Knowledge Discovery in Dynamic Data Using Neural Networks

Abstract. The main aim of this paper is to provide basic knowledge background for further work. The basis is classification of available methods for multi-criterial evaluation. This classification will serve as a support of project (Comparison of methods of multi-criteria evaluation with user ratings of ITIL tools). In first part of this paper are described different approaches to multi-criterial evaluation and decision-making. Second part presents basics of methods of determining criteria strength and mainly their classification and division into categories.

“…Modelling undertaken on the gradually developed model M -by suitable programming language on PC -allows to create by a new method of simulation modelling ( Fig.2 and Fig.3) adaptable model of system S. The creation of the model M in purpose-defined environments and modelling environments is generally described in numerous publications and articles [1], [7] which is filled with erudite view amidst into a broader philosophical, psycho-social, economic and educational contexts embedded in European and world context with effectively linked control variables related mainly to social environment [2], [8] Modern possibilities of advanced artificial intelligence methods in integrative environment of cybernetics, [5], [6] describes the modern means of technical cybernetics and their modelling for system integration [3], [10] in the cyber environment [4], [9].…”

Possibilities of identifying cyber attack in noisy space of n-dimensional abstract system

et al. 2016

Abstract. This article briefly mentions some selected options of current concept for identifying cyber attacks from the perspective of the new cyberspace of real system. In the cyberspace, there is defined n-dimensional abstract system containing elements of the spatial arrangement of partial system elements such as micro-environment of cyber systems surrounded by other suitably arranged corresponding noise space. This space is also gradually supplemented by a new image of dynamic processes in a discreet environment, and corresponding again to n-dimensional expression of time space defining existence and also the prediction for expected cyber attacksin the noise space. Noises are seen here as useful and necessary for modern information and communication technologies (e.g. in processes of applied cryptography in ICT) and then the so-called useless noises designed for initial (necessary) filtering of this highly aggressive environment and in future expectedly offensive background in cyber war (e.g. the destruction of unmanned means of an electromagnetic pulse, or for destruction of new safety barriers created on principles of electrostatic field or on other principles of modern physics, etc.).The key to these new options is the expression of abstract systems based on the models of microelements of cyber systems and their hierarchical concept in structure of n-dimensional system in given cyberspace. The aim of this article is to highlight the possible systemic expression of cyberspace of abstract system and possible identification in time-spatial expression of real environment (on microelements of cyber systems and their surroundings with noise characteristics and time dimension in dynamic of microelements' own time and externaltime defined by real environment). The article was based on a partial task of faculty specific research.

“…One of the basic cybernetic approaches exploring, analyzing, designing and planning systems are in modeling and models. Modeling is an essential element model [1,3]. The modeling and simulation is the technical term model is applied to the analogy between two systems (Fig.…”

et al. 2016

Abstract. The paper deals with the applications of modeling and simulation tools in the optimization of business processes, especially in solving an optimization of signal flow in security company. As a modeling tool was selected Simul8 software that is used to process modeling based on discrete event simulation and which enables the creation of a visual model of production and distribution processes.
