Opis:
We współczesnych systemach transportowych występują elementy o bardzo dużych wskaźnikach niezawodności. W pracy zaproponowano dla takich sytuacji zastosowanie ogólnej teorii procesów stochastycznych do analizy i modelowania obiektów wielostanowych.
In contemporary transportation systems certain elements have a very high reliability factor. In such situations the general theory of stochastic processes can be used in examining and modeling multistate objects.

A purpose of the article is discussing the method of technical systems reliability modelling. The most important methods used for constructing realist models of the physical world, i.e. the method of the experimental modelling and the method of the probabilistic modelling, were presented. The particular attention was focussed on the method of the probabilistic modelling allowing for taking into account uncertainty in functioning of systems. An example of using the proposed method to the modelling of the reliability of the air-traffic-control-system was quoted.

Udział matematyków w realizacji projektów gospodarczych w Polsce, w których realizacji matematycy metody matematyczne odegrały istotną rolę pojawiał się sporadycznie w przeszłości. Zwykle sprawdzone i znane z opracowań opublikowanych metody są adaptowane do rozwiązywania pokrewnych problemów. Przedmiotem prezentacji będzie współpraca jaką nawiązali matematycy i inżynierowie we Wrocławiu w drugiej połowie XX wieku przy analizie efektywności systemów inżynieryjnych stosowanych w górnictwie. Efekty tej współpracy spowodowały wprowadzenie metod projektowania w technice wcześniej inżynierom nieznanych. Otworzyły też tematy badawcze w teorii procesów stochastycznych i teorii grafów. Interesujące są też społeczne aspekty tej współpracy.
The participation of mathematicians in the implementation of economic projects in Poland, in which mathematics-based methods played an important role, appeared sporadically in the past. Usually verified and known from the publications of published methods are adapted to solve related problems. The subject of the presentation will be the cooperation established by mathematicians and engineers in Wrocław in the second half of the twentieth century in the analysis of the effectiveness of engineering systems used in mining. The effects of this cooperation resulted in the introduction of methods of engineering design to previously unknown engineers. They also opened research topics in the theory of stochastic processes and graph theory. The social aspects of this cooperation are also interesting

Opis:
In the study, the authors focused on determination of reliability indicators of the transport systems, which currently constitute the Polish Armed Forces’ equipment. The methods of research of car fleets composed of distinct types of vehicles are presented. The algorithms of reliability indicators’ determination addressed in the study can serve to analyze other set of transportation means used in rescue, seasonal transport and specialized transportation assignments, as well as to determine the security level of any mission conducted. The appearance of information technology allowed transferring the paper-based registration system of operational occurrences into an integrated information system. It enables to follow the history of transportation fleets including single pieces of the equipment. The knowledge of reliability of particular types of the vehicles allows for proper planning of missions within the framework of possessed transport assets capacity. The study presents the method of achieving the intended objective to increase the effectiveness of management of motor vehicles fleet used intermittently. The algorithm for the selection of a vehicle or a group of vehicles for execution of tasks, developed on the basis of analytical procedures, envisages the assignment of mobile assets, complication and complexity of their structures, the level of modernity, operational history and branch regulations. Determined reliability indicators for particular groups of vehicles can be implemented into the Multilevel Information System.

The models of the non-renewal reliability systems with dependent times to failure of components are presented. The dependence arises from some common environmental stresses and shocks. It is assumed that the failure occurs only because of two independent sources common for two neighbour components. The reliability function of series and parallel systems with components depending on common sources are computed. The reliability functions of the systems with dependent and independent life lengths of components are compared.

Opis:
Transport telematics systems integrate information technology with telecommunications for their use in various transport systems. Thanks to the use of advanced technical solutions and modern telecommunications and IT systems, it is possible to implement additional innovative services. They can be used to rationalize the process of using and maintaining means of transport. Modern vehicles are equipped with telematic on-board systems. Such solutions combine various electronic devices used in the vehicle. For this purpose, bus solutions are used, thanks to which it is possible to control individual systems and devices. It is also possible to use the transmitted data to detect negative exploitation phenomena during vehicle use (e.g. glazing phenomenon, work in the upper engine rev range with too low coolant temperature, intensive work compressor of the high air pressure system being a symptom of inability of pneumatic systems). This is possible because the data being sent has a specific information resource. Thanks to this, to can be concluded about the loss of the exploitation potential of the vehicle. This approach will be used to rationalize the technical service of the vehicle fleet, with regard to profiling. Using exploitation data, received via a telematic interface from vehicles, it is possible to profile the rolling stock. It consists in distinguishing individual sets of vehicles due to certain reliability and exploitation properties. This approach allows for the specification of the rolling stock exploitation, giving the opportunity to rationalize the use and exploitation. The publication presents the author’s graph of the exploitation process taking into account the profiling of the vehicle fleet. The application of the presented approach will contribute to the improvement of the value of certain vehicle reliability and exploitation indicators.

Opis:
The safety of transport facilities depends not only on effectiveness of the applied individual safety systems but also on their power supply systems’ proper operation (also including electromagnetic interferences). Therefore, in this paper, the authors analysed the power supply selection for the electronic safety systems applied in transport, taking into account the reliability and exploitation requirements included in the regulations and standards on these systems. The appropriate electricity supply to electric safety systems is the basis of their proper functioning. It means that the power supply, with required parameters for a given device, should be connected to individual electric receivers of electric safety systems. However, only supplying electricity to the device is not equivalent to provision of its operation continuity and the appropriate level of values of the reliability and exploitation indices. Therefore, emergency power supply systems should be used. The authors developed an algorithm of the power supply selection for electronic safety systems, including the categories of power and hazards occurring in the facility. In further considerations, it is planned to carry out further analyses taking into account other types of power supply systems, and the development of a computer programme, which constitutes an exemplification of the obtained deliberations.

Opis:
This paper presents a method which makes it possible to determine reliability characteristics of navigational positioning systems, relevant to an assumed value of permissible error in position fixing. The method allows to calculate : availability, reliability as well as operation continuity of position fixing system for an assumed, determined on the basis of formal requirements - both worldwide and national, position-fixing accuracy. The proposed mathematical model allows to satisfy, by any navigational positioning system, not only requirements as to position-fixing accuracy of a given navigational application ( for air, sea or land traffic ) but also the remaining characteristics associated with technical serviceability of a system. Essence of the method in question consists in the working-out of recorded empirical position-fixing data as well as the making use of multi-state Markov processes ( appropriate to a maximum error value permissible for various navigational applications ) as a result of which reliability characteristics based on real data would be determined. About usefulness of a given navigational positioning system for its possible application would decide a vector of variables (both dealing with position and reliability) which satisfies / or does not satisfy/ formal navigational requirements for a given application.
