The methodology for assessing the spatial homogeneity of ecosystems with the possibility of subsequent zoning of territories in terms of the degree of disturbance of the environment is considered in the study. The degree of pollution of the water body was reconstructed on the basis of hydrochemical monitoring data and information on the level of the technogenic load in one year. As a result, the greatest environmental stress zones were isolated and correct zoning using geostatistical analysis techniques was proved. Mathematical algorithm computing system was implemented in an object-oriented programming C #. A software application has been obtained that allows quickly assessing the scale and spatial localization of pollution during the initial analysis of the environmental situation.
The paper presents the results of the development of a single integrated solution for the automation of technological processes of service enterprises of the oil and gas sector, which allows to organize the work of production and management in a single information space. Algorithms have been developed to solve individual problems that are interconnected into certain algorithmic modules. The results of the integration analysis of modern automation systems of the ERP-class are presented, in particular, the level of adaptation to the stages of the product life cycle, compliance with standards and safety requirements, the complexity of the transition to the automation system. The results of the analysis of possible risks of the project during the implementation of this algorithm are presented. The practical significance of the development of a single production management algorithm is described. Finally, the treatise evaluates the main advantages and economic effect of the introduction of an automation system for an enterprise engaged in the production of oil and gas pipes at the process control level.
The paper presents the basic methods for developing an expert system to assess the efficiency of power supply networks. The existing expert systems and possibility of their use to assess the efficiency of power supply systems have been analyzed. Mathematical models for network expertise, in particular, methods of the theory of choice and decision making were described. Decision-making algorithm for power grid based on differential evolution method is considered. The algorithm to calculate the reduced costs in designing power supply networks, allowing to develop the optimal expert system for control and assessment of power supply network efficiency, has been obtained.
of recession, outflow of investment, decline in production activity and the lack of stability of foreign economic and political situation attraction of investment resources becomes a pressing matter also in the framework of the decision behind the policy of import substitution. Instability on the external market and a quite difficult economic situation inside the country leads to the significant reduction of investment. This necessitated searching for the new investment sources and the new objects for investment. One of the most attractive kinds of economic activity for investment are the building sector and agriculture complex.
This work presents a developments of a single integrated solution for the process automation of oilfield service companies that allows organizing production and management systems in a single information space. The analysis of the main factors and causes that affect the occurrence of production losses, and their consequences. In the scope of this work, algorithms for solving individual automation problems that are interconnected into certain algorithm modules have been developed. The results of the integration analysis of modern ERP automation systems are presented, in particular, their level of adaptation to the stages of the product life cycle, compliance with standards and safety requirements, and the complexity of the transition to an automated system. Possible risks of the implementation of the algorithms were also assessed, describing an applied importance of the development of a single production control algorithm. Further, an evaluation of main advantages and economic effect of the introduction of process control automation system at the company manufacturing oil country tubular goods is presented.
