COGNITIVE MODELS OF PREDICTION THE DEVELOPMENT OF A DIVERSIFIED CORPORATION
DescriptionThe application of classical forecasting methods applied to a diversified corporation faces some certain difficulties, due to its economic nature. Unlike other businesses, diversified corporations are characterized by multidimensional arrays of data with a high degree of distortion and fragmentation of information due to the cumulative effect of the incompleteness and distortion of accounting information from the enterprises in it. Under these conditions, the applied methods and tools must have high resolution and work effectively with large databases with incomplete information, ensure the correct common comparable quantitative processing of the heterogeneous nature of the factors measured in different units. It is therefore necessary to select or develop some methods that can work with complex poorly formalized tasks. This fact substantiates the relevance of the problem of developing models, methods and tools for solving the problem of forecasting the development of diversified corporations. This is the subject of this work, which makes it relevant. The work aims to: 1) analyze the forecasting methods to justify the choice of system-cognitive analysis as one of the effective methods for the prediction of semi-structured tasks; 2) to adapt and develop the method of systemic-cognitive analysis for forecasting of dynamics of development of the corporation subject to the scenario approach; 3) to develop predictive model scenarios of changes in basic economic indicators of development of the corporation and to assess their credibility; 4) determine the analytical form of the dependence between past and future scenarios of various economic indicators; 5) develop analytical models weighing predictable scenarios, taking into account all prediction results with positive levels of similarity, to increase the level of reliability of forecasts; 6) to develop a calculation procedure to assess the strength of influence on the corporation (sensitivity) of its member enterprises; 7) to finalize the software tools the ask analysis to the level of information technology, given its adaptation and development to predict actions in a diversified corporation

TO THE QUESTION OF PHENOLOGY OF СONVALLARIA MAJALIS L. IN THE CONDITIONS OF THE MIDDLE DON
DescriptionFor the conservation of biodiversity, this study of patterns of biological processes and phases in the development of Convallaria majalis L. that are repeated annually becomes actual. In the article, we have presented an analysis of five years of observations of the rhythm of the development of Convallaria majalis L. in the conditions of the middle Don. There were allocated phenological phases of lily of the valley: vegetative (beginning of sprout growth, deploying of leaves), bud formation, flowering (disclosure of the first flower, mass blossoming, the withering of separate flowers, the ending of flowering), fruitage (the beginning of fruit setting, mass of fruit setting, mass ripening of fruits), the end of the vegetation (appearance of the first changes in color of leaves, the complete drying). We have defined daily average temperature and the appropriate amount of positive temperatures for the passage of various phases of development Convallaria majalis L. By the results of two growing seasons, the optimal daily average temperature for the flowering period is 14,3 ° C (the sum of average daily temperatures 161,3-204, 0С) - until 9-15 days. At higher daily air temperatures flowering begins at lower amount of positive and effective temperatures after 40-45 days after the start of the vegetation. At lower daily air temperatures flowering is longer than at higher. In the conditions of the middle Don there were allocated some examples of Convallaria majalis L. which bloom two years in a row

Description
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product, is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortagecovered by imports.According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing multicriteria economic-mathematical model of a comprehensive assessment of technology of cultivation of agricultural crops.

INVESTIGATION OF NOISE AND VIBRATION OF CUTTING CIRCULAR SAWS
DescriptionThe article presents the results of theoretical studies of noise cutting circular sawing machines. Practical calculation of the noise spectra is based on the determination of the dependency of the sound pressure of the noise sources of the object of study. In the sound system, circular sawing machines sound energy is emitted by the following sources: disc cutter and the mandrel. Therefore, the dominant noise sources should be allocated to the technological subsystem "tool – mandrel” with a bit less rigidity than the carrier system of the machine and directly receives the cutting forces when milling. Thus, it is possible to reduce sound pressure levels in almost two ways: by increasing absorption production facilities and (or) decrease in sound pressure of the noise source. In this work, we have justified the second way – reduction of the intensity of acoustic radiation of the source

THE PROBLEM OF RESEARCH OF FINAL RANKING FOR GROUP OF EXPERTS BY MEANS OF KEMENY MEDIAN
01.00.00 Physical-mathematical sciences
DescriptionIn various applications, it is necessary to analyze several expert orderings, i.e. clustered rankings objects of examination. These areas include technical studies, ecology, management, economics, sociology, forecasting, etc. The objects can be some samples of products, technologies, mathematical models, projects, job applicants and others. In the construction of the final opinion of the commission of experts, it is important to find clustered ranking that averages responses of experts. This article describes a number of methods for clustered rankings averaging, among which there is the method of Kemeny median calculation, based on the use of Kemeny distance. This article focuses on the computing side of the final ranking among the expert opinions problem by means of median Kemeny calculation. There are currently no exact algorithms for finding the set of all Kemeny medians for a given number of permutations (rankings without connections), only exhaustive search. However, there are various approaches to search for a part or all medians, which are analyzed in this study. Zhikharev's heuristic algorithms serve as a good tool to study the set of all Kemeny medians: identifying any connections in mutual locations of the medians in relation to the aggregated expert opinions set (a variety of expert answers permutations). Litvak offers one precise and one heuristic approaches to calculate the median among all possible sets of solutions. This article introduces the necessary concepts, analyzes the advantages of median Kemeny among other possible searches of expert orderings. It identifies the comparative strengths and weaknesses of examined computational ways
