Zoning of territories is one of the mechanisms of real estate management. Economic analysis of real estate includes consideration of the problems of spatial – economic development of real estate which exists in specially organized space. Difference in land value, expressed through economic parameters of real estate, forms the basis of territorial – economic zoning, definition of cost equivalent of real estate objects. Global practice shows, that it is increase of land value as a result of zonal-territorial policy realization that leads to the maximal economic benefit. Only joint influence on real estate objects and their spatial environment сan provide the best social and economic results.

To the East Donbass agglomeration has developed thematic maps of subsiding soils, indicating their capacity, groundwater levels, surface subsidence above mining, landslide and erosion hazards. Sources of information were the materials of the geological surveys, maps and literature data, and numerical modeling. For the purposes of industrial and civil construction built the final map of the cumulative effects of geological hazards.

Personnel motivation strategy is a part of a strategy of the whole company. It is long-term plan of particular actions, which has an aim to develop personnel’s potential to the full extent. As an impact, this allows the company to have a competitive advantage in strategy.
There are a few main approaches to strategy development and, as a consequence, a few options of personnel motivation strategy.
When it comes to development of personnel motivation strategy, there are several stages that shall be competed, as follows: diagnostics of current personnel motivation strategy; development of main strategies, aims and principles of company’s motivation policy, as well as its content and structure; development of employees’ material monetary and noncash remuneration, and non-financial reward; development of internal white papers in order to establish personnel motivation strategy; implementation and effect monitoring of established personnel motivation strategy.
Keywords: personnel motivation, motivation strategy, material remuneration, non-financial remuneration, effectiveness of personnel motivation.

Consensus problem involves a system of processes, some of which may be faulty. A fundamental problem of fault-tolerant distributed computing is for the reliable processes to reach a agreement on a same decision. One approach to achieving such agreement is for processes to vote and agree on the majority value. In the absence of faults, this works fine, but the vote even one faulty process can swing the outcome. In this paper we present some result of analysis of a mixed-failure model, where t processes may fail, b out of which is the Byzantine failures and remaining c is crash processes. In a asynchronous model of computation for several distributed problems it turns out that a collection of N processes can tolerate c crash failures if 2c < N, while robustness against b Byzantine failures requires 3b < N. Our algorithm rely on a weak definition of the Byzantine failures which disallows them act as a dead or a crash processes and can tolerate the 2(N – 2c)/3 failures.

The results of the heat transfer processes studies in the heat exchange borehole (BHE), equipped with coaxial collector in order to establish the influence of its design parameters, the properties of the rock mass, mode and duration of the coolant flow to the effective temperature difference. The resulting analytical equation for the effective temperature difference in the conditions of unsteady heat transfer experimentally verified in a lab BHE and can be used in the design of these BHE systems in specific geological and technical conditions. Use the resulting equation for the inverse calculation can be counted the diameter and the depth of the BHE, as well as the duration of the coolant circulation in the coaxial collector.
