Improvement of the Model for Calculating the Operating Profit of Industrial Enterprises Taking into Account the Problem of Optimal Distribution of Productive Resources

On the ground of the conducted research, based on the stated goals and objectives, the model of calculating the operating profit of industrial enterprises, which is based on economic and mathematical dependencies, and takes into account the problem of optimal distribution of production resources in the system of operational management has been improved. Great attention has been paid to the analysis of the cost factors in the system of analysis of the ratio of “costs – volume – profit”, the definition of the optimal distribution of productive resources from the set of possible (admissible) ones in the organization of labor and production, the difference between accounting and economic approaches to calculating profit, the difference in approaches to the classification of overhead costs in terms of activity-based costing.On the ground of the conducted research, based on the stated goals and objectives, the model of calculating the operating profit of industrial enterprises, which is based on economic and mathematical dependencies, and takes into account the problem of optimal distribution of production resources in the system of operational management has been improved.

Increasing the competitiveness of enterprises based on the use of marketing management tools

Purpose. The purpose of the article is to substantiate the need to use marketing management tools to increase the competitiveness of the enterprise and create a model of interaction of tools in the implementation of marketing strategies. Methodology / approach. The research was conducted on the base of sociological methods by means of statistical questioning of 200 respondent-entrepreneurs, owners, or runners of small business in the Western Region of Ukraine. Using the analysis of variance, the authors of the article studied variation of the results of the sociological investigation on marketing management tools, used for implementation of different strategies of business development. The factorial analysis was used to describe the factor structure of the marketing management tools. The calculations are made with application of the software Statistica 8. Results. Substantiation of the use of marketing tools to increase the competitive advantage of enterprises based on the results of the conducted sociological interviewing of 200 respondent-entrepreneurs, owners or managers of small and medium-sized businesses. Referring to the results of the factorial analysis of marketing management tools, used for implementation of different strategies of business development, the researchers specify three factors. Originality / scientific novelty. For the first time, the model of interaction of marketing management tools in the context of implementation of marketing strategies is formed, and it is investigated a structure of marketing tools at implementation of various strategies of business development to increase competitiveness of the enterprises. Practical value / implications. The main purpose of using marketing management tools is determined, which will allow enterprises to coordinate their marketing activities, optimally allocate resources at all its stages and, as a result, will directly influence the formation and increase the level of competitiveness. The research results can be applied at enterprises of the Western region of Ukraine to provide substantiation of management decisions regarding improving competitiveness on the basis of marketing management

Economic-mathematical model of enterprise profit maximization in the system of sustainable development values

Purpose. The purpose of the research is to improve the economic-mathematical model of enterprise profit maximization in the system of sustainable development values. Methodology / approach. The work uses the methods of system analysis, systematization, generalization and specification, the graphic method and the method of comparison (of processes, indicators, etc.), as well as economic-and-mathematical methods of system modeling and expert methods. Results. It was improved the structural scheme (triple-continuum model as a conceptual scheme of information technology) of managing financial and technological processes, innovation risks, which takes into account the impact of innovations on the activity (internal variables, business processes) of the enterprise, restrictions (on production, implementation, supply, finance) and conditions of their compliance with the optimal amount of production (realization), as well as a synergistic effect in the context of profit maximization, in the system “type of innovation – type of development”, in the system of values of sustainable development. This structural scheme is the basis of the proposed economic-mathematical model of enterprise profit maximization in the sustainable development values. A multiplicative criterion of management efficiency is proposed, which includes methods for determining the level of quality of enterprise development and managing enterprise development in the “type of innovation – type of development” system. It was found that the level of quality of enterprise development (in the production management system and taking into account the system of marketing goals) depends on: the level of rhythmicity and defect-free production; level of satisfaction of consumer needs with finished products. Originality / scientific novelty. The economic-mathematical model of enterprise profit maximization in the sustainable development values has been improved, which is based on theoretical and applied principles of management, marketing, takes into account the peculiarities of the system of diagnostic goals of economic diagnostics, tools for monitoring the parameters of the enterprise's activity, their relationship, and also contains separate provisions of the theory constraints, methods of optimization and economic-mathematical modeling, and, unlike the existing ones, in view of the research of operations, allows solving the general economic problem in practice - enterprise profit maximization in the sustainable development values. Practical value / implications. The results of the research can be used in the practical activities of enterprises of all forms of ownership

Qualimetric Analysis of Pipelines with Corrosion Surfaces in the Monitoring System of Oil and Gas Enterprises

The introduction of new technologies for diagnosing underground metal pipelines with dangerous surface defects is a practically important task. That is why studies aimed at improving the methods of assessing the quality of deformed metal pipelines and structural elements are necessary and relevant. The evaluation of the effectiveness of engineering and technological solutions for oil and gas enterprises needs improvement. In this context, an important task is to solve the problem of quality control (including durability) of gas and oil transportation systems and the improvement of appropriate metrological support. Based on surface physics and fracture mechanics, development of a methodological approach to assessing the quality and resource of underground metal pipelines (UMP) of oil and gas enterprises, taking into account the constructions strength, corrosion fatigue, parameters of corrosion protection and metrological support. Results of processing of normative documents and scientific works in the field of gas transportation enterprises, as well as methods of surface physics, mechanics of deformed solid body, fracture mechanics, qualimetry regarding the system “pipeline (UMP) – coating”. A new criterion for the strength of the surface of a metal underground pipe is proposed, which characterizes the peculiarities of bond fractures (adhesion) between the coating and the metal. Using the criterion of the strength of a metal tube with a defect in the electrolyte, the dependence of the critical internal pressure of the gas pipeline (UMP) on the geometric and energy (elastic and plastic) parameters of the metal, as well as the current of the anodic dissolution, which characterizes the features of the crack propagation at the bottom of the corrosion cavern. On the basis of surface physics and fracture mechanics obtained, a methodology for evaluating the quality of underground metal pipelines of oil and gas enterprises was developed to determine their resource, taking into account strength, corrosion fatigue, parameters of corrosion protection and metrological support
