Optimization of the production plan taking according to the customers’ strategic importance
Authors: Baranchikova S G , Ershova I V , Klyuev A V , Cherepanova E V 
Published: December 2020

Abstract
The article is devoted to the management of the production plan of the industrial enterprise. Existing approaches to optimization of the production plan are focused mainly on stochastic demand and consider the process of production plan formation. At the same time, many modern industrial enterprises often deal with rush orders in the course of their work. They have to solve the task of changing the formed production plan. If resources are limited, the decision to include an urgent order may result in a failure or a change in the due date of the orders included in the plan. In this regard, it becomes important to take into account the strategic importance of clients to the enterprise. The article proposes a methodological approach to the issue of inclusion or non-inclusion of rush order in the already formed and accepted production plan. The authors have developed a mathematical model of optimization of the formed production plan with the participation of rush order. The model uses Boolean variables to decide whether to include or refuse an order and an additional factor to increase margin income from the order for strategic customers.

Modernization of an industrial passive exoskeleton prototype for lower extremities using rapid prototyping technologies
Authors: Karfidova A O , Vasilyev M V , Morozova I G 
Published: December 2020

Abstract
The work is devoted to an urgent problem: increasing the efficiency of exoskeleton design. Such devices are needed to perform work that requires high physical activity in various production processes [1-18]. Currently, there are no industrial exoskeleton designs that meet the needs of customers [19-30]. To determine the effective design option, analogues of foreign and domestic markets are studied [31-33]. Based on a comparative analysis of characteristics, it is revealed that the Russian exoskeleton developed by Karfidov Lab LTD. [34] has the highest performance in comparison with competitors. However, this design lacks a convenient system for fixing the saddle to support the user, and the exoskeleton has a large weight - 6 kg. As a result of the work performed, some modernization is proposed, taking into account the solution of problems. For this, a solid 3D-model in the SolidWorks environment and design documentation for exoskeleton production are developed. To reduce the exoskeleton weight, it is decided to use plastic parts. Support for the user’s body is provided, made in the form of a vest, as well as fixation system in the form of belts located on the foot, lower leg and thigh. It is decided to install a gas spring from the manufacturer Suspa, model Varilock EL2-111-79- 600N, which enables to increase the shock absorption when the exoskeleton is active. To increase the strength of plastic parts, a reinforcement method is used. A saddle is introduced that provides a soft contact between the user and the system in the active and passive positions of the exoskeleton.

Authors: Midor Katarzyna , Biały Witold , Ivanova T N 
Published: December 2020

Abstract
In view of the increase in population’ wealth and thus in the quality of life, the number of individual transport means is increasing significantly. Today’s society values comfort and freedom of movement, and consequently is not willing to use public transport on a mass scale, which always entails certain restrictions. However, in a situation of recurring congestion, especially in urban and industrialized areas, as well as increasing air pollution caused by emissions of harmful substances from the combustion of oil-based fuels, it is necessary to ask a question whether we should not seek solutions that would significantly reduce these phenomena. One such measure is the organization of collective transport by companies as an alternative to individual employee commuting. This paper presents the research results that show in a selected area of the Silesian agglomeration on what scale the collective transport organized by the company influences the local congestion and emission of harmful substances into the air.

Authors: Arhirejskij A A 
Published: December 2020

Abstract
The Assessment of services quality is an urgent task in markets with imperfect information. Car service market refers to markets with imperfect information. Earlier, the author proposed to assess the car service quality by the voluntary services certification system criteria using the generalized principle of Edgeworth-Pareto. To implement this approach in practice, information is needed on the relative importance of the criteria, which can be obtained from regression models. The novelty of this work is the use of regression models without a constant. The information indicators analysis of the obtained models revealed the greatest importance of two of the six criteria. The information obtained is used for multicriteria assessment of the quality of the services and building a car service enterprises rating.

Authors: Lukashuk O A , Letnev K Y , Komissarov A P 
Published: December 2020

Abstract
Specifics of functioning for the drives of main (lifting and thrusting) mech-anisms in an open-pit excavator were determined for their joint action during the process of excavation. It was shown that the operation forms a two-crank lever-age transmission mechanism (connecting the main mechanisms and the excavator bucket) and a common transmission mechanism of the drives (consisting of the main mechanisms and the leverage). It was also established that an initial link of the common transmission mechanism would be a «stick-bucket» link whose co-ordinates determine positions of every other link in the mechanism in relation to the stand (a boom). Dependencies were derived for finding kinematic transfer functions of the leverage, that is relations between lifting and thrusting velocities and an excavation velocity when the bucket (its cutting edge) is moved along a given trajectory in the process of pit development. The results of the research could be used for the purposes of designing a control system for the main drives of an excavator.

Authors: Ryazantsev V I , Heng-Xu Li 
Published: December 2020

Abstract
The development of automotive technology is clearly characterized by the mass introduction of numerous active safety systems in the design of cars, such as anti-lock brakes, stability control systems, etc. In the conditions of a significantly increased number of motor transport, which is operated on roads of relatively low quality, the question of increasing the stability of the car when driving on uneven roads naturally arises. There are quite a lot of such roads in countries with large territories. There are numerous cases of the formation of sections with regular profiles on improved roads. Movement in such areas can cause resonant vibrations of unsprung masses, which, in turn, leads to a loss of stability of the vehicle. This article discusses the effectiveness of various structures of controlled suspensions that can be used in the stabilization system of vertical reactions of the road to the car wheels when driving on an uneven surface.

Authors: Ushkalov V , Mokriy T , Malysheva I , Lapina L , Pasichnik S , Bezrukavyi N 
Published: December 2020

Abstract
A brief description is given of the comprehensive modernization of standard freight car trucks through the use of devices of American companies adapted for railways with a 1520 mm gauge and wheels with ITM-73 specially developed wear-resistant profile, which allows several times to increase the resource of problematic running gears. An approximate method is proposed for solving the wheel–rail interaction problem with determining the position and size of non-elliptic contact patches, including with conformal contact. Using this method, new profiles have been developed for turning worn wheels (ITM-73-01), as well as new wheels for cars with an axial load on rails of 23.5 tf (ITM-73-02) and 25 tf (ITM-73-03). The data of experimental studies showed that the average wear rate of the wheel flanges of freight cars with complex modernized trucks equipped with wheels with ITM-73-01 profile is 3.5-5 times lower than that of a standard car with a standard wheel profile. According to forecast estimates, the use of wheels with profiles ITM-73-02, ITM-73-03 will allow to achieve even greater increase in the resource indicators of wheelsets for wear of the flanges.

Published: December 2020

Abstract
The primary task of a greenhouse is to create optimal microclimate, which doesn’t depend on external climatic conditions, to grow plants. We can observe significant air temperature and humidity difference in a traditional greenhouse during 24 hours. The stable microclimate in greenhouses is provided by different engineering systems such as heating, ventilation, lighting, etc. These systems require a lot of energy. Saving energy and reducing the mode of temperature amplitude inside the operating greenhouse during exploitation period can be achieved by using solar energy in the greenhouse heating system, namely, by using heat accumulators. However, the test method of optimal heat accumulator to equalize the temperature amplitude inside the greenhouse wasn’t described in any research. The purpose of this research is to determine the optimal heat accumulator for equalizing temperature amplitude inside the greenhouse under atmospheric effects in spring. The experimental research of the heat-humid regime was carried out for the greenhouse without any heat accumulation. Relationship between the volume and the surface area of the accumulator and its efficiency was identified.
