention has been paid to the areas that CFM analyses when choosing a vehicle for a given company.

The paper presents issues related to design and organization of warehouse processes. Draws attention to problems of modelling logistics facilities and processes occurring in them. Paper also points out the essence of correct operation of warehouses and associated with this risks for supply chain. Warehouse processes have been properly defined and divided into smaller components, like: phases of process, activities, sets of procedures, procedures or working movements. Paper presents various possible configurations of warehouse processes, which were named as warehouse strategies. Warehouse process strategy is a part of warehousing. It determines the sequence of warehouse operations. These operations are related to internal transport, cargo form transformation and cargo buffering. In paper it is noted that the warehouse strategy depends on the several technical and organizational factors and is associated with a certain probability. This probability can be estimated based on data analysis concerning logistics processes in the specified warehouse facility. As shown in case study, appropriate selection of warehouse strategies determines possibility of fulfilling customer order in time and costs that are acceptable for him.

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.

The article presents selected aspects of shaping pro ecological transport system. Correct, socially responsible, economically reasonable and far-sighted allocation of resources is one of the basic tools of sustainable development shaping. In the case when this concept in a narrower sense refers to shaping the national transport system one can distinguish the general problem: how to invest financial resources in the development of the transport system and how to manage this system in order to one can say about it as "sustainable". The article presents the principles of creating scenario analyses, discusses the procedure and elements of an algorithm for the development of scenarios of the sustainable transport system. The procedure for conducting scenario consists of three stages of research. The analyses were conducted by the use of EMITRANSYS model. The EMITRANSYS model was developed in Visum. Its main elements are the network model, demand model, integrated database and a set of scenarios of an analysis of transport system development. The simulation model EMITRANSYS was developed under the PBS1 project "Shaping of the pro ecological transport system” financed by the National Centre of Science and Development. The project was realized within the consortium consisting of the Faculty of Transport of The Warsaw University of Technology and the Faculty of Machines and Transport of The Poznan University of Technology in the years 2012-2014.

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.
