The paper addresses the relevant issue of ensuring the reliability of solving large scientific and applied problems in computing environments that integrate Grid and cloud computing. The main reliability parameter is the probability of successful problem-solving in a computing environment with the following specified quality criteria: efficiency of the allocated resources use, and time, deadline or cost of executing jobs. We propose a new technology for testing and evaluating the reliability of functioning of problem-oriented heterogeneous distributed computing environments. It integrates models, representing different layers of knowledge about the environments, and special tools that automate a study of these environments. Applying such technology provides an increase in the reliability and efficiency of heterogeneous distributed computing environments by parametric adjusting of local resources managers installed in the environment nodes. Their adjustment is implemented on the base of the results of testing and evaluating obtained with the use of complex (conceptual, simulation, and semi-natural) modeling and meta-monitoring of computational resources.

We introduce the discrete automaton models of gene networks with weight functions of vertices accounting for the various forms of the regulatory interaction of agents. We study the discrete mapping that describes the operation of a fragment of the gene network of the bacteria E. coli. For this mapping, we find its fixed points (stationary states) on using the SAT approach. We also study the mappings that are defined by the random graphs of the network which we generate in accordance with the Gilbert-Erdos-Renyi and Watts-Strogatz models. For these mappings, we find the fixed points and the length 2 and 3 cycles. This article can be regarded as a survey of our results on the discrete models of gene networks and the numerical methods for studying their operation. © 2014 Pleiades Publishing, Ltd.

Approximate solution to the resource consumption minimization problem. I. Construction of a quasioptimal control

Journal of Applied and Industrial Mathematics 2011年第4期5卷 467-477页

For linear systems with constrained control and fixed transition time, we propose two methods for solving the resource consumption minimization problem approximately. We prove that the switching moments of resource-quasioptimal controls are independent of the initial conditions and constant for autonomous systems. Some region of the initial conditions is found for which the constraints on the control are never violated. © 2011 Pleiades Publishing, Ltd.

In this paper we present a hybrid approach to integrative clustering based on the p-median problem with clients' preferences. We formulate the problem of simultaneous clustering of a set of objects, characterized by two sets of features, as a bi-level p-median model. An exact approach involving a branch-and-cut method combined with the simulated annealing algorithm is used, that allows one to find a two-source clustering. The proposed approach is compared with some well-known mathematical optimisation based clustering techniques applied to the NCI-60 tumour cell line anticancer drug screen dataset. The results obtained demonstrate the applicability of our approach to find competitive integrative clusterings. Copyright © by the paper's authors.

Nowadays, the problem of automating the software delivery processes and resource configuring in computing environments with parallel and distributed architectures to ensure the functioning of digital twins is highly relevant. A large spectrum of the well-known tools for software configuration management is available. However, most of them do not solve problems emerging in the considered subject domain fully. To this end, we propose a new framework for implementing preparing, debugging, delivering, testing, deploying, and configuring virtualized software of digital twins. Currently, we are developing such twins for analyzing the operation of environmentally friendly equipment of infrastructural objects located in the Baikal natural territory. The proposed framework is based on the integrated applying methods and tools of knowledge engineering, multi-agent technologies, conceptual and service-oriented programming, and administration of hybrid distributed computing systems. These systems can include both personal resources and resources of public access centers, grid systems, and cloud or fog platforms. We carried out the practical experiments with the framework prototype. The obtained results have shown that significant speedup in performing the aforementioned processes can be achieved.

The paper is devoted to discovering new features of diagonal Latin squares of small order. We present an algorithm, based on a special kind of transformations, that constructs a canonical form of a given diagonal Latin square. Each canonical form corresponds to one isotopy class of diagonal Latin squares. The algorithm was implemented and used to enumerate the isotopy classes of diagonal Latin squares of order at most 8. For order 8 the computational experiment was conducted in a volunteer computing project. The algorithm was also used to estimate how long it would take to enumerate the isotopy classes of diagonal Latin squares of order 9 in the same volunteer computing project. © 2019, Springer Nature Switzerland AG.

Design and study of mathematical models of marshalling yards in order to increase productivity and ensure their smooth operation is relevant, since these objects are key elements for the organization of freight transport on the railway network. In this work, we develop a mathematical model for the operation of a marshalling yard in the form of a four-phase queuing system with BMAP flow and group service of requests. Each phase is a non-Markov multichannel queuing system with a finite queue and group service of requests in the channel. For its numerical study, we create and implement a simulation model. The proposed mathematical apparatus and software are tested on for the operating marshalling yard, which is typical and located on the East Siberian Railway. We demonstrate that it allows us to assess the current level of operation, determine the maximum permissible load and find bottlenecks in the structure of the selected station and then eliminate them. © 2021, Springer Nature Switzerland AG.

This article presents a package for analyzing the energy system vulnerability developed with new technology for continuous integration, delivery, and deployment of applied software. It implements a framework that allows combining and optimally using various methods for modelling energy systems and provides the comprehensive assessment of their vulnerability with regard to various uncertainties. The essential principles to identify and rank critical elements of an energy system are considered in the article. The investigations made with the package shown that the principles seem to be logical for the subsequent construction of the invariant set of measures for improving the energy system resilience. © The Authors, published by EDP Sciences, 2020.

Bridging network static properties and activation dynamics

Procedia Computer Science 2017年 119卷 157-165页

作者： Stepan Kochemazov Matrosov Institute for System Dynamics and Control Theory of the Siberian Branch of the RAS Lermontov str. 134 664033 Irkutsk Russia

The paper studies a variant of Granovetter’s threshold model of conforming behavior. In this model, a network of agents with binary states (inactive/active) acts in discrete time under the influence of instigators (always active agents). Using special computational method based on algorithms for solving Boolean satisfiability problem, we can find dispositions of small number of instigators among initially inactive agents, which after several time moments force the majority of agents to the active state. Using a large number of networks, both randomly generated, and fragments of real world social networks, we search for the interconnection between static and dynamic characteristics of network vertices: whether or not static centrality measures influence the chances of the vertex to be picked as an instigator.

The paper deals with techniques of constructing optimal control problems and testing optimization software for controlled dynamical systems. A test collection of nonconvex optimal control problems has been developed and used for studying the properties of optimization software. The description of the collection problems is made using the generated template, which includes the formulation of the problem statement, characteristics of the computational process and the obtained results, containing graphical visualizations of the reachable set and optimal controls with corresponding trajectories. Several testing techniques based on presented collection are proposed.
