Opis:: Afghan highlands, landscape and altitude above the sea level, and geographical situation influence on the climate. Engines’ operation are very different from their work in European plains. Mountainous terrain variability has a significant impact on operation mode of the car’s chassis and transmission, and climate change determines the engine performance parameters. Mentioned factors result in technical performance characteristics and their costs. Defining requirements to preventive measures for technical failure would reduce technical repair costs and rational technical maintenance frequency would save funds for maintenance.

Opis:: Reliability is a collective term covering several abilities of the technical system: to deliver required functions, to uphold quality of products and services, to assure that the safety requirements associated with the system are properly fulfilled with regards both to the users and the environment and finally to uphold the durability of the technical system during its whole life cycle. All this has to be performed at acceptable risks, optimal cost, and correspond to operational needs of the business. Even though there is an advanced, well thought-out concept for this purpose - reliability centred maintenance (RCM) - that correctly applied might result in very good quality maintenance programs, it is not broadly used in the industry due to the vast efforts required for its implementation. An appropriate methodology supporting systematic functional break down of a studied systems, and guidelines how to couple functional failures to failure modes, integrated with RCM, would greatly speed up generating of effective maintenance programs. In this paper we present our research towards development of such a methodology, and show a pilot implementation to analysis of machine tool spindle. The methodology is based on Hubka's theory of design and AFD/TRIZ.

Opis:: Reliability-Centred Maintenance (RCM) implementation provides measures that signify progress towards implementing an RCM based maintenance program. Using numbers identified during the Analysis Phase as a basis, the metrics concentrate on the number and percentage of each category (new task, modified task, cancellation of specified old program tasks, design modifications, operational procedure changes, etc., that have actually been implemented. Implementation will (or should) usually begin during the Analysis Phase of an RCM project, and may provide information for improvement of the analysis. Implementation involves many activities, such as: Identification of resources (money, time, manpower), Coordination with governing authorities or other parties affected, Procedure writing, walk down and approval, Procurement of special tools, parts and consumables needed to carry out the procedures mandated under the new program, Training or at least orientation on the new procedures for those who are to perform them, Planning and scheduling of new RCM based procedures, Actual execution the first time on the asset that was subject of the RCM Project.

Opis:: Machine failures have destructive effects on continuity of operation and lead to production losses in long-wall mines, making proper maintenance scheduling essential. This paper models the reliability of the whole production chain in an Iranian long-wall mine including the drum shearer, Armored Face Conveyor (AFC), hydraulic powered supports, Beam Stage Loader (BSL), and main conveyer belt. Analyzing the computational results and failure frequencies, we rank the critical components and develop a reliability-based preventive maintenance schedule for all equipment. In respect to the data classification, conveyor belt with failure abundance of 41.5 percent is the most critical, while powered supports with the failure abundance of 1.2 percent shows the best performance. Approximately, the reliability of the production process after four hours reaches nearly to zero. Implementing the schedule, computational results suggest an increase of approximately 67.7 percent in the average production per shift.

Opis:: The new maintenance system of semi-trailer combination as a most used road freight transport means is the subject of interest in this article. The real experiences from practice and creation of the FMEA analysis of the system using software support are the basis of wear and damage analysis of air brake system components used on the semi-trailer combination. The desire to improve market position of the company, customer satisfaction, but also the product specifications, government regulatory requirements, agency recommendations, and legal implications are the grounds for continuous improvement of the product quality, reliability and safety. These reasons push the product manufacturers to perform risk analyses, which helps them identify and minimize system failures during the life cycle of product. One of the risk analysis techniques recommended by international standards to identify possible failure causes is the FMEA methodology. It helps to locate the failures and reduce their consequences, so that the intended function of the machine is fulfilled. In this paper was presented the wear and damage analysis of individual components of air brake system and creating of the FMECA analysis for semi-trailer combination. Base on them, new methods to detect failures of components of air systems, preventive measures and set up of a new planned preventive maintenance system for air brakes was designed. The cost of the proposed maintenance system is 2.2 times higher than the cost of the current maintenance system, but it minimizes the failures and their consequences (traffic accidents).

Opis:: This paper presents theoretical basis for evaluation of the transport system operation quality. A general evaluation model was built, and further part of the paper is to consider the theme of damageability of the means of transport, as a reliability feature, constituting one of the most important criterion to evaluate the transport system operation. Based on the analysed references in question as well as on the results of our own research it has been found that the damages to the means of transport, being utilised within the transport systems, are a result of interaction of various forcing factors. Some number of the damages results from natural wear of the means of transport elements, which is a natural phenomenon, while the remaining damages may be caused by an inefficient repair of the previous damage. This leads to so called secondary damages to the repaired element, occurred within a short time interval, which is a proof of inappropriate organization of the repairs, poor training level of the repairing teams, limits related to pre and after repair diagnosis, which directly affects reliability of the means of transport and consequently the operation quality of the transport systems in which they are being operated and maintained. Based on the analysis of the investigation results it has been found that the primary damages are independent on one another and they occur randomly. The secondary damages are dependent, because their occurrence depends on prior occurrence of the primary damage and the effect of its improper repair or improper repair of the next secondary damage.

Opis:: The article presents the results of expert assessment of the quality of three different branches of trucks in terms of their suitability for long-term rental. The expert assessment is faster and cheaper compared to the analogous evaluation obtained on the basis of operational tests, hence the purpose of this article is to assess the accuracy of the results obtained in expert studies. The reliability characteristics of vehicles, such as: readiness, probability of first failure and distribution of mileage between successive repairs, were used as parameters for empirical quality assessment. Operational tests covered three groups of 30 vehicles. As part of the research, changes in vehicle technical readiness occurring during operation were also assessed. The failures of individual functional systems of the vehicle were also analyzed and compared with the results of expert studies. The expert assessment was based on a questionnaire regarding the overall assessment of the reliability and performance of cars. 32 experts - appraisers, with good knowledge of the construction of cars of the tested brands participated in these studies. On the basis of comparisons of the results of the expert assessment with the results of empirical studies, conclusions were drawn regarding the correctness of the assessment made by experts.

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:: The article aims to present practical methods for prioritising the activities of maintenance departments based on the Pareto analysis and the failure risk analysis. Based on the collected data on the number of observed failures and their removal times, commonly known reliability indicators were determined, which were then used to estimate the probabilities and consequences of failures in terms of the risk of loss of production continuity. Based on commonly collected failure data, the developed methods allow proposing to the maintenance departments the sequence of maintenance and repair work to be undertaken in terms of minimising the risk of failure. Risk analysis is somewhat commonly used in the practice of maintenance departments (e.g. RBI, FMEA, ETA, FTE, HIRA). The added value of this work is the use of reliability indicators for estimating the values of risk components, i.e., probability and consequences. The method was developed on the basis of operational data collected in one of the plants of the dairy cooperative and, after assessing the effects of its implementation, it was implemented in other enterprises of the cooperative.
