The Analysis of Inexactly Specified Functions by Interval-differential Calculus

The existing approaches to system optimization under uncertainty are considered. The problem of calculating and analyzing the dynamics of function which specified up to interval. To solve this problem it is reduced to the corresponding problems for the upper and lower boundary functions of the original function. We use the technique of interval mathematics and interval-differential calculus.

Fuzzy Diferential Equations in Control. Part I

Presents the basic definitions and the theory of fuzzy sets they are further used to describe the theory of fuzzy ordinary differential equations and methods of solving them. For this, we define the membership function as an analogue of the characteristic function of the set theory. Listed species of fuzzy numbers: triangular, generalized, strong, weak, single and identifies the fuzzy vector function; function of several variables; dimensional function. Provides definitions of fuzzy arithmetic operations, as a special type of fuzzy function with its geometric interpretation. Determination of order relations which allow to compare the fuzzy numbers. We introduce the Banach space of fuzzy variables with different metrics. This allows you to define different types of fuzzy derivatives by type of convergence in these metrics. Establish the equivalence of the considered fuzzy derivatives by the wording of the corresponding theorems without proof. And provide examples of calculating the fuzzy derivative for a given fuzzy function.

Hierarchical System of Mathematical Models of Heat Conduction in Composite Materials

Within hierarchical approach the multilevel system of mathematical models of the composite material describing heat transfer and thermal interaction between a matrix of a composite and reinforcing inclusions is constructed. This system is used for the comparative analysis of estimates of effective coefficient of heat conductivity — one of the key parameters defining scope of the concrete composite. On the basis of the dual formulation of a variation problem of stationary heat conductivity in a non-uniform solid body bilateral estimates of possible values of this coefficient are received. These estimates are specified by means of Hashin — Shtrikmana's variation principle. The system of models is constructed in relation to dispersion strengthened composites with spherical inclusions. Mathematical models of heat transfer in a composite with the matrix structure, allowing to consider a relative positioning of inclusions, are considered. The bilateral estimates received on the basis of these models, limit narrower strip of possible values of effective coefficient of thermal conductivity of a composite in comparison with the specified bilateral estimates which follow from Hashin-Shtrikman's variation principle. Comparison of results of the quantitative analysis of the constructed merarkhichesky system of mathematical models allowed to draw conclusions on degree of adequacy of the constructed models.
Keywords: hierarchical approach, mathematical model, composite, spherical inclusions, effective coefficient of thermal conductivity

The Computer Simulation of the Dynamics of the Length and Weight of Fish (on the Example of South Odnoperogo of Atka Mackerel Pleurogrammus Azonus)

Based on the analysis of the sampling distribution length and weight of fish developed numerical models of their dynamics, which take into consideration the limited phase space (limb lifetime limit length and weight) and relies on the functional relationship between the length and weight of individuals, stages of their life cycle and the impact of seasonal factors. To estimate parameters, we performed a series of computational experiments. It is shown that the dynamics of the length is determined by the 18-month harmonic component, and the dynamics of weight — 12-month and 18-month components. Performed substantive interpretation of the results.
Keywords: sampling distribution, the numerical model, the task of finding the minimum, the adequacy of the model

Estimation of the Telecommunication Services Quality on the Base of the Fuzzy Modeling Method

At the present stage of development of telecommunication and wireless communications technologies improving the quality of telecom services is most nagging problem. Telecom services is constantly being improved by increasing the speed of data transmission, greater mobility of users, expanding the range of services, improving the utilization of radio frequency spectrum and the degree of network equipment intellectuality and subscriber gadgets. At the same time, improving the telecommunication links occurs at the junction of contradiction between the evergrowing consumer demand for subscription services and the limited number of frequencies that is completely objective. In turn, this causes a significant expansion of the range of services provided by the Capcom, increasing consumer demands for services quality and, as a result, improvement of existing control technologies. The main goal is the creation of the intelligent system of quality assessment and control of telecommunication services on the base of fuzzy inference system.
An approach to generation of modular intellectual system of the estimation of the telecommunication services qualities based on application of the fuzzy logical conclusion method is offered. The basic fuzzy estimation model offered within this approach in a necessary measure considers recommendations of the International Telecommunication Union in the part concerning functioning of networks of package switching on the base of the IP-protocol.
Developed system of quality assessment and control of telecommunication services is able to control the consolidated level of subjective satisfaction of users of telecommunications services through the correction of the network parameters and, thus, ensure effective decision making to increase the customer base. In the future, this system is able to operate in off-line mode, as during its development and adaptation it is not necessary to use heuristic knowledge and involve an expensive expert knowledge.

Features of Models of Geodata and Methods of their Processing in Aspect of Maintenance Semantic Geointeroperability

The Key problem of maintenance of semantic geointeroperability is creation of uniform conceptual model of representation of geodata on the basis of integration of the spatially-distributed information. Such model should be create on the basis of existing metaschemes of bases of geodata with the account multyfactority interactions of users and semantics which has been put in pawn in spatial ontologyes and-or geothesauruses and qualifiers. Work is devoted research and the analysis of existing models and methods of representation of geodata and has for an object an estimation of relevance of existing structures geogiven to methods and approaches of maintenance of their semantic geointeroperability at the decision of problems of conceptual search of geodata. For the analysis those structures of geodata which combine in itself means of display of all three groups of the spatially-distributed information have been chosen: semantic, metric and topological. Various levels of representation of a geoinformation content which demand essentially various methods of processing are considered.
