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.

Opis:: 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.

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.

Opis:: 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.

Opis:: 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.

Opis:: The paper is a result of research work carried out under the project EMITRANSYS for shaping ecological transport system. The paper presents selected aspects of emission and concentration of harmful compounds of exhaust gases generated by road transport. It also presents the share of harmful compounds emitted by road transport in comparison with the emission from other sectors of economy. Transport policy should encourage the usage of energyefficient and less environmentally damaging modes of transport and their efficient use. The paper analyses the emissions of selected pollutants and their estimated contribution to the total emissions of road transport. It also presents selected aspects of the identification of areas with the highest emissions of harmful compounds in Poland against the European Union. This analysis provides a basis to identify the instruments to prevent and reduce pollution arising from transport activities. In particular, variable emission of selected components of fumes according to the velocity of passenger vehicle. the measured values for NO2 concentration in the UE countries in 2011, the measured values for CO concentration in UE countries in 2011, the measured values for PM10 concentration in UE countries in 2011, the measured values for PM2.5 concentration in UE countries in 2011 are presented in the paper.
