The «1C:ERP» application solution consists of functional blocks, each of which is a subsystem that includes a set of specific tools and settings that provide a certain number of functions. Due to the flexibility of all settings, the standard configuration of 1C: ERP can be adapted to different features of different enterprises. One of the interesting mechanisms that are implemented in this applied solution is the mechanism of intercompany sales of "Intercompany". This mechanism is very relevant in the modern realities of trade. For companies represented by several legal entities, "intra-company trade" is available for the sale of goods belonging to another organization. Here is one possible example of such a sales scheme: the purchase of goods to the warehouses of an enterprise is handled by one holding company (organization); sales of goods can be performed by the holding company (organization) that is allowed to sell the goods of the purchasing company; at the time of sale, the final buyer is controlled by the possibility of selling goods to another organization in accordance with the configured sales scheme between organizations; sales documents between the purchasing firm and the selling firm are drawn up based on the results of sales of goods to the end user. Making a sale of a product on behalf of another organization is no different from selling your own product. If the merchant organization does not have the required quantity, the system automatically writes off the missing items from the organization for which intra-company operations are allowed in the transfer settings. Despite the beauty of the description of this mechanism, there are a number of problems that users face when using it. In this regard, the purpose of the work is to describe the "Intercampany" mechanism and present a way to solve some of the problems that arise when using it. An important element of the Intercampany subsystem is the process of forming reserves (creating records in the accumulation register "reserves of goods of organizations"). A special feature of the new accounting register is that it does not store a history of data. This is not very logical for the accumulation register, and should be taken into account when configuring the system. At the same time, the register "reserves of goods of organizations" may contain entries related to unverified documents. This may occur after the goods receipt document is canceled, if this cancellation results in negative balances for the organization. As a result, records that form a reserve that covers these negative balances will be linked to the undelivered goods receipt document. Therefore, one of the methods to solve this problem is to forcibly delete entries from this register.

The article is devoted to the possibility of sharpening images intended for electronic publications through the use of mathematical filtering algorithms. It is believed that the processing of images with special filters can increase their sharpness, but in conditions of visual perception from the screen of an electronic device, the use of some filters does not always give a significant increase in sharpness. This is due to the physiological features of the structure of the human visual system, which works as a low-pass filter. If the degree of filter impacts is insufficient or the mathematical algorithm underlying the filter itself will show low efficiency under visual perception conditions, the sharpening results of image details can be completely lost. On the other hand, for the final consumer it is important to reproduce precisely those image details that relate to informative areas, which are perceived by the human eye and which determine the plot content of visual information. Thus, the effectiveness of application sharpening filters is determined by the effectiveness of their impact on the informative areas of the image. For reaching the purposes of this article, evaluation of the effectiveness of sharpening filters in terms of visual perception of final images by the consumer is carried out by the method of spectral analysis. A comparative analysis of the spectra obtained for images processed using various sharpening algorithms allows us to judge the real change in sharpness, as well as the effectiveness of the implementation of these algorithms in terms of visual perception of the image. The results of the study can be used to develop recommendations for choosing the necessary sharpening algorithm, depending on the nature of theimagesd.

The article examines the relevance of the development of the scientific social environment in the form of a ConfID Web application. One of the important aspects is the implementation of the mechanism for the automated accumulation of achievements, which may include patents, personal electronic certificates, output data of publications, and participation in conferences. The ConfID project plays the role of a portfolio, on the basis of which the profile of each participant is formed. Any participant has the opportunity to look for fellow scientists in order to conduct cooperative research to help with reviews on dissertations and act as their opponents. The proposed configuration model of electronic certificates will optimize resources for data storage, as well as their processing. The ecosystem under development consists of two main projects - ConfID and ConfLab. Due to the possibility of interserver interaction between projects, the full life cycle of scientific events is provided. An important aspect of the problem being solved is the documentary support of scientific flows at all stages of the life cycle. Particular attention was paid to the description of the algorithm for generating and storing graphic documents such as letters and other related materials. It is such documents that form the basis for filling the scientific portfolio of both a young scientist and a senior researcher. The project presented in this work demonstrates a complex technical solution in the form of an architecture that ensures the interconnectedness of disparate scientific communities by aggregating heterogeneous data on the scientific achievements of practical scientists. Among other things, the architectural solution of the system itself is of scientific interest as a model for applying the best practices for constructing systems of this kind.

The problem of creating highly efficient algorithms for identifying critical events as part of decision support procedures in technological management is considered. The article proposes an approach to increasing the power of the nonparametric Wilcoxon criterion for decision making in situations with violations in compared data samples of the type "vertical displacement" and "scale". The modified Wilcoxon criterion is considered as a tool for identifying deviations in the conduct of the technological process, which do not exceed the threshold values, but have a significant impact on the technical and economic indicators. The proposed method of identifying critical events using the modified Wilcoxon criterion makes it possible to determine both the fact of the presence of an event and, in a number of cases, their identification. The article proves that the power of the proposed modified Wilcoxon test does not deteriorate compared to the traditional Wilcoxon test. The problem of detecting significant deviations in the accounting of electricity consumption at the boundary point of the grid company and the consumer from the parameters established by contract is reviewed as an example. Electric meters supposed to be the information sources in this case. The data received from smart meters is usually represented in the form of so-called “load profiles”. The performed numerical experiments through the example of processing the credentials for the power consumption of one of the petrochemical industrial enterprises allowed testing the possibility of using the modified Wilcoxon criterion as part of an effective element of the algorithm for detecting critical events. Also, the problematic issues of inclusion of this module in the automated decision support system for technological management are identified and the corresponding software is proposed.

The article discusses the development of information and algorithmic support for a system for optimizing the control of the synthesis of continuous active pharmaceutical ingredients (APIs) by the example of continuous synthesis of diphenhydramine from chlorine/ bromodiphenylmethane on microreactors. The methodological basis of the proposed development is a systematic implementation of the Quality-by-Design (QbD) principle at the stage of development of continuous synthesis of APIs. Information modeling of the synthesis of diphenhydramine in flow-type devices (microreactors) was carried out. The scheme of an intelligent information support system for the synthesis of diphenhydramine (diphenhydramine) has been developed. The developed intelligent system includes a block for the preparation of managerial decisions, which is intended to formulate on-line recommendations to a researcher conducting synthesis of finished dosage forms (SFF). The main task that is solved using this unit is to predict the quality index of the synthesis process and at the same time determine the critical values of the synthesis, which allows the researcher not to go beyond the given limits. The basis of both the prediction model of the quality assessment indicator and the critical parameters of the process are the ideas of regression analysis. An algorithm for constructing multi-feedback regression equations is presented. The constructed regression equations make it possible to formulate the optimization problem at the second stage, for the solution of which one of the modifications of the coordinate search for the optimum was chosen - the Hook - Jeeves algorithm. A generalized block diagram is presented, which reflects in its most general form an algorithm for optimizing research planning in the continuous synthesis of diphenhydramine. Some results of studies of the continuous synthesis of diphenhydramine on the eduFLOSYS microreactor system are considered. Chlorobenzohydrol and bromobenzohydrol were used as starting components.
