1. "THE SUPPLIER SELECTION PROCESS IN REGIONAL TERMS – CASE STUDY ANALYSIS"
Barbara Galińska, Renata Pisarek-Bartoszewska

The article presents a supplier selection procedure, which is one of the key elements of the whole procurement process, carried out in each business entity. Particular attention was paid to the regional aspect of the issue. It has also been presumed that in the case study, only local suppliers will be taken into account. Such assumptions (including close distance between potential supplier and a company) foster e.g. reduction of costs and delivery time, enhance all supply chain and enable implementation of modern management concepts. In times of strong competition, all these aspects have become particularly important. In the phase of computational experiments, which aimed at ranking and selection of the most desired supplier in the case study, multiple criteria ranking methods - Electre III/IV and Promethee II have been applied.

3. "INFORMATION FLOW IN THE SECURITY MANAGEMENT SYSTEM"
Marzena Graboń-Chałupczak, Wojciech Chałupczak

Implementation of security objectives is conditioned by fast access to reliable and up-to-date information about processes occurring within the Safety Management Systems. The amount of information and the speed of changes taking place in the environment makes it necessary to introduce a system of information management and channels of their flow not only within the organization, but also in communication with third parties. Proper management of information resources increases the efficiency and effectiveness of SMS functioning. The article presents the possibility of a formalized description of the flow of external and internal information in a well-functioning Railway Operator Safety Management System.

5. "DESIGNING A MORE EFFECTIVE SUPPLY CHAIN"
Tony Wild

Supply chain can be considered as a series of linked inventories. This paper considers the impact of inventory on the economics of the businesses and the whole chain and discusses causes of inefficiency. In most supply chains the goods are inactive for the majority of the time, and this leads to longer term and therefore less accurate forecasting. The result is typically excess inventory, shortages, and inflexibility. By analysing the wasted time and costs in the supply chain, a clearer view of the whole process can be created. Total supply time can be considered as three components, namely value added time, non-value added process time, and waste time. This basic approach shows where improvements should be focussed. Using this time-based measurement enables more relevant comparison between supply chains than the normal supply chain efficiency ratio.

6. "VIRTUAL WORK IN THE SUPPLY CHAIN IN E-ECONOMY"
Sabina Wyrwich-Płotka

The problem that is taken under consideration in the following article concerns the implementation, use and effectiveness of virtual work in the supply chain in e-economy. Any solution concerning employee mobility or the use of mobile technology are due to growing market competition and constant search for new solutions that may enable the companies in the supply chain to be more efficient than their competition. In the supply chain the e-business creates for the companies new challenges they have to face. One of the possibilities to improve your business in the supply chain is to use virtual work. The new challenge facing the e-economy needs to be met. The aim of the article is to refer the virtual work that is used by selected links in the supply chain to meet the e-economy requirements, identify the key factors that characterize e-economy and refer them to the possibilities and benefits of using virtual work in the supply chain.

8. "SUSTAINABLE DEVELOPMENT OF TRANSPORT ENTERPRISES IN POLAND – STATISTICAL ASSESSMENT "
Anna Misztal

The main purpose of this paper is to show a statistical evaluation of the sustainable development issues at the transport enterprises level. Initial considerations are devoted to the discussion of theoretical issues related to sustainable development businesses. The main part of the article is devoted to the statistical analysis of the sustainable development of Polish transport companies. The results of the study made it possible to assess that the sustainable development of transport companies in 2009-2015 takes place. This development is more rapid compared to the average development of the entire enterprise sector. The average level of the indicator of sustainable development of transport enterprises in the whole analysed period it amounted to 0.89. At the same time, it should be noted that economic development is accompanied by improvement of conditions and quality of work and reduction of negative impact on natural resources.

9. "THE EVALUATION OF THE SELECTED RISK TYPES IN EXTERNAL TRANSPORT WITH THE USE OF THE MATRIX METHOD"
Mariusz Niekurzak, Ewa Kubińska-Jabcoń

Risk is a common phenomenon in daily life of natural and legal persons. It concerns all branches of the economy and relates to making decisions concerning the unknown future. There are various types of risk related to business operations and the majority of business entities take effort to protect themselves against its adverse effects. The development of the field of risk management allows for partial or total risk elimination. Road transport is exposed to various types of risk which may lead to usually considerable damage and losses. This publication is aimed at presenting selected groups of risk factors occurring in the logistics process and at determining their influence on enterprise functioning. It is also supposed to emphasize the significant role of risk analysis in the transportation business.

11. "ENVIRONMENTALLY SUSTAINABLE TRANSPORT PLANNING IN THE FIRST AND LAST MILE SECTION OF THE SUPPLY CHAIN "
Grzegorz Sierpiński, Marcin Staniek

Background: The article provides a discussion on freight transport planning. The existing solutions applied in this sphere have been compared with the environment-related needs. The concept which has been proposed involves a dedicated travel planner that takes some additional non-standard criteria into consideration. At the same time, the authors have highlighted the necessity to expand the algorithms being applied, and to address the comprehensive nature of the problem. However, it is the first and last mile section of supply chains on which the article focuses. The planner described in the paper is being developed as a part of an integrated platform implemented under the international S-mile project. Research methodology: The solutions proposed for transport planning purposes include application of ICT. A review of the available solutions has made it possible to indicate one of the planners currently in use as the foundation upon which a more advanced freight transport planning tool dedicated to the first/last mile section can be built. The planner requires application of several optimisation algorithms, including those which consider route parameters, the selection of fleet vehicles available for the given task, cargo distribution over the vehicle etc. The article defines both primary and secondary criteria that such a planner should take into account, including the environmental ones. What the authors have also highlighted is the possibility to make use of open data sources. The approach they have proposed makes it possible to raise the level of environmental awareness at the first and the last mile management stage, and since multiple transport aspects have been addressed, it also increases planning efficiency. Goals: The purpose of the article has been to discuss an eco-friendly solution which may limit the negative environmental impact of transport. Conclusions: The solution described in the paper may change the manner in which freight transport is managed in cities. Taking environmental criteria into consideration makes it possible to reduce the negative environmental impact of transport. Planning of freight transport requires that far more criteria should be taken into account compared to route planning for the travelling population. A comprehensive fleet management platform featuring a planning module combined with other modules of the S-mileSys system being currently developed is also aimed at integration of large freight companies with the carriers that service first and last miles.

14. "THE ANALYSIS OF THE STABILITY OF THE COMMUNICATION SUPPORT STABILIZED BY GABION WALL WITH VARIABLE CONFIGURATION "
Zenon Zamiar, Andrzej Surowiecki, Piotr Saska, Adam Balawejder

The subject of the article concerns the stabilization of communication earthworks using the so-called lightweight retaining structures. The stability of the embankment with the embankment built with the gabion wall is analysed, assuming a uniformly distributed load on the crown and a case of unilateral water pressure in the event of a flood. Final results of stability calculations made with the Fellenius and Bishop method in the form of slip surface with the smallest value of the coefficient were presented. Then, assuming the case of damming up of flood water, discretization of the filtration area, velocity distribution and hydrodynamic grating and slip surfaces were developed. The variable parameter is the wall configuration.
