The article reveals difficulties to make managerial decisions as to optimization of recreational objects’ location considering economic and technological parameters of an impact with application of fuzzy modelling. The authors propose methods of evaluation of alternative variants of managerial decision making applying programs of Mathcad with the further prospect of choosing alternatives.

Solution of ecological problems is an urgent and extremely important task at the present stage of social economic development of Ukraine. Unreasonably high degree of economic (mostly agricultural) reclaiming of area causes spreading and intensification of degradation processes in ecosystems. Conservation of lands, including the one carried out by means of foresting of degraded lands, is the principal way to renature environment. The article concerns an issue of land conservation in the context of ecosystem services of forests. The aim of the article is to assess the economic value of ecosystem services of forests in case of land conservation. To achieve the aim the authors developed a classification system of ecosystem services of forests according to their functional purposes; provide the calculation of prospective economic value of ecosystem services while foresting of a land plot with heavy eroded soil. The research was carried out using system, monographic and abstract-logical methods. The integral evaluation of prospective ecosystem services of forest in case of foresting of degraded land resulted in: minimum – 5. 07 thousand UAH per 1 ha in a year, maximum – 35. 91 thousand UAH per 1 ha in a year. The calculation of economic costs of ecosystem services should be applied for assessment of the economic value from protection of nature-protective areas as well as implementation of economic stimulation for land conservation.

2015
Taratula, R., Lviv National Agrarian Univ. (Ukraine) | Ryzhok, Z., Lviv National Agrarian Univ. (Ukraine)
The article describes aspects of maximum application of economic potential of land resources as an economic category for territorial organization of production. The author has analysed indicators of estimation of efficiency of economic potential of land resources on the territory of the region, where volume of gross output of agricultural production is considered a principal one.

The technological potential of agricultural enterprise is complex system consisting of various elements with different functional capabilities and features, which are characterized by the characteristics of complex systems. The complexity of technological potential lies in the presence in structure of its several elements − technological preparation of production, equipment and technology. There is no doubt that the basis of technological potential is an active part of main production assets, namely the equipment park. Working machines and equipment, instrumentation, transmission devices and tooling − this is exactly what primarily determines the level of labour productivity. The aim of the study is to develop recommendations for efficient use of machinery of agrarian enterprises as part of their technological potential, to solve important task of developing them and improving quality and competitiveness of their products. In methodological basis of this research various methods were used: an analytical method, abstract and logical method, system approach, statistical and economic analysis, method of analogies, and method of comparative and expert estimates. The study showed that in order to increase the efficiency of use of technical equipment and more fully satisfy agricultural producers in technical services, it is necessary to create the technical centre for maintenance and repair of agricultural machines. As result, implementation of preventive strategy of technical maintenance and repair of equipment will reduce the number of machine failures by 2−2.5 times, increase the use of resource of their components and mechanisms by 30%, and significantly reduce the loss of agricultural products due to long downtime of mechanization equipment and crop shortages while increasing agro-technical timelines for field work.
