1. "POLISH RAILWAY SAFETY PERFORMANCE IN 2016"
Leszek Mindur, Marek Sitarz, Rafał Wachnik

In comparison, railways are the safest mode of land transport, not only regarding pure safety performance indicators but also considering external costs to society and to a member state. As for Polish railways, the year 2016 was the safest since 2008 even despite the growth of the railway market. There are still elements that need to be taken care of, such as continuous improvement of safety culture so that there can be a consistency in safety statistics, and improvement of total safety performance. The other key aspect is the analysis of human factor with the involvement of professionals in the area of human performance since it seems that current activities are insufficient. Authors would like to summarise this short article regarding railway safety performance by saying that undoubtedly, railways are constantly the mass transport mode to choose regarding the safety of travel.

3. "SUSTAINABILITY OF LOGISTICS AND SUPPLY CHAIN OPERATIONS THROUGH CORPORATE SOCIAL RESPONSIBILITY INITIATIVES"
Benjamin Bvepfepfe

So much pressure abounds for supply chains to deliver goods and services in the right quantity, quality, to the right place and at the right time and least cost possible. It is an acceptable fact that supply chain operations, local or global, face numerous unforeseen challenges that expose them to ineffective and inefficient performance. It is evident that organizations that manage environmental, social and economic risks are better positioned to deliver sustainable supply chain operations. The next generation of supply chain management should not be comfortable with the old adage of out-of-sight out-of-mind behaviour as this presents an unacceptable reputational risk level to the sustainability of logistics business operations.

4. "LEAN MANAGEMENT CONCEPT IN THE ENVIRONMENT OF CLUSTER ENTERPRISES"
Irena Pawłyszyn

Increasing regional and local policy, aimed at boosting the competitiveness of regions and provinces is now becoming a common practice in the globalized economy. Therefore, in this article an important segment of the market is analyzed, which is regarded not only as a tool for enhancing the competitiveness of individual companies, but also of entire economies, namely - industrial clusters. The main research problem of this article was to determine if cluster enterprises are familiar with the Lean Management concept and if they practice it. The aim of the studies included in the paper was to identify the scope of usage of the Lean Management concept among cluster enterprises. At the same time within the study it was identified whether between businesses practicing the above-mentioned concept, there is any information exchange – any diffusion of knowledge.

5. "A PROGNOSTIC MODEL OF DIESEL FUEL CONSUMPTION FOR RAILBUSES"
Izabela Dziaduch

In this article, the model for prediction of diesel fuel consumption by railbuses is presented. In order to create the model, the results of measurements of the average fuel consumption of eight dual mode railbuses of type X (manufactured by the same producer) are used. The usefulness of the indicators method in additive and multiplicative version is assessed. For both models, the percentage share of the trend, seasonality, and irregular (random) components are analysed and the results for the multiplicative version are given.

6. "OPERATIONAL RESEARCH OF WEAR OF RAILWAY BUFFERS HEADS COVERED WITH ALUMINUM BRONZE"
Wojciech Gamon

In recent years in Europe and in Poland a discernible trend of significant increase safety in rail transport can be observed. Safety improvement is realized at many levels and in many aspects (organizational, systematic, technical etc.). Implementation of Safety and Maintenance Management Systems are an example of activities seeking to systematically increase safety in rail in Europe. Similarly, on the part of technical solutions, there are discernible activities which are aimed at improving the safety level. There offer new construction solutions, new control systems or new communication technologies which are designed to increase reliability and safety of this mode of transport. For innovations introduced in vehicles, almost only improving safety in the field of implementing enhancements in construction of running gear systems of vehicle used to be thought about. However, it is worth remembering that not only the bogie, wheel set or wheels are responsible for the proper cooperation of the vehicle with the track and its safe running. Elements that have not been yet subjected to deeper analyzes are railway buffers whose proper maintenance and cooperation is a guarantee of correct vehicle dynamics, especially when passing through rail curves. This article presents the results of operational research of railway buffers whose heads were covered with an aluminium bronze layer. This solution has helped to increase the durability of their co-operating surfaces, and has allowed the resignation of the now-proposed solution, which consists in periodically covering buffers heads with the grease which has a lot of defects.

7. "PILOT STUDY OVER SECONDARY TASK COGNITIVE WORKLOAD INDUCED ON DRIVERS IN AS 1200-6 SIMULATOR"
Mikołaj Kruszewski, Michał Niezgoda, Tomasz Kamiński, Arkadiusz Matysiak, Mirosław Nader

Modern cars are more and more frequently equipped not only with the driver assisting systems, but also with multimedia devices allowing to track the information, use the Internet or send and receive e-mails. This type of activity can cause dangerous situations by inducing various forms of distraction to the driver. In order to identify the effects caused by performing additional tasks while driving, two types of secondary tasks were proposed. The following article presents the results of a pilot study that uses two additional tasks to induce the driver with cognitive load not related to driving. At the same time, in the course of the experiment, both the driving performance and the quality of performing additional tasks were observed. The article describes selected results of the conducted study.

8. "DATA MINING APPLICATION IN AIR TRANSPORTATION – A CASE OF TURKISH AIRLINES"
Renata Pisarek, Musab Talha Akpinar, Abdulkadir Hızıroglu

The paper presents an exemplification of data mining techniques in aviation industry on the basis of Turkish Airlines. The purpose of the paper is to present application of data mining on the selected operational data, concerning international flight passenger baggage data, in year 2015. The differences in passenger and flight profiles have been examined. Firstly, two-steps approach allowed defining the number of clusters. Secondly, K-means clustering were applied to divide data into a certain number of clusters representing the different areas of consumption. Results can contribute to higher efficiency in decision making regarding destination offer and fleet management.

11. "FACTOR ANALYSIS AS A MEANS OF FILTERING RAMS INDICATORS FOR RAILWAY VEHICLES"
Marek Sitarz, Katarzyna Chruzik, Marzena Graboń-Chałupczak

European Commission Regulation (EU) No. 445/2011 regarding the system of certification for entities in charge of maintenance (ECM) of freight wagons requires such entities to supervise the condition of wagons, without specifying the methods of supervision to be used. Each ECM should establish a Maintenance Management System (MMS), which will include the obligation to monitor the fleet of freight wagons. Monitoring railway vehicle maintenance operations should include tracking all significant technical and operational indicators. The key question is which indicators are the have the greatest impact on safety. This paper discusses some issues related to the monitoring of maintenance operations for railway vehicles. It also looks at dedicated solutions for entities in charge of the maintenance for freight wagons based on PN-EN 50126:2002 standard and RAMS indicators (Reliability, Availability, Maintainability and Safety). This paper describes factor analysis of the proposed indicators as a means of selecting those that have a decisive impact on the correctness of the process for monitoring vehicles. This paper shows an example of the implementation of the requirements of the European Commission Regulation 445/2011 [3] regarding the monitoring of the state of railway vehicles and the possibility of using the information so gained as part of a process of continuous improvement. Reducing the number of indicators will reduce the amount of data needed to calculate all the RAMS indicators, without compromising the benefits of the rail vehicle monitoring system.
