Reproduction of causal networks on the basis of Markov properties analysis /
O.S. Balabanov // Mathematical Machines and Systems. – 2016. – N 1. – P. 16 – 26.
We characterize an independence-based approach to causal model inference from data. In contrast to regression, methods of this approach are aimed to asymptotically correctly recover a generative model. The merit of independence-based methods is inherent decomposition of model inference. This results in reducing dimensionality of statistics used as well as problem hardness. Aiming to enhance efficiency of methods we devise a few resolutions which facilitate contraction a space of search for separator and reducing a hardness of edge verification. The resolutions are grounded on necessary requirements on a member of locally-minimal d-separator. Efficiency of methods developed is demonstrated via few examples. Principles for verification of method effectiveness and model adequacy are presented. Таbl.: 1. Figs.: 4. Refs.: 24 titles.

Organization of Advanced ISR Systems by High-Level Networking Technology /
P.S. Sapaty // Mathematical Machines and Systems. – 2016. – N 1. – P. 27 – 38.
With the world dynamics growing rapidly in the ХХІ st century, advanced Intelligence, Surveillance and Reconnaissance (ISR) systems are becoming of paramount significance to predict, analyze and withstand unexpected situations and conflicts. ISR is also the most important component of military systems for planning and management of operations of any complexity and coverage. The paper discusses organization of large distributed ISR systems based on a high-level networking technology effectively converting the distributed world into a parallel spatial supercomputer. The latter allows us to quickly present concise knowledge on the problems occurred instead of a huge amount of raw data which is difficult to analyze and generalize by conventional means. This material has been partially reported at recent international ISR and Night Vision conferences in London, United Kingdom. Figs.: 15. Refs.: 18 titles.

Simulation the process of ranking of alternatives of hierarchies analysis method by means of constructive and productive structures / V.I. Shynkarenko, T.M. Vasetska // Mathematical Machines and Systems. – 2016. – N 1. – P. 39 – 47.
The formalization of the constructive process of ranking of alternatives for decision making by the classical method of hierarchies analysis is made. The method of constructive and productive structures is used for formalization. All the elements of the process, the connections between them, and its constructive features are selected in the process of formalization. The proposed formalization allows modifying and improving the process of ranking with unchanged basis of the analytic hierarchy process. Refs.: 15 titles.

The article presents the results of research in population dynamics of Lepus europaeus Pall depending on weather and climatic factors in the national park “Vyzhnytsky” during the period of 2002–2013 years with the help of monitoring information system. Our analysis provides evidence in favor of a negative relationship between population dynamics of studied population of Lepus europaeus Pall and maximum temperature in September. At the same time, increased rainfall in September, has a positive effect on the number of Lepus europaeus Pall. population during the study period within the territory of national park. Таbl.: 2.

Formation of rescue equipment is an actual task of multicriteria optimization, which is solved in terms of financial and resource shortages. An evolutionary method of the optimum set of such equipment determination is proposed in the paper. Since this method is parametric, thus the basic aspects of potential solutions formation based on the principle of protectionism are suggested. Refs.: 7 titles.
