  • EVALUATION OF INNOVATIVE MANAGEMENT METHODS IN COMBINATION WITH DECARBONIZATION STRATEGIES: INTERACTION EFFECTS AND RECOMMENDATIONS FOR DOMESTIC ENTERPRISES
    A. ARUTIUNIAN, O. ZHYTKEVYCH
    Science and Innovation, 2025
    Introduction. The integration of innovative management methods with corporate sustainability strategies hasbecome increasingly relevant across business sectors.Problem Statement. The challenge is to evaluate management methods when combined with decarbonization approaches to ensure both efficiency and environmental responsibility.Purpose. This study has investigated the impact of combined production management methods on key performance indicators of enterprises, including their advantages and disadvantages, application frameworks, managerial implementation, cultural aspects, and capacity planning under emission reduction requirements.Materials and Methods. A mixed-methods approach has been employed, combining qualitative and quantitative techniques to analyze innovative practices. Information-search, analytical, and comparative methods,along with cost-benefit and decision tree analysis, have been applied to develop practical recommendations.Results. A comprehensive comparative analysis of innovative production management methods — specificallyLean Manufacturing, Total Quality Management (TQM), Six Sigma, the Theory of Constraints (TOC), and Justin-Time (JIT) — has been presented. The study has examined similarities and differences across 20 criteria in both international and domestic enterprises, enabling decision-makers to gain deeper insight into their foundations. It has been demonstrated that integrating decarbonization with efficiency-focused methodologies optimizes resourceutilization. Practical recommendations for improving production processes have been developed, taking into account industry-specific characteristics and current operational challenges. Cost-benefit and decision tree analyses have confirmed the robustness of the proposed recommendations.Conclusions. The proposed approach has contributed to aligning sustainability objectives with profitability inmanufacturing enterprises. The findings have provided a foundation for further research in innovation management and for the development of practical solutions aimed at cost optimization, quality improvement, and enhanced customer satisfaction in the manufacturing sector.

  • DEVELOPMENT OF PRINCIPLES FOR CONSTRUCTION OF A RATIONAL METHOD FOR FORMALIZATION THE ASSESSMENT PROCESS OF THE NEGATIVE IMPACT OF THE ENVIRONMENTAL PROBLEM ON THE COMPETITIVE MARKET

    The object of research is environmental issue, caused by global warming which has negative impact on market. Since, any negative impact is associated with externalities, a market cannot be considered as an efficient market. According to the literature research, market with externalities cannot recover by itself.Thus, one of the most problematic places is the proper identification of the problem related to environmental factors. The identified problem and its impact on a market should be modeled to determine possible negative effects on market participants. Based on the study’s results it is possible to approach the development of alternative solutions to the problem in order to increase economic efficiency. Because environmental factors are dynamic and have significant impact on a market, it is not possible to ignore such a relationship, which can lead to a source of a wide range of dangers.The problem can be attributed to the not studied enough, which, in turn, provides a large field of activity for its further study.One of the productive ways to solve this problem is to perform an economic analysis of the environmental problem as an external problem and develop principles for building a rational method of formalizing the assessing process for the negative impact of environmental problems on the competitive market. This will make it possible to automate the process, which will serve as a basic aspect of developing a plan of further actions.To achieve this aim, the author analyzed the environmental factors caused by climate change and have an impact on the ecosystem and markets. The foundations and needs for a climate policy were also analyzed. The climate policy is designed to improve the situation. The basic principles of constructing a rational method of formalizing the process of assessing the negative impact of environmental problems on the competitive market have been proposed by the author.
