Analysis of the aviation safety management system by fractal and statistical tools
Get PDFoai:ojs.logistics-and-transport.eu:article/713World civil aviation is an open-source system that is affected by a large number of related and non-related factors. Aviation safety is one of the prioritized directions in the industry. Its managerial decision-making is primarily based on a versatile analysis of security data in which the choice of the appropriate mathematical apparatus is fundamental. This article suggests applying fractal-statistical analysis to evaluate the aviation safety management system in terms of determining the random distribution of quantitative dynamics of aircraft crashes with lethal consequences in the period from 1946 to 2017. This allows us to verify the adequacy of probabilistic approaches appliance in analyzing the dynamics of aviation disasters. The results of research carried out on the basis of the Hurst exponent have allowed us to conclude that the dynamics of aviation disasters is characterized by the effect of "spatial memory". In other words, these are "hidden laws" which further investigation can become an effective tool for the development of proactive methods in managing aviation safety
MODELLING QUALITY ASSESSMENT OF THE SUPPLY CHAINS
Get PDFThe article presents how to use methods and tools in the area of quality engineering to assess the supply chain, having the example of the food industry. It outlines the regulatory requirements and standardization documents for the transport of dairy products. Using a questionnaire conducted it selects criteria that were directly used to assess the quality of the supply chain (network). Then, using the Pareto-Lorenz diagram the most important criteria were selected, which were also used in the study
The Impact of Brexit on the Transport Industry
Get PDFOn 29 March 2017, the United Kingdom of Great Britain and Northern Ireland (UK) announced its intention to leave the EU and all its institutions, including the European Court of Justice (ECJ), European Civil Aviation Area (ECAA), European Agency for Railways (ERA), the European Aviation Safety Area (EASA), etc. – also the European Atomic Energy Community.Under Article 50 of the 2007 Treaty of Lisbon, there is a two-year time period allowed to make a withdrawal agreement. Thus on 30 March 2019, the UK will no longer be an EU member, unless the European Council unanimously votes to extend this period.The Withdrawal Agreement is then subject to ratification by the European Parliament and also (by qualified majority vote) the European Council (i.e. 16 countries representing more than 65% of the EU population).
Information flow in the Security Management System
Get PDFImplementation 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. Analogous maps can be identified for infrastructure managers, defining key elements of its functioning
Logistics in Shaping Competitive Edge of Enterprises
No full textLogistics as a factor in shaping the competitiveness of enterprises has already been discussed in numerous publications. Still, however, being a problem with very broad substantive and methodological horizons, according to the authors, it allows for the analysis and formulation of theses that have not yet been scientifically explained.The theoretical foundations of logistics in its dimension of the competitiveness factor can be traced at various levels of delimitation of economic sciences: micro, meso or global. The starting point for such focused considerations is the current of classical competition theory. The theory of imperfect competition should be the basis for consideration in this direction. The methodological assumptions of the new industrial economy (industry economics) are extremely interesting and inspiring in the field of logistics research as a competitive factor. The purpose of this article is to present selected trends in economic research in the development of logistics theory and to systematize the theory underlying the considerations regarding the competitiveness of logistics
Future hubs on the background of Physical Interment implementation
No full textThe Physical Internet (PI) is the matter of time. There is not any other concept of future logistics so simple and so complicated at the same time. Simple, because we all do it now with data. Complicated, because goods are not so elastic like figures. The range of required transformation of hubs technology before implementing of Physical Internet is massive. Some technologies require only modification, other inventions, not possible nowadays. But it can be assumed, that from technological point of view it will be possible to improve the hubs to required level till 2050. There is still unsolved matter of financing and organization

Designation of a paid parking zone in Łódź
Get PDFThis article has two aims: cognitive and methodological. The first one focuses ondelineating city areas (of Łódź in this case), in relation to whicha conscious parking policy should be implemented, including differentiation of the base parking feeand dynamics of parking cost increment in time. The methodological aim, in turn, consists in elaborating a research algorithmbased exclusively on the geographical information system,which is based on generallyavailable vector data,together with data obtainedfrom intelligenttransport systems. For their realization of the authors of this article elaborated their own methodology. It consists of five stages. The basic research unit isthe surveying district. The area on the basis of which the research was made is the Łódź urban zone defined in the Strategy of Spatial Developmentfor Łódź (2012). Each research stage corresponds to defining the powerofimpact of the variablewhich, as an research overview shows, affectsthe parking policy. Since the research is conducted on the basisdifferent variablesat individual stagesand finally thecoefficient assumes the form of five elements, it is necessary to standardize partial results. The article usesa procedure based on thequotient of the difference between the calculated valueand the averagefor the wholegroupdivided by standard deviation. The results of the conducted researchin the cognitive scopeshow that problems connected with parking organizationdo not concern only the very city centre (mostly the district of Śródmieście). Particular attention should be drawn to areasnext to the city’s main transport arteries which golatitudinally (for instance, Piłsudski avenue) ormeridionally (e.g. Kościuszki street, Zachodnia street)
The Use of the Queueing Theory for the Analysis of Transport Processes
No full textThis article focuses on the application of queueing theory for the analysis of transport processes with regard to rail traffic. Selected aspects of queueing theory application for the analysis and rail traffic flow assessment were presented. A literature review regarding process modelling in rail transport using mass service theory models was performed. In order to study rail traffic flow, the application Java Modelling Tools- JSIMgraph was used. The train movement process was analysed with regard to traffic flow. The study was conducted on the basis of selected stretches of railway lines, numbers 2 (central long-distance in Warsaw) and 448 (central suburban in Warsaw).
INTEGRATION OF MANAGEMENT SYSTEMS IN RAILWAY TRANSPORT
Get PDFThe mandatory management systems implemented since 2008 in rail transport resulting from legal requirements [1-8], very often (especially in the first years of implementing the requirements) functioned independently of the optional procedural approach - ISO standard [9-10]. Currently, integration of requirements in both the mandatory and voluntary areas has become common practice. Legal requirements and recommendations do not define or recommend any specific form of extending the existing management systems. Regulation EC 402/2013 in Article 3 point 7 [8] defines only the obligation of interaction between systems (interfaces mean all interaction points during the system or subsystem life cycle). The publication describes the relationship between the requirements in the field of management systems currently used in the railway system resulting from legal requirements (Safety Management System - SMS) and voluntary implementations (Quality Management and Environmental Management System)
