Published: May 2020

Abstract
This paper examines manufacturing planning within small-batch make-to-order. Electronic equipment manufacturing companies face challenges caused by increasing numbers of product variants as the demand for individualized products rises. Enterprises have to provide more individualized products instead of standardized ones. Cause of high variation in volumes and high mix of products it is difficult to use common planning tools. Known manufacturing planning methods cannot quickly realize adaptation for efficient use of enterprise capacities. This problem became big challenge for production planners. The purpose of this paper is to understand the requirements on enterprises to use planning and scheduling in small batch make-to-order production. We explore challenges associated with planning strategies. Finally, we consider a functional model of developing a planning system.

Abstract
Vanadium oxides are representatives of a wide class of compounds possessing a metal-insulator phase transition. The properties of both the oxides themselves and their solid solutions with oxides of other metals have been well studied. The question of the possibility of dissolving nonmetallic components in the V-O system and its wobbling on the metal-insulator phase transition remain an open question. The solution of this problem, apart from the scientific side can also have practical significance: in spite of the wide possibilities and uses of vanadium oxides in optoelectronics, microwave technology and other fields, the need to search for materials with given temperatures of metal-insulator phase transition and electro-physical characteristics is obvious. In this paper, an attempt is made to dissolve nitrogen in vanadium dioxide films during their deposition by thermolysis of nitrogen-containing alkoxy derivatives.

Abstract
The development of heavy oil fields has been actively on the agenda. The problem arises due to the depletion of deposits with easily recoverable reserves, as well as due to the large reserves of shale oil and gas. Modern technology is gradually reaching an acceptable level of profitability. Many tasks remain to reduce environmental pressure on the environment. An important step in this direction was made with the introduction of electric fracturing technology. Technologies for isolating the mining zone are being developed. A variety of approaches are used to recover heavy oil. Use formation heating in various ways. Separate formation fluids into fractions in order to diversify recovery methods. Great prospects are opened using combined methods of exposure to kerogen. At the same time, many questions remain on methods for the further development of shale hydrocarbons. This is the development of norms and rules for the development of heavy oil. Coordination of actions of law-enforcement bodies and activity of technology developers is required. It is necessary to develop technological approaches that have shown their environmental effectiveness.

Published: May 2020

Abstract
Laser remote sensing technologies are being actively developed and used, for instance, for modelling the terrain of the surface of the Earth, the Moon and other planets of the Solar System. Theoretical aspect of these projects is underdeveloped and not related to the measurement precision assessment. The article studies the calculation of the potential precision of range measurement and presents a method of calculation of the a space-based lidar parameters based on the condition of providing the set range measurement precision. It produces the equations that connect the potentially achievable precision of terrain (range) measurement and the receiver output signal-to-noise ratio to the lidar parameters and the parameters that determine the external conditions of such measurement. These equations form the foundation for a method of determining the lidar parameters and the requirements acting as the input data for a lidar development. It demonstrates that the space lidar altimeters are rationally associated with the term of the “energy space resolution” as the minimum size of the area of the terrain under resolution under the established range measurement error. The calculations carried out with the said method made it possible to assess the precision parameters of the currently used ATLAS space lidar. According to our data, a lidar is capable of providing the range measurement precision of several centimetres, provided that the objects are located within the area of several tens of cm2. The collected results bring the conclusion of the convergence of the results of the lidar precision calculation, carried out with the developed method and using the data published by NASA.

Published: May 2020

Abstract
Control operations are not related to the creation of material values, so one of the key tasks in economic terms is to reduce the losses arising in the process of control. The article deals with the types of losses that occur during control, as well as losses that are possible in the absence of control, the economic justification of control operations is presented. The result of the control is also affected by the measurement error, so using more accurate measurement tools reduces the loss of internal and external defects due to inconsistency of data and by reducing the number of incorrectly accepted and incorrectly rejected products, but reduces the cost of measurement, while the use of more rough measurement tools reduces the cost of measurement, but increases the loss of internal and external defects. Therefore, when choosing measuring instruments, it is necessary to be guided not only by the permissible error value for this measurement, established in the relevant regulatory documents, but also by the economic component of control. On the basis of the presented material, a method for calculating the savings from using a more accurate measuring tool and the results of evaluating this savings is proposed.

Abstract
In the last few years, in connection with the widespread use of media networks for transmitting multimedia information, it is important to build stegosystems on their basis. The least significant bits for embedding a message can turn out to be ineffective using traditional methods of modification and steganography methods, allowing to embed messages in areas that cannot be significantly distorted during processing by modern encoders, are especially important. One of the tools that allows this embedding is a discrete wavelet transform. Wavelet transform is a relatively new and powerful analysis and processing tool. The method of secret transmission of a text message by hiding in sound files and subsequent recovery without loss is considered in this article. The basic of method is a discrete wavelet transform on biorthogonal wavelets. A web application implementing this method has developed. The implementation language is Python.

Authors: Epifancev K , Mishura T 
Published: May 2020

Abstract
Currently, much attention is paid by science and technology to remote control of hazardous production processes. One of the monitoring tools is the SCADA system, which allows you to evaluate the readings of measuring transducers and promptly report their critical changes to the operator. Of course, this system has certain disadvantages along with its efficiency and high functionality - first of all, the lack of basic methods for checking the system as a whole, evaluating the error, and evaluating the results of the values given. If we think from the standpoint of digitalization, SCADA is an intellectual double, an artificial intelligence that allows us to implement the basic principles of the 4th industrial revolution. The advantages and disadvantages of such systems will be discussed in this study

Authors: Brovkina Yuliya I , Petrakova Ekaterina A 
Published: May 2020

Abstract
The article describes the methodology of structural-parametric synthesis of mechanisms using CAD-tools of computer-aided design. This approach makes it possible to reduce the time required to develop mechanisms schemes for specific engineering solutions and to calculate approximate values already at the development stage of the kinematic scheme. In the mechanism synthesis, one of the main tasks is to determine the operating space and the mechanism output link motion. Using CAD programs to determine the parameters of kinematic schemes reduces design time, and the use of animation functions allows one to visualize the synthesis process.

Authors: Kazachenko A S , Yu Vasilyeva N , Malyar Y N 
Published: May 2020

Abstract
The guar gum was sulfated for the first time with a deep eutectic solvent, a sulfamic acid / urea mixture at a ratio of (1:1). The optimal conditions of the process are shown to ensure the production of guar gum sulfate with a maximum sulfur content (16.1% wt.). The introduction of a sulfate group into a guar gum molecule is proved by elemental analysis. A mathematical model of the process of sulfation of guar gum is calculated. It is shown that the resulting model has high predictive properties. The developed method is environmentally safer due to the fact that it eliminates the use of toxic solvents.

Published: May 2020

Abstract
The article developed a control system for the silo aeration process. The object of control is cement silo. Cement silo is a container for storing dry cement, building mixtures or other finely dispersed materials used in the construction or production of building elements for various purposes. The task is to improve the silo control system for cement storage. Recommended ventilation times for aeration sections for commonly used cement silos are presented in terms of silo volume and the amount of material loaded. A silo aeration algorithm was compiled with alarm signals at the operator’s workstation. Four different silo operation modes were compiled to control the storage of material inside the silo: “normal emptying”, “emptying the outer ring sector”, “emptying the chambers”, “complete emptying”. A control program was developed for the cement silage aeration process in the Unity Pro XL program in FBD language.
