Published: December 2019

Abstract
The article is devoted to the issues of transition of the Russian electric power industry to renewable energy sources. The analysis carried out in the work showed that in the electric power industry there has been a tendency to intensify activities to switch to innovative and renewable technologies in the production of electric energy. The main goal of the transition is to reduce the use of depleted natural resources and reduce the environmental burden. A similar trend is associated with the need to increase the competitiveness of the Russian electric power industry, since in some countries of the world up to 25% of electric energy is generated from renewable energy sources. In addition, in recent years, state programs have been adopted in which by 2024 it is planned to increase installed capacity based on renewable sources to 11 GW. At the end of the work, a structural-logical scheme was proposed that allows for the transition from traditional energy to renewable energy sources. In conclusion, the study presents the main findings and results of the work.

Abstract
Determining the location of the object relative to the observation point is an urgent task in the framework of automation of production facilities. Actively introducing systems to prevent collisions and collisions with pedestrians of self-propelled vehicles, create restricted areas, and control the movement of personnel. The variability of the task and operating conditions leads to the existence of narrowly targeted areas for which generally accepted standard solutions are not suitable. An example of such a technical field is the emergency search system for personnel under the rubble of the rock mass in the conditions of mining. The requirements set by the supervisory authorities require the search team to determine the location of the victim at a distance of up to 50 meters, with an accuracy of at least 2 meters. Issues of underground communications have already been considered in [1], [2].

Published: December 2019

Abstract
The tasks of rational cutting-packaging have long attracted the attention of researchers and practitioners in various industries. They are classified as NP-complete problems. In this paper, two-dimensional orthogonal guillotine packaging in sheets of the same size is considered as the main one. An essential feature of the problem under consideration is technological limitations. You must place all the rectangles of different sizes and quantities, however, the layout template should be the same for all sheets. Thus, it is necessary to minimize the number of sheets in an acceptable time. To compare the effectiveness of various methods on the same class of tasks, the cutting coefficient is determined. However, an important issue in evaluating a particular method is the decision time. The paper presents a heuristic algorithm. The performed computational experiments confirm the effectiveness of the proposed method.

Intelligent data model concepts
Authors: Rudakova G M , Gladkov S L , Korchevskaya O V 
Published: December 2019

Abstract
Traditional database systems have a common flaw: the many concepts that make up their metadata must be predefined. By concept we mean concepts, terms, entities. To create a new concept, you must resort to programming or change metadata. There are a number of tasks for the solution of which it is necessary to manipulate metadata. The data mining model should be based on a dynamic concept model. The concept of a data model and a data set, as an interpretation of predicates, is introduced. Based on many basic concepts, many generated concepts are given. The classification, verification, falsification of concepts and the expanded context of many concepts are also considered. Using this approach will provide the ability to control the creation and expansion of distributed information systems.

To achieve it, several problems are solved – collection of baseline historical data, in the format of event log identify important parameters and patterns in the life cycle status, and making recommendations to improve work with information resource. As an object of research, the article considers the life cycle of service as part of the information process. Service is a reaction of the company’s service Department to the incidents that occur, the consequences of which must be eliminated in a minimum period of time. Process Mining methodology and ProM software were used as the main analysis tools. For the life cycle analysis the additional module Inductive visual miner was applied, which allowed to identify typical chains of life cycle variants, and also to analyze the load of life cycle participants. The analysis showed bottlenecks in the life cycle, “weak links” among the performers, allowed to formulate proposals for improving the life cycle.
Model of optimal organization maturity management under conditions of interference and uncertainty
Authors: Dorrer Mikhail 
Published: December 2019

Abstract
The article proposes a mathematical model of the optimal process for managing levels of organization maturity in the presence of interference in the source data. This work is a part of the solution to the more general problem of developing a system for managing the maturity level of business processes in an organization. Changes in organizational maturity of a company are described in terms of a managed dynamic system. It is shown that such a model adequately reproduces a number of effects in the behavior of the system of indicators of the organizational maturity of the company. The paper uses the method of analytical design of optimal Kalman-Letov regulators (ADOR), as well as a recursive Kalman filter that estimates the state vector of a dynamic system based on incomplete and noisy data. The constructed model demonstrates plausible behavior in predicting the process of organizational maturity managing. Reproduces the effect of accelerated growth of controlled indicators defined as a priority in the model. Using the Kalman filter allows one to form a control action on the dynamics of organizational maturity indicators in such a way that the target values of maturity levels are achieved even under conditions that are significantly distorted when measuring the initial data. The proposed methodology for optimal management of the organization’s maturity level is demonstrated by the example of evaluating and forecasting the maturity level of one of the departments of a technical university.

Evaluating the performance of atomic operations on modern multicore systems
Authors: Goncharenko E A , Paznikov A A , Tabakov A V 
Published: December 2019

Abstract
In this work we analyse the efficiency of atomic operations compare-and-swap (CAS), fetch-and-add (FAA), swap (SWP), load and store on modern multicore processors. These operations implemented in hardware as processor instructions are highly demanded in multithreaded programming (design of thread locks and non-blocking data structures). In this article we study the influence of cache coherence protocol, size and locality of the data on the latency of the operations. We developed a benchmark for analyzing the dependencies of throughput and latency on these parameters. We present the results of the evaluation of the efficiency of atomic operations on modern x86-64 processors and give recommendations for the optimizations. Particularly we found atomic operations, which have minimum (load), maximum (“successful CAS”, store) and comparable (“unsuccessful CAS”, FAA, SWP) latency. We showed that the choice of a processor core to perform the operation and the state of cache-line impact on the latency at average 1.5 and 1.3 times respectively. The suboptimal choice of the parameters may increase the throughput of atomic operations from 1.1 to 7.2 times. Our evidences may be used in the design of new and optimization of existing concurrent data structures and synchronization primitives.
