The complexity of software for improving and monitoring processes related to the repair and maintenance of equipment at industrial enterprises is an automated system for the maintenance and repair of equipment, which plays an important role in the market planning of equipment maintenance and repair. Due to the fact that there was a need to write software for calculating economic standards in the market planning of equipment maintenance and repair, a program was written. The introduction of the software in the market planning of equipment maintenance and repair is economically justified in terms of reducing the cost of repairs, reducing losses from equipment downtime. The software product will allow you to calculate a scientifically grounded indicator of the costs of capital repairs of fixed assets (lifting equipment) for the 1 category of repair complexity; scientifically grounded indicator of working capital for overhaul for the 1 category of repair complexity; scientifically grounded indicator of material costs for the 1 category of repair complexity during overhaul of press-forging equipment, forging-steam-air hammers; scientifically grounded indicator of material costs for the 1 category of repair complexity during overhaul of lifting equipment; scientifically grounded indicator of material costs for the 1 category of repair complexity during overhaul for foundry equipment; scientifically grounded indicator of material costs for the 1 category of repair complexity when carrying out overhaul of machine tools; the cost of repair work of technological equipment for the 1 category of repair complexity; calculate the market value of the equipment, which is adjusted by the coefficients of physical, functional, external, and moral wear. In the paper, the proposed software for calculating economic standards in market planning of the maintenance and repair of equipment is written in C# Sharp using the framework .NET Core 3.1. The program implements two classes - Program (main class) and Formula (formula class). The formula class encapsulates all the properties and methods of the formula necessary to work with it, including input, storage of all entered values. The main class consistently creates objects of the formula class and executes the methods necessary for the calculation. The paper contains links to the source code and the program. The software allows you to multiply the efficiency of the project management for the equipment maintenance and repair .

The Cost

Modern methods to calculate the operating (operational, maintenance and repair) component of the cost of electricity for nuclear power plants (NPPs) include the number of disparate techniques calculating the cost of materials, labor costs, machinery and equipment depreciation and amortization, overhead costs, and others. Maintenance and repair expenses (MRO) amount to approximately 20 % of the electricity cost. As a rule, they are calculated in fractions (percent) of amortization expenses. Subsequently it leads to a significant deviation of actual costs from the planned ones, making resource planning more difficult. Thus, the development of unified calculation technique of NPP MRO cost is a highly topical issue. The study is based on Russian and foreign research in the field of enterprise and industry planning and management, published in scientific periodical publications and Internet. Analytical, logical, and engineering-economic analysis are applied. This paper represents an attempt to systematize the organizational and methodological support of MRO implemented at Russian NPPs. The result of the study is the development of MRO cost calculation technique which considers the peculiarities of planning, preparation, arrangement and carrying out of NPP repair work. The technique counts rationing of labor, equipment, and materials costs; calculation of repair personnel wage including the allowances, surcharges, and bonuses for work in severe environment (high / low temperature, restricted conditions, work at height, in special clothing and with the use of personal protective equipment, etc.), in ionizing radiation environment. The method to calculate each component of the NPP MRO cost considering the fact by whom repair works are carried out (NPP staff or contractors) is given. The developed technique provides an increase of the accuracy of calculating the NPP MRO cost causing the timeliness and resource availability planning. It leads to NPP economic efficiency in the domestic and global nuclear technology market.

Abstract Rational solution for mining equipment based on the use of haul trucks, excavators, wheel loaders and crunchers should result from thorough analysis of technical and economic issues – both cost-related and exploitational - which can have a crucial impact on the cost of minerals extraction. Moreover mining equipment should be selected with consideration for all vital parameters in specific exploitational conditions and even the exploiter’s preferences. This selection should consider hitherto disregarded criteria, such as mean availability and structure utilization of machinery systems with the aim to improve the same. Methodology presented in the paper illustrates practical application of MCDM and one particular method of this type – the Analytical Hierarchy Process (AHP) – for resolving the problem in specific exploitational conditions of mineral resource in surface mining AHP method covers a multi-criteria approach based on a compensation strategy to model preferences and assuming variant comparability. Taking into account the preferences of the evaluator, which determine the subjectivity of comparative evaluation, is the core of the multi-criteria approach, which treats such preferences Considering the above issues, the following paper is an attempt to develop new and universal criteria as well as a method of evaluation and selection of means of mining equipment for mineral resource surface mines.

Nuclear power plants (NPP) are subject to stiff requirements as to the cost effectiveness of their operation. However, since the NPP operation may be associated with the occurrence of severe environmental, social, political, material and other consequences as the result of nuclear and radiological accidents at NPPs, ensuring the specified level of the NPP safety is an operational task of the utmost importance. The current practice of the NPP design and operation suggests that the objectives involved in improving the efficiency of operation and those of ensuring the NPP safety level required by federal standards and regulations (NP-001) are achieved in isolation: no issues of ensuring high efficiency of the NPP operation are taken into account when addressing the issues involved in ensuring the safety of the NPP and, vice versa, it is a priori assumed that the required level of safety is ensured at any time when high efficiency of operation is achieved. The reason for this is the absence of procedures that make it possible to assess, in an integrated manner, the interdependence of economic and technological factors. The paper describes some of the methods to raise the efficiency of the NPP operation by selecting the best possible NPP maintenance and repair (M&R) strategies leading to high utilization and capacity factor values. A distinctive feature of the proposed techniques is that the efficiency of the NPP operation is proposed to be improved while ensuring at the same time the required level of the NPP safety with any NPP configuration.

Currently, the penetration of industrial robots into all sectors of the economy is increasing. However, there is an acute problem of conducting preliminary tests. The use of the digital twin as a replacement for the industrial robot is driven by high economic costs. In order to reduce the cost of the project, a solution is proposed to conduct preliminary tests on the developed model. The article developed a mathematical model of one of the drives of the industrial robot manipulator Yaskawa Motoman MH50-35. The model is suitable for researching the movement of the robot' tool. A mathematical description of a permanent magnet synchronous motor SGMJV-09A in a rotating coordinate system is given and a block diagram of the power part of the drive is made. A system for regulating the position of the robot's tool with a nonlinear position controller has been synthesized. Based on the results of modeling the operation of an electric drive in the Matlab Simulink environment, the degree of correspondence of the developed model to a real object was assessed and conclusions were drawn about the limits of its applicability for studying the operation of an electric drive of a robotic arm. The accuracy of working out the task for turning the wrist is 0.0001 rad, there is no overshoot in position, and the time for completing a full turn of the tool is 1.07 s.
