ANALYSIS OF THE APPLICATION OF LEAN MANUFACTURING TOOLS ON THE EXAMPLE OF EUROPEAN COUNTRIES

Lean manufacturing is one of the key technologies in improving the quality and efficiency of production processes in the domestic and global economy. The purpose of the study is to analyze the application of lean manufacturing technologies on the example of European countries. Materials and methods. The study was conducted based on the analysis of tweets downloaded for the period 2021-2022 by the keyword «lean», taking into account geolocation. The tonality and subjectivity of tweets were evaluated using sentiment analysis methods, the Text Blob library was used. The calculations were performed in the Colab environment using the Python programming language. Research results and discussion. The total number of downloaded tweets is 19660. The number of tweets published in Europe on a monthly basis is random, there is no trend and seasonal component in the structure of the time series. The use of individual lean manufacturing tools is actively discussed on Twitter. It is determined that the application of lean manufacturing technologies in these countries is combined with the introduction of innovations and the creation of startups. The most actively used lean manufacturing tools in European countries are kaizen, kanban, and the 5S system. Practically, when implementing production processes in European countries, the technology of mapping the flow of value creation is not used. The description of these instruments has high positive tonality values, which indicates a sufficiently high efficiency of their use. Conclusion. In Russia, the use of lean manufacturing technologies is limited, in the domestic professional community they often have a negative attitude to such tools, noting the complexity of their application in solving import substitution problems in domestic industry. The results of the author's research can be used to develop mechanisms for introducing these technologies into the Russian economy and improving the quality of goods and services produced.
