11. Locally defined planning disciplines [№4 за 2013 год]
Authors: (grntl@niisi.msk.ru) - , Ph.D;
Abstract: The paper deals with systems, considering as a number of tasks, which are to be executed in a predefined period of time. Planning function points to a particular task of a system which is to be executing in a current moment. Planning discipline is a rule prescribing a specific planning function to a system. Planning function, although it is a global object, could be considered locally, i.e. it could be built based on local conditions but not the whole scope of data, describing all tasks in the past and in the future (according to a current moment). Inherited and locally defined disciplines are under consideration. The paper clarifies corresponding notions in a mathematical manor. Inherited disciplines are those which depend on system state in critical points, i.e. moments when new tasks appear. A theorem establishing coincidence of algorithmic and axiomatic definitions of inherited disciplines is formulated. Locally defined discipline prescribes to a system its planning function in a way that depends on local state of the system in an arbitrary moment of time. A theorem is formulated which determines a structure of an arbitrary locally defined discipline. The theorem states that a locally defined discipline is inherited in relation to a locally defined discipline applied to systems with a single critical point.

12. Cognitive measurements: the future of intelligent systems [№4 за 2013 год]
Authors: (maria.svyatkina@gmail.com) - , Ph.D; (tarasov@rk9.bmstu.ru) - ;
Abstract: This paper considers next generation intelligent systems based on measurements and knowledge discovery from sensor data. A comparison between measurement and expert estimation is made. Some sources and types of measurement uncertainty are elicited. Non-classical measurement concepts such as distributed measurements, intelligent measurements, soft measurements are discussed. Some fundamentals of granular measurements theory are formulated. A new concept of cognitive measurements as a hierarchical information granulation process based on the principle of «Measurement-Pragmatic Estimation» unity is proposed. A two-leveled architecture of cognitive measurements is considered. A logical-algebraic approach to data interpretation and analysis on the top level of cognitive measurements is developed. To implement cognitive measurements the notion of cognitive sensors equipped with granular pragmatics is introduced by taking multi-valued and fuzzy logics together with Peirce’s pragmatic maxima. Granular interpretations of multi-sensor data fusion are proposed. Both crisp and fuzzy logical pragmatics for individual sensors and their dyads are constructed using product lattices and bilattices.

Abstract: This paper addresses building of a system working with multi-dimensional analytic spaces used to process analytical data (OLAP-data cubes) by means of shareware, free tools and software to develop web-applications. The paper considers the issues related to development of a database structure, the encoding system and the language used to address to the multi-dimensional space, as well as building and design of a translator converting the expressions written in the language used to address to the multi-dimensional space into the language used to make database queries (SQL data-query language). Application of the approach described in this paper allows designing and building OLAP-data cubes using conventional means for web-application development without using expensive, special-purpose software to work with multi-dimensional analytic spaces (OLAP-data cubes).

15. Multiagent systems verification with markov chains: probability estimation of optimal solution finding by agents [№4 за 2013 год]
Author: (zaycev.ivan@gmail.com) - ;
Abstract: The paper presents general description of meta-algorithm, used by some class of multiagent systems. Nowadays multiagent approach for complex systems building gains more and more popularity. But the theory, connected with it, still remains not developed enough. It’s still unclear or not well-founded, which kind of systems should be used in particular cases, and what advantages these systems have. Partly it’s because multiagent systems may have different meanings in different research areas. In this work one particular class of multiagent systems is considered. Formalization of this class is connected with Markov chains, so we can estimate some properties of these systems using that mathematical instrument. Then, for systems built with some functions, statement is proved that probability of finding allowable solution by agent is higher when fitness function meaning for this solution is higher.

16. Computing cluster upgrade for simultaneous execution of Linux and MS Windows OS [№4 за 2013 год]
Author: Ermakov D.G. (Ermak@imm.uran.ru) - Institute of Mathematics and Mechanics Ural Branch of the Russian Federationn Academy of Sciences; (bay@hackerdom.ru) - ;
Abstract: The task of upgrading the software of a massively parallel supercomputer for the simultaneous execution of two different operating systems (Linux and Microsoft Windows HPC Server) at the same hardware cluster, each of them at its own node set (logical cluster) is completed. The process of installing Microsoft Windows and HPC Pack tools on cluster nodes using two DHCP servers is described. One of the features of the proposed solution is the absence of the Infiniband (Application Network) connection at the headend under Linux, which makes it necessary to use two DHCP servers. The problems revealed in the course of installing the Windows HPC Server and the Russian interface package are mentioned. The following approaches to organizing the choice of an operating system loaded to the cluster nodes are considered: the choice of the loaded system by an operator, alternation, creation of a common boot sector and choice of the loaded operating system by recording a file on this disk, and network loading with the choice of the operating system by a DHCP server. The latter approach is proved to be to most appropriate, some peculiarities of its implementation are described. The scripts that control the node switching and their functions are listed. It is mentioned that the main scripts are executed at the Linux headend. The access to these scripts from the Windows headend is provided by extending PowerShell tools by means of the SSH cmdlet set from PowerShell that uses the SSH.NET library. The proposed solution provides a quick switching of nodes between the Linux and Windows logical clusters.

Abstract: The predesign research is a strategic step in object designing process, it helps to make a decision on the level of competitiveness, assess the development prospects, the problem statement for the project, the complexity and feasibility of the system. Existing methods of predesign researches have a high degree of generality and are not formalized. They analyze the specific (single) prototypes aimed at finding out solutions to the current problems and disadvantages of a given prototype. So, there is a need to create a new cognitive technology of predesign researches to get the most complete information for this stage. The article describes the algorithm of the predesign researches and modeling of information systems. The implementation of the algorithm is required to solve the relevant scientific problem of increasing the pre-work effectiveness for information and technical systems development. The list of basic procedures is required for the pre-work for the stage of information systems conceptual design. This method will improve the efficiency of modeling process and pre-work for creation of information systems using a systematic approach for analyzing and synthesizing it.

18. Development of the software environment to support the systems functional structure analysis in the view of holistic property [№4 за 2013 год]
Authors: Butenko D.V. (butenko@vstu.ru) - Volgograd State Technical University, Ph.D; (roman.bugriy@gmail.com) - ;
Abstract: One of the fundamental systems’ attribute is a property of integrity. Description of its functional structure allows understanding that the system is very stable. The structure can be presented as binary oppositions that reflect the opposing structural relations between functional components and subsystems concepts. The main idea when building a binary opposition is the using invariant pairs of operations proposed by R. Koller in his method of design. Based on theoretical research a software system of technical systems analysis in the view of property of integrity is proposed. This system consists of three modules: constructive and functional analysis, Ishikawa diagram construction to consider a contrary-functional pairs of the system, writing a report using system expert evaluation regarding a property of integrity.

19. Basic approach to solving the creating a human-machine interface using dual principle [№4 за 2013 год]
Authors: (aminitaeva@mail.ru) - , Ph.D;
Abstract: The article describes the usability problem of ergatic management systems (ESA) as a component of the interaction between an operator, an object, environment and control systems in data-processing systems. The most important component here is the solution of creating a complex human-machine interface (HMI) problem using dual principle which maximally takes into account a human factor – psychological, physiological and anatomical aspects of human-computer interaction with the full range of functional problems solved. The research on digital computing systems with artificial intelligence becomes particularly relevant for human-machine interface and computer control. The main motivating reason for the creation of such systems is the security with its high intensity in the modern world. The development of this direction involves fundamental changes in the functional structure of the management process, the creation of the necessary theoretical basis for formulating and solving specific scientific and engineering problems. In this regard, one of the most important design issues of high ESA is the optimal distribution of functions between PR and technical means considering the psycho-physiological capacities of a human. This kind of work is based on the feasibility provided by existing automation devices and computer equipment. The novelty and prospectivity of implementation of the proposed approach is defined by the results to design and build, where a key part may be a prevention of psychological and physiological factors. The creation of a complex system using a dual principle allows implementing the urgent tasks of the human-machine interface organization considering the intellectualization of human-machine complex, construction and development of automated information management systems and diagnosing psychological and physiological security of a person.

Abstract: The article is devoted to the methodological approaches to the maturity appraisement of the software development processes according to the CMMI® model developed by the Software Engineering Institute (SEI) at Carnegie Mellon University. The article proposes and discusses the methods of quality appraisement of objective evidence and extent of implementation of practices that ensure achievement of the goals of the CMMI® process areas. Such appraisals are necessary to understand the processes maturity level of the developer. In case of uncertainty and/or information incompleteness on the implementation of CMMI® practices, it is reasonable to use a toolkit used for decision-making in weakly formalized subject domains. It helps to increase confidence in appraisal team solutions. This article considers two approaches to appraisals formation: fuzzy logic methods and multi-criteria classification methods (using the classes with fuzzy boundaries and the decision rules) with the possibility of their combining depending on the completeness of information available for the appraisal team.
Keywords: multi-criteria classification, fuzzy logic, decision theory, objective evidence, appraisement, process area, maturity levels, capability levels, cmmi
