The development of Industry 4.0 concepts, used in high-tech industries and blockchain production information systems, enables the creation of smart factories with online alarm management systems, to improve manufacturing efficiency and reduce human resource requirements. In this paper, the performances of the causal association assessment model and the technique for order preference by similarity to the ideal solution (TOPSIS) model in evaluating large data blockchain technologies and quality online real-time early warning systems for production and raw material supplier management are compared, to increase the intelligence of production and to manage product traceability.104 bytestext/htmlmedium-sized enterprisecollaborative technologyIndustry 4.0intelligent alarm management system (IAMS)cause-effect grey relational analysis (CEGRA)technique for order preference by similarity to the ideal solution (TOPSIS)article
