The importance of improving the efficiency of the system of service activities for the maintenance of machine-building products has been outlined. Individual types of service and their features have been analysed. The indicators that determine the effectiveness of service activities by type, the criteria for their evaluation and the most favorable trends in the process of working out the production of certain types of goods have been considered. It has been noted that the service of machine-building products is quite an expensive item of the production activities of enterprises. To justify the costs of warranty service, it is necessary to have certain statistics of product failures and its individual elements for their additional production in order to ensure timely provision to the consumer. The analysis showed that the costs of all types of goods servicing are an important indicator of its organization by enterprises. Statistics for keeping records of all types of product maintenance allows you to improve its production, plan the production of spare parts and reduce the cost, which is an important element of competitiveness.

AbstractIntroduction. Effective management of road indstry is particularly important in conditions of limited funding, as it is not possible to provide adequate funding of the economic entity that has the functions of a customer service. The cost of the customer service maintenance depends directly on the compliance with applicable regulations for these works cost determination. One of the aspects that form a considerable part of the costs of customer service is the maintenance of service vehicles.Problem Statement. Road services in the regions (hereinafter RSR) are the recipients and managers of the funds from the State Budget of Ukraine that are directed for the development and maintenance of public roads of state importance, being as well the asset holders of these roads. To perform their functions, the RSR have vehicles on their balance, the use of which involves a number of costs, including fuel and lubricants, repair, maintenance, replacement of tires, etc. The most important of the steps involved in setting the costs of vehicle maintenance is the process of cost planning. Planning has to be based on the structure of the vehicle fleet (own or leased), functional responsibilities and scope of road works.Planning is carried out for vehicles on the balance of the RSR, as well as for leased vehicles. In the case of leasing, the costs mentioned above are added by the vehicles leasing costs. These costs must be forecasted, justified and performed within the approved cost estimates of the customer service expenses.Purpose. The purpose of the article is to highlight the theoretical and methodological approaches to the calculation of planned costs for the maintenance of service vehicles of the road works customer.Materials and methods. Dialectical methods of knowledge, such as analysis and synthesis of fleet composition characteristics and approaches to cost planning methods, as well as induction, were used in writing the article to explore some aspects of the process of calculating the planned cost of maintenance of the road works customer's service vehicles.Results. The study highlights and describes the main approaches to the calculation of planned costs for the maintenance of service vehicles of the road works customer. The methodology of calculation of planned costs for the maintenance of service vehicles is explored.Conclusions. The introduction of a clear methodology and analytical toolkit for calculating all necessary expenditure items for the maintenance of the road works customer's vehicles in the cost planning process will establish the implementation of a clear mechanism for calculating the planned costs of maintenance of the road works customer's vehicles. It will also provide an automated information-analytical complex for planning of cost estimates, with information entry and reporting in standard forms and possibility of prompt response to changes in fleet composition, needs for spare parts, repairs or other expenses for the maintenance of service vehicles and making changes in cost estimates.Keywords: motor vehicles, costs, cost planning, customer service, maintenance of service vehicles

The presented article analyzes regional markets, for heavy industry and machine building products for the Azerbaijani economy. In terms of trade relations and territory, the markets of Turkey, the Russian Federation, Georgia, the Islamic Republic of Iran, Moldova, Belarus, Ukraine, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan and Armenia were selected and evaluated. The database of the study consists of mutual import and export data for the mentioned countries in 2014–2018. Based on the import-export data collected covering the years 2014–2018 on six-digit codes of regional markets, the revealed comparative advantage and localization coefficients on import and export were calculated. As a result, importing and exporting countries have been identified in the regional markets through the calculated coefficients for each of the 5 years of heavy industry and machine building products considered. Thus, in terms of imports and exports, the countries with the highest coefficients were selected.

The efficiency level of the banking industry is the most important indicator to identify the soundness of banking system. This paper use non parametric frontier approach, DEA, to analyze the Islamic bank efficiency in ASEAN. We use price of deposit from customers, deposits and placements of banks, labor, and others operational expenditures as control variabel, and using financing, deposits and placements on other insitution, securities, others investment as output variabel. We found that the mix bank is the most efficient group within the observation period. Furthermore, the average Islamic banking efficiency in Indonesia, on intermediation approach, is lower than the average of ASEAN, unless they can reduce the cost of labor and other operational expenses. This paper also examines the determinant of efficiency of the Islamic Banking in ASEAN. Internal factors are Total Aset, ROA, BOPO, and ETA, and external faktor are Market Power and Inflation. Using Tobit regression, the result shows the factors that most influence to the Islamic banking efficiency in Indoneisa is the total size of the bank or its assets, OPEX/OR, and Market Power.

Technological parameters for electroplating cadmium alloy (Cd (24)-In and Cd (33)-Sn) coatings from low toxic solutions have been proposed. Since the fabricated alloy coatings possess low internal stress and microhardness, good adhesion property, high corrosion and wear resistance, they can be used as protective coatings for machine building products to enhance reliability and operability thereof. The presence of good solderability and low values of transient electric resistance in climatic testing favor these coatings to be applied in hetero-structured contact systems of instrument making products for increasing their reliability and operability in a tropical marine climate.

Over the years, Wagner’s (1975) heuristic rules appealed to the practitioners because they had simple data requirements, were easy to understand and hence easy to apply. In his algorithmic solution, Wagner assumes that the exact distribution of demand (during lead time) is known. If such a distribution is not available, he recommends using the normal distribution. The author’s purpose is to compare the cost of the solutions provided by Wagner’s (1975) heuristics to optimal (Archibald & Silver, 1978) and determine their quality. Their second goal is to perform sensitivity analysis on the results with respect to demand’s skewness, the ratio of ordering cost to carrying cost. The author’s third goal is to use as much actual data as they possibly can.

This paper presents the use of Weibull formulation to the life analysis of different parts of the engine in order to estimate the cost of maintenance, the direct operating costs (DOC) and net present cost (NPC) of future type turbofan engines. The Weibull distribution is often used in the field of life data analysis due to its flexibility—it can mimic the behavior of other statistical distributions such as the normal and the exponential. The developed economic model is composed of three modules: a lifing module, an economic module and a risk module. The lifing module estimates the life of the high pressure turbine blades through the analysis of creep and fatigue over a full working cycle of the engine. The value of life calculated by the lifing is then taken as the baseline distribution to calculate the life of other important modules of the engine using the Weibull approach. Then the lower of the values of life of all the distributions is taken as time between overhaul (TBO), and used into the economic module calculations. The economic module uses the TBO together with the cost of labour and the cost of the engine (needed to determine the cost of spare parts) to estimate the cost of maintenance and DOC of the engine. In the present work five Weibull distributions are used for five important sources of interruption of the working life of the engine: Combustor, Life Limited Parts (LLP), High Pressure Compressor (HPC), General breakdowns and High Pressure Turbine (HPT). The risk analysis done in this work shows the impact of the breakdown of different parts of the engine on the NPC and DOC, the importance that each module of the engine has in its life, and how the application of the Weibull theory can help us in the risk assessment of future aero engines. A detailed explanation of the economic model is done in two other works (Pascovici et. al. [6] and Pascovici et. al. [7]), so in this paper only a general overview is done.

Experience gained from the use of buses in urban conditions showed that the working conditions of friction elements of the braking system, ensuring traffic safety, are associated with high loads. This leads to the intensive wear and premature replacement of the worn friction components, which reduces the overall reliability of the brake system and road safety. On the other hand, the friction linings of brake mechanisms may act as abrasives that cause the wear of brake discs or drums. Their replacement during operation is associated with a significant increase in the cost of spare parts. Therefore, it is assumed that the determination of the tribological properties of the brake linings in the brake mechanisms, before their exploitation, will increase the efficiency and safety of the vehicles’ operation, which justifies the choice of the research subject matter for its real and practical significance. The paper presents the preliminary results of the research into the main elements of the brakes in a city bus on a test stand mapping the real working conditions. For the testing, brake shoes of different manufacturers were used. Their tribological characteristics, reasons for their wear, and operational recommendations were determined.
