1. "THE VARIETY OF SUPPLY CHAIN DESIGN: FROM A STANDARD TYPOLOGY TO A RELATIONAL PRAGMATISM"
Thierry Houé, Renato Guimaraes

Supply chain management is at the heart of business strategy. The types of goods delivered are extremely varied and the way to deliver to the final consumer is more and more complex. Moreover, the relations between players within the supply chain take multiple shapes and have inevitably an impact on its design. This arena of complexity leads companies to use diverse kinds of relational approaches. But the relational view is itself a large field of study and a recent trend in supply chain management. It can be focuses on joint planning, coordination, and process integration between suppliers, customers, and other partners in a supply chain. Its benefits include cost reductions, an increasing reliability and a strong responsiveness to market needs. In addition, managing a sustainable supply chain involves today additional parameters like CO2 emissions reduction, energy consumption decrease, eradication of traffic congestion problems and the need for a better traceability. Besides, recent progresses in inter-companies’ communication technologies, along with a growing use of strategic partnering, has resulted in a large variety of alternative information systems approaches for supporting a collaborative supply chain management. Helped by theories and based on empirical data from specific cases companies, this exploratory and conceptual research shows the relative influence of various specific environments on the coordination of logistics flows, with a focus on relationships between different players. This work analyzes diverse types of supply chains and gives a framework confronted with some examples showing how different players create new models of logistics organization in particular situations.

3. "THEORETICAL APPROACHES FOR SAFETY LEVELS MEASUREMENTS – SEQUENTIAL PROBABILITY RATIO TEST (SPRT)"
Volodymyr Kharchenko, Marcin Pawęska, Dmytro Bugayko, Anna Antonova, Maria Grigorak

The principles of civil aviation safety are considered. At present time, aviation is an ultra-safe system, (i.e. a system that experiences less than one catastrophic safety breakdown every one million production cycles). But, unfortunately, we can never state that aviation activities will be absolutely safe. In current conditions the increase of the civil aviation safety level is one of the principal objectives of the world air transport development. The paper pays special attention to the civil aviation threats and risks in the context of globalization processes. The investigation deals with problems of global implementation of Annex 19 to the Convention of the International Civil Aviation. Present research paper discusses new theoretical approaches to searching for methods to assess the “safety space” of civil aviation activity. Special attention is paid to an effective test, proposed by A. Wald.

4. "THE ANALYSIS OF THE CONSUMER SATISFACTION WITH THE QUALITY OF LOGISTICS SERVICES IN THE DPD COMPANY"
Kamil Roman, Damian Sawczuk

Customer service is one of the leading elements of modern logistics. The issues connected with the quality of services as well as to the level of customer service are the subject of interest of many researchers. Based on the literature of the subject, it can be safely stated that the most of the available papers focus on the theoretical aspect of this matter. Therefore, in the following work one can see an attempt of presenting the process of implementing logistic customer service based on one of the leading courier companies in Poland. Dynamic Parcel Distribution (hereinafter referred to as DPD) is a company that owns nearly 30% of shares in the Polish courier market. The significant position of the national leader in the courier service business obliges the company to conduct the responsible and efficient customer service that is adjusted to the demands of the buyers. The purpose of this study was to investigate how logistic customer service improves the relationship between company and its customers. The evaluation of research findings will result in proposing solutions that will aim to improve the processes connected with the customer service in the DPD Company.

6. "HISTORIC RAILWAY SPANS MODERNIZATION WITH THE USE OF MODERN SLAB TRACK SURFACES, ON THE EXAMPLE OF THE WROCLAW GŁÓWNY – WROCLAW MAIN RAILWAY STATION RECONSTRUCTION"
Grzegorz Antoniszyn

Modernization or revitalization of a railway line involves the necessity of reconstruction or renovation of practically all the engineering objects and constructions on its premises. While, in the case of objects, not protected by the Historic Preservation Maintenance of City-Owned Buildings, the situation is relatively easy, in the case of historical buildings, the scope of possible construction works can be significantly reduced. On the example of the modernization of the Wroclaw Główny railway station track system, the use of modern slab track is presented, whose aim is to obtain the required performance parameters of the engineering structures (old boreholes) located in its area. The non-skid surfaces used are ERS - rails in the cover and block rails of the EBS type. The use of pavement-free pavements allowed the historic bays to be preserved. Their main girders are made of riveted baffles, without interfering with their historical material. The presented solutions can also be used for the modernization of different types of engineering objects and construction, not necessarily recorded in the register or records of historical monuments - for example, in riveted constructions of those of or unique shape, located on lower category railway lines. It gives opportunity to preserve and continue to use old objects, exposing their beauty and technology, currently not used (for example riveting).

8. "SIMULATION METHODS APPLICATION FOR LPG DELIVERIES PLANNING AND SCHEDULING TO THE NETWORK OF STATIONS UNDER DEMAND UNCERTAINTY"
Marek Karkuła, Jacek Kaleta

In our paper we considered the problem of demand uncertainty and its influence on planning and scheduling of LPG deliveries. The experience of specialized transportation company in charge of LPG deliveries for the domestic supplier network under VMI approach was analyzed. High variability of distribution parameters and frequent orders modifications were observed while small stations tanks capacities comparing to high daily LPG sales volumes were considered. The combined use of simulation and optimization methods was proposed for the case of LPG distribution to the petrol stations network. The demand uncertainty at customers' stations was considered. Simulation models were assumed to be efficient for dynamic and robust delivery plans of LPG distribution. The results of computational experiments were presented for different values of coefficient of variation.

9. "IDENTIFICATION OF THE MOST IMPORTANT SUSTAINABILITY TOPICS IN SEAPORTS"
Natalia Wagner

Preparing a sustainability report becomes more and more popular among a wide range of branches including shipping and seaports. For majority of Polish ports preparing a formal CSR strategy is a new challenge. The aim of this article was to compare the way that selected European seaports chose to report and identify the most important topics of their sustainable activity. In order to answer the research questions the multi-case study of selected European ports was prepared. The strategy and identified topics at seaports that have prepared sustainability reports can be used in benchmarking process. Such a comparison can help Polish seaports avoid mistakes in preparing such reports by themselves in the future. The analysis showed that the most important sustainability topics are connected with employment and air emission. There were also themes specific for seaports activity like maintaining the water depths. Involvement the port stakeholders in prioritization process made the topics order suited all parties concerned in port operations.
