Opis:: With the worldwide competition so strong, it is essential for motor vehicles, regarding to power transmission, to have high reliability. The reliability design is one of the ways to reach this objective. The stage of design is the most important one in the life cycle of a power transmission. Reliability design, within the designing stage, correlates directly with the power transmission reliability. The problem of a practical power transmission, design has been solved by developing of a methodology suited to the purpose. The basis of the developed design represents a contemporary approach to designing, comprising the phases of conceptual, preliminary and detail designs, with applying of the reliability design method within these phases. Approach to technical system design, the algorithms of the developed vehicle design from market-users by reliability preliminary design, detailed reliability design to manufacturing, reliability block diagram are presented in the paper. The developed and applied methodology enables reliability design of the vehicle and its elements, with the objective of obtaining a reliable vehicle which is one of the main requirements for the competitiveness in the market of automotive vehicles.

Opis:: The objective of reliability prediction is to estimate a time of upcoming nonoperational state at the current operational state of a system through real-time monitoring operational parameters and/or performances. Hence, the predictive (proactive) maintenance in industrial systems involves operational conditions monitoring and online forecasting the useful life of machines equipment to support the decision-making process in selection of the best maintenance action to be carried out. The advanced warning of the failure possibility can bring the attention of machines operators and maintenance personnel to impending danger, and facilitate planning preventive and corrective operations, as well as inventory managing. This problem has been extensively studied in many scientific works, where the predictive models are based on the data-driven approaches that can be generally divided into statistical techniques (regression, ARMA models, Bayesian probability distribution estimation, etc.), grey system theory, and soft computing methods. The artificial intelligence is frequently addressed to the predictive problem by utilizing the learning capability of artificial neural network (ANN), and possibility of nonlinear mapping using fuzzy rules-based system (FRBS) or recognizing and optimizing data-derived pattern by using evolutionary algorithms. The paper is a survey of intelligent methods for failure prediction, and delivers the review of examples of scientific works presenting the computational intelligence-based approaches to predictive problem.

Opis:: Systems of transport means operational use are such systems whose main goal is to carry out transport tasks on an assigned territory. In each transport system assurance of the used transport means availability, viewed as the object capability to accomplish the transport task, is of great importance. A certain number of damages results from natural wear of transport means elements which is a natural phenomenon, whereas other damages can be caused by in effective repair of the previous damage. In this way, within a short time, there occur the so called repetitive damages to the repaired element. This reflects improper organization of repairs, poor skills of the maintenance workers, limitations connected with wrong diagnosing before and after the repair. Damages occurring during means of transport operation involve bearing considerable costs while assuring the transport means operational reliability, as well as covering the losses connected with impossibility to accomplish the transport task. Finding out the causes of in effective repairs would reduce the costs that a transport company has to bear to provide efficient operation of means of transport. Times of resultant repairs and being unftt for use have been analyzed, as well as costs of repairs, spare parts, maintenance and operation.

Opis:: This paper presents a framework for the reliability characteristics estimation on the experimental data. The framework consists of the set of failures, the experimental data sources, the set of reliability characteristics, the estimation methods, the estimation goodness tests and the expert system supporting estimation and statistical inference processes. The experimental data was obtained with two main theoretical means: control theory and diagnostics. It has been observed that changes of the functioning condition potential could serve to determine the symptoms of transient (momentary) failures and the changes in the potential of the technical condition to determine the symptoms of parametric faults. Such an information is sufficient to calculate reliability characteristics before dangerous catastrophic failures occur and to calculate reliability characteristics for single object without having to deal with a numerous set of objects. The set of reliability characteristics models consists of the analysed failures combination and distribution functions used in the reliability engineering. The set of estimation methods includes analytical and numerical ones. The proposed expert system supporting estimation and statistical inference processes consists of data base (the experimental data), rule base and inferring machine.

Opis:: It can be assumed that at least some of the systems associated with the train traffic operation work in the “mission” mode, i.e. their availability and operational dependability are related to safe “move” of a train through the strictly defined section of the railway line, i.e. systems (devices) must operate reliably during “mission”. In the remaining time, operation of devices does not affect the safe train traffic operation. For example, it is possible to list crossing signalling systems or the GSM-R system, which along with the ETCS 2/3 system, constitutes the ERTMS system. In the article, the GSM-R system operation analysis, in terms of the above-mentioned factors, is presented. In general, it can be assumed that the GSM-R system devices (e.g. BTS base stations) should be efficient within the specific periods, i.e. during the train passing through the relevant section of the railway line. According to the authors’ calculations, it is stated that within longer periods, the selected GSM-R system devices (BTS stations) cannot be fully efficient, i.e. possible failures occurred and removed in these periods will not affect the safe train running.

Opis:: Improving safety and reliability of ship propulsion system during dynamic positioning (DP) operations of multipurpose vessels is an essential advantage. It may be such possibilities obtained by application the considered solutions of propulsion systems and all other elements of energetic system. The minimum requirements were determined by creating the regulations of dynamic positioning systems and their levels. Applying the solutions, which were exceeded the limits of basic requirements, allows to increase the safety and reliability levels with a low rise the investment costs. Many marine companies try to invent so low cost solutions. An example analysed in the paper is the Wartsila LCC system. The applications of more complicated solutions in comparison to required duplicated systems are expensive. The cheaper solution is an investing in the development of automatics configurations (for those systems it was applied the triple and quadruple configurations) which in transient or emergency conditions may obtain the time delay making possible a support of industry part work and DP systems. In emergency situation, after the loss of position by DP system, the power management system allow the safe break of work the industry part and return to work after elimination the critical condition.

Opis:: The presented paper concerns with the technical object reliability evaluation based on the parametric and momentary failures during the process of object operating. The real world data observation shows that in the case of high quality technical objects the catastrophic failure events are too rare to the credible evaluation of the object’s reliability. For that reason, the parametric and momentary failures are in the centre of attention in this paper. The set of analysed failures was obtained with the classifiers of the field data provided by the monitoring system (the failure alarms) and the diagnostic system (the functional and technical condition parameters deviation). The changes of the functioning condition potential are used to determine the symptoms of momentary failures and the changes in the potential of the technical condition to determine the symptoms of parametric failures (non-total). The assumed reliability characteristics model has the form R(t) = f(_, Rb(t), Rc(t)), (where: Rb(t) and Rc(t) – the estimators of reliability for parametric and momentary failures, symbol ‘_’ denotes catastrophic failures not covered). For the identification of R (t) as an analytical function, the estimators are computed with the field data. The Weibull distribution function due to its flexibility is often used. Such is the case in this paper. Two parameters a and b known as the scale and the shape parameters are estimated with the computerized procedure realizing least-square method. The presented examples show good fit quality even for small set of data.

Opis:: The article presents a data analysis and processing for tuning artificial neural network (ANN) of the anthrop technical system reliability, based on the opinions of experts. In general, the system reliability parameters are functions of operands – physical values – like time to failure, time between failures, duration times of specific reliability or operational states, number of failures in a time interval (event frequencies). These values are easier to be determined by an expert – operator with long year experience – than probabilistic model parameters. It is suggested that they be used in elicitation, for example linguistic estimates of the shares of reliability system elements in the system failure frequency. The numerical – linguistic elicitation of these opinions was carried out, which turned out to be uncorrelated and not suitable for tuning the network. Data processing method was used with the appropriate adopted analytic hierarchy process (AHP) geometric scale and matrix approximation method evaluations (logarithmic least squares method). Correlation analyses were performed for received input and output data of network and error of data processing method was determined. The results are shown in the example of elicitation and data correlation analyses for tuning the reliability neural network of the ship propulsion system.

Opis:: Due to the need to reduce greenhouse gas emission rate, nowadays vehicles are manufactured in different types of fuel injection, one example is the engines with electronic injection and management. This vehicles present several advantages for the environment and it reduces the amount of fuel used in the vehicle, becoming more economic, what is also important due to the prediction for decrease of the available quantity of fossil fuel. The mechanical injection vehicles are no longer manufactured what make the electronic fuel injection engines to begin to be introduced in Cape Verde. The biggest problem in Cape Verde, when it comes to maintenance of vehicles, is the fact that the majority of mechanics working in vehicles maintenance, learned with the practice, very few of them had the opportunity to study. These new vehicles require staff with a certain level of knowledge. Mechanics and workers generally have an elementary school education; or have never finished high school. Many of them began working as apprentices and were trained on the job by more experienced staff. As a result, most of their skills were acquired on the job in practical “hands-on” contexts without any theoretical training. This paper aim to study the state of the art related to maintenance problems and strategies in electronic fuel injection engines, as well as the study of problems faced in Cape Verde with the maintenances. This paper will propose a solution for a reliable maintenance, for these devices in countries with lack of technical support focusing in the study of case in Prai city, Cape Verde.

Opis:: Analyzing the systems in terms of reliability, we often treat them as the technical objects only, omitting human interaction or assuming that operator has constant characteristics. This significantly distorts the results obtained in this way, since human is a part of the system with special properties that can change together with the predisposition of the operator and the conditions under which he operates. These attributes may have a major influence on the reliability of the systems. Therefore, analysis of systems reliability should include a reliability of operator and its properties. In this paper presented the antropotechnical reliability structure based on selected installation, which is a part of ships propulsion system. Also operator’s functions were defined and the analysis of human reliability, taking into account various properties of the operator and the external conditions, were performed. Then, there is assessed the influence of operator and environmental factors on the value of the entire system reliability. The study used the reliability data of the container ship propulsion system equipped with low-speed piston engine, fixed pitch propeller and auxiliary installations. These data were obtained from studies of expert judgments (Brandowski A., Frąckowiak W. et al.) in the years 2007–2009. For HRA (human reliability analysis), HEART technique (Human Error Assessment and Reduction Technique) was used, together with the human unreliability values and correction factors developed by the authors of this method. Study results illustrate influence of environmental, ergonomic factors and the properties of the operator on the reliability of the antropotechnical systems. The studies were subjected exemplification on fuel treatment installation as a part of ships propulsion systems.

Opis:: The economizers are used for production of steam heating on en route ships. The economizers are producing steam in a heat exchange process from the ship's main engine exhaust gas. Products of the incomplete combustion of the heavy fuel oil remaining in engines, passing the boiler, collect on the heat exchange surface of the economizer. When the incorrect assumptions are made for the boiler operation conditions, the boiler steam capacity drops and fire and burning of the incomplete combustion products can occur in the economizer. To minimize combustion product quantity that collects on the boiler surface, the allowable exhaust gas pressure drop in the boiler should be taken into consideration, as well as the results from recommended exhaust gas flow velocity that is determined by main engine service load determined in the preliminary design phase of the ship. The remaining operating conditions are made in such a way to obtain high steam capacity of the boiler. It is essential at the design stage to take into consideration the future operating parameters of the combustion-steam-water installation, since these parameters depend on the choice of boiler and determined at the design stage production of steam. On the basis of operation parameters of contemporary container ships, an attempt was made to select economizer capacity in the preliminary design stage taking into consideration operation conditions of the propulsion system-steam installations unit in aspect of economizer reliability.
