The paper presents a decision-making method for a quantitative income estimation depending on the intensity of the future tourist flow, as a complex indicator reflecting the level of the tourist market in a region or in a separate object (a hotel complex, sanatorium, tourist base, etc.). The authors proposed to use a three-level economic and mathematical model as a practical implementation of the hotel complex room stock management process. Each its level corresponds to a specific task. At the first level it is a pre-forecast study, substantiation and selection of forecasting models. At the second it is a forecast model and the quantitative value of the predicted indicator. At the third level it is a model tohelp a decision maker (DM) with decision making, i.e., a decision tree is applied as a tool. Thus, the authors present a complete system of models and methods of decision support. The results of pre-forecast analysis, development of predictive models, building, adaptation and implementation of top-level economic and mathematical models will help decision makers to make effective management decisions. There by the maneuver material resources, choose sales technologies and search for economic solutions, including in tourism recreational production activities.

Introduction. The paper presents the thesis about the advantages of the process approach in the development of measures aimed at improving the efficiency of rubber products, using rubber-containing waste as raw materials. In addition, the insufficiency of existing approaches to the definition of business processes using typical raw materials, on the basis of which the author’s definition of the business process is proposed, is substantiated. The main approaches to improving the efficiency of such business processes is formulated, defined on the construction of the participants’ interaction system to meet their basic requirements. Moreover, the importance of studying the information space is highlighted, in which the formation of business processes is displayed.Materials and methods. The research of the influence of information space on the formation of business processes for the production of rubber is carried out on the basis of such methods as the analysis of industry statistics, the study of legal acts that determine various aspects of the functioning of production and economic systems. The determination of the current state of the information space requires the research of materials of the state statistics service, marketing agencies and large enterprises of the rubber industry, using worn rubber products as raw materials. The requirements of suppliers of raw materials are also determined by an expert survey.Results. As a result, the list of the main participants and the main requirements are identified. The authors show the significant impact of the resource factor on the efficiency of business processes for the rubber production. Therefore, The authors present the model of the participants’  interaction at the stage of collecting raw materials.Discussion and conclusions. The list of the main factors hindering the development of the rubber products production is determined and ways to overcome the negative impact of factors by reviewing the mechanism of the business processes formation are considered.

Management and increasing of innovative activity of enterprise in current conditions is one of the most important part of management activity. Implementation of new technologies, optimization of costs, entering to the new markets, launching of new production , and many othersall of it should be considered when forming of strategy and plan of an enterprise activity, both on short-term and on long-term prospective. One of the post demanded innovative directions is the use of renewable sources of energy. To the most popular energy sources are refered solar panels, which can be installed on the existing constructions. Reason for development of this direction is the permanent growth of electricity, received from traditional sources, and, as the results, permanent growth of electricity cost for enterprise, and growth of prices of goods for final consumer. In this Master thesis will be considered the opportunity of implementation of renewable energy sources on existing agricultural enterprises. As subjected enterprises will be considered APC "Bolshevik" of Moskalensky district of Omsk region of Russian Federation, and "Company B" LDA of Bragança Municipality of Portuguese Rebuplic. Will be calculated financial and production results, received after implementation of new electricity generating systems on both enterprises. Will be considered the opportunity to sell the surplus of over-produced electricity to the citizens of nearby villages and cities, or to the Government.
