The article is devoted to the development and improvement of methodology and implementation of riskcontrolling subsystem in the management system of oil and gas companies in under uncertainty conditions. It is proved, that the mathematical tool of Fuzzy Logic allows to reveal and take into account complicated nonlinear dependences between quantitative and qualitative indicators of risk-event probability estimation, and also mutual effect of risk forming factors. The six-level system of evaluation of risks of operating activities of oil and gas companies, based on fuzzy logic has been established. It allows to take into account the non-linear nature of the relationship between the risk forming factors and the resulting indicator. The logical inference model has been designed. It shows the dependence of the risk level on the meaning of linguistic rules about groups of risk forming factors in different risk groups and which is the basis for the risk assessment model. The conceptual model of management of oil and gas companies with the risk-controlling subsystem as a part of it, the main element of which is the fuzzy model of risk assessment and forecasting, has been proposed. The research concluded, that the implementation of the proposed model of management of oil and gas production enterprises will significantly improve the efficiency of the upstream segment enterprises and significantly reduce losses, caused by the occurrence of risk-events. Keywords—controlling, risk, risk-controlling, risk assessment, fuzzy logic, risk-controlling subsystem, oil and gas company, management system

In market conditions, competition is the main mechanism for regulating economic relations. It poses the problem of ensuring the survival and the possibility of further development of enterprises, which requires the participants of the economic process to take adequate measures to improve the mechanism, forms and methods of management. In these circumstances, it is especially relevant to study the issues of formation, operation, reproduction and management of capital of enterprises, and especially its working part. Working capital is a compulsory element of production that provides all the current activities of business entities. The article deals with the etymology and concept of capital, as well as its component current capital. It is proved that in order to increase the efficiency of the process of managing the current capital of the enterprise, it is important to find the optimal ratio of its components. In such circumstances, the process of optimization becomes a feature of the current capital management strategy. It is established that the most relevant to the optimization process will be a moderate strategy of system-oriented current capital management. On this basis, optimization covers the study of patterns and relationships between all components of current capital. In order to study these relationships, it is necessary to determine the impact on each component of the rest of the current capital components. These relationships are cyclical, and we find that their descriptions are appropriate using mathematical models. Accordingly, models for optimizing the size of the basic elements of current capital using the Lotka-Volterra equation have been developed. It has been proved that such model allows to estimate the level of mutual influence between components of current capital and to carry out the analysis with the purpose of making effective management decisions. In addition, in order to obtain adequate data on the behaviour of current capital components, it is appropriate in the future to determine the factors influencing them and the magnitude of the weighting factors that will correspond to them. These coefficients were determined using the method of expert estimation using the technique of point estimation. It has been established that the determination of the maximum and minimum levels of values for the components of current capital has a significant impact on the process of system-oriented management, and the factors that influence these levels will be represented by the indicators that are characterized by the following parameters. In the simulation process it has been found that the most important element, on which the managers of the enterprise in the decision-making process regarding current capital should focus, is the value of stocks taking into account their maximum allowable level.

Topicality. Globalization is characterized by exponential rates of production of goods and services, extraction of natural resources, increase in energy consumption. This has led to climate change. As a result, it is necessary to find a solution to this problem in order to reduce the negative impact of humanity on the environment. One such solution is the production of bioenergy. Ukraine is still an agro-industrial country, and it has a high bioenergy potential. In recent years (2013-2018) bioenergy of Ukraine has started to develop, but the existing pace of development is not enough to achieve the goals set out in the main plan of the article. Potential bioenergy producers claim that there is no economic benefit from such activities. Therefore, this statement is analyzed and refuted. The paper evaluates the bioenergy potential of Ukraine, proves the economic effect of bioenergy production, forecasts the development of this sector, analyzes the impact of subsidizing natural gas consumers on the development of the bioenergy sector. The paper assessed the bioenergy potential of Ukraine in comparison with other countries, took into account the participation of Ukraine in international programs, forecast the development of the domestic bioenergy market. The study revealed that activities in the field of bioenergy has an economic and investment effect. Keywords—bioenergy, economic evaluation, subsidizing, «green» tariffs, biowaste.

The use of inventory management models enables the management of the company to optimize logistics business processes and to reduce fixed and variable costs of production, order and sales. The study proposes a multinomenclature model for optimizing inventory business processes using asymptotic methods. An easy-to-use analytical formula for determining optimal order interval, when order and inventory holding costs meet insufficient cyclical changes, is obtained. Testing of the developed model of optimization of inventory business processes was carried out on the example of the enterprise operating in the HoReCa segment of Zaporizhzhia the regional market. The proposed multinomenclature inventory management model enables the company management to apply situational management of these processes, modeling the changes caused by increased product storage costs and order fulfillment.

The purpose of the article is to substantiate the approach to selecting the depreciation method in oil and gas companies. To achieve this purpose, the following research methods were used: observation, comparison, integrated study of business transactions – to collect factual information on the use of depreciation methods in oil and gas companies; abstraction, analysis – to substantiate the approach to selecting the depreciation method for property, plant, and equipment; graphical method – for the visual presentation of research material. The scientific novelty of the study is that the authors have substantiated the approach to selecting the depreciation method for property, plant, and equipment in oil and gas companies. In order to optimally select the depreciation method the authors have proposed to develop a testing system with the help of the automated accounting system. It will test property, plant, and equipment within different groups, in particular in terms of the anticipated revenues, nature of assets use, etc. This will help to improve the qualitative characteristics of financial statements in terms of the reliability of information about property, plant, and equipment. Keywords—property, plant, and equipment, depreciation methods, financial statements, oil and gas companies.

The impact of industrial waste and enterprises’ emissions on the chemical composition of water, in particular, the content of phosphate ions in it and the main physicochemical indicators of water (dissolved oxygen, hydrogen index and water temperature) are determined. A model for assessing the level of multipurpose water use and protection using tools of economic-mathematical modeling – fuzzy set theory implemented in MATLAB software is developed. Factors of this model include level of production improvement, adherence to technological discipline; level of average content of phosphate concentration and physicochemical parameters of the water; full disposal of household, agricultural and industrial waste; rationing of water supply and drainage, rationing of maximum permissible concentration of various substances in the waters for drinking, fishery and other purposes; zero waste water discharge, recirculating water supply; imposing penalties on pollution, littering and water depletion up to the closure of enterprises, factories workshops, complexes-pollutants in accordance with the legislation in force; phytomelioration; subsoil tillage, contour farming. Terms for the linguistic assessment of selected factors of the level of multipurpose water use and protection in hydroecosystems based on fuzzy logic theory and the ranges of their changes are proposed. The rules base for the developed model is formed. Input and output parameters defuzzification is carried out according to the “center of gravity” of the Mamdani module of the MATLAB software. The level of multipurpose water use and protection is recorded at 80%, which corresponds to the high level (from 70% to 100%) of the scale and can be improved by increasing the level of each factor of the model. It is established that, when supplementing the input parameters and the rule base, the developed model can be applied to specific industrial enterprises.
