THE STUDY OF THE TEMPORAL CHARACTERISTICS OF THE SRP SYNCHRONIZATION METHOD FOR COMMUNICATION SYSTEMS FOR MILITARY AND CIVIL PURPOSES ON THE BASIS OF MCDS-CDMA

abstract 1131509015 issue 113 pp. 184 – 195 30.11.2015 ru 577
The goal of the study is to research time characteristics of pseudo-noise sequence acquisition method for multicarrier communication systems of MC-DSCDMA, that allows low hardware requirements and able to operate in low quality channels. The way of achieving this lies in using a mathematical model of algorithm. The achieved results show suitability of MC-DS-CDMA-signals optimization for pseudo-noise sequence acquisition efficiency increase. The achieved results can be applied in MC-DS-CDMA communication systems development

THE TECHNIQUE AND THE MODEL OF THE RISKS ASSESSMENT OF MACRO ENVIRONMENT OF THE AGROINDUSTRIAL INTEGRATED PRODUCTION SYSTEM ON THE BASIS OF THE INTEGRATED INDICATOR

abstract 1231609099 issue 123 pp. 1454 – 1471 30.11.2016 ru 237
The analysis and assessment of risk at the macrolevel in this context is understood as assessment of extent of influence of the external environment (macro environment) on activity of the integrated production system. In the article the model and the technique of calculation of an integrated indicator of risk of an adverse effect of the external environment of the agro-industrial integrated production system is offered. All stages of creation of the model which include representation of basic risk factors of macrolevel in the form of linguistic variables are described, each of basic risk factors is a compound linguistic variable. For obtaining total value of a basic factor the matrix scheme of aggregation of compound factors to basic level is used. The equation of model of an integrated indicator of risk of an adverse effect of the external environment on the integrated production system is presented. The principle of recognition and interpretation of result on the basis of standard fuzzy 01-classificators is shown. Also in this article the interrelation of an integrated indicator with the choice of the strategy of development for business system by definition of a condition of the external environment is shown, and depending on it the strategic scenario of development of business system is offered

USE OF TRIANGULAR INDISTINCT NUMBERS FOR SIZE OF MATERIAL STREAM IN BREAD-PRODUCTION CHAIN FORECASTING

abstract 0591005021 issue 59 pp. 334 – 344 31.05.2010 ru 2399
In this article the size of material stream in bread-production chain with use of the theory of indistinct sets and application of risk component is predicted, the interval model of definition of efficiency is developed
