description: Topic of the final qualification work: The project of organization of defect-free production on the example of the rolling and annealing shop of Severstal. This work is devoted to the study of the production process of the rolling and annealing shop, finding the most problematic place in the process, evaluating the defect monitoring system and developing an algorithm for finding the root causes of defects. Tasks that were solved in the course of the study:1. Study and description of the production process of the rolling and annealing shop of Severstal.2. Identification of defects that occur in the production process.3. Analysis of the efficiency of work with defects in production.4. Development of proposals for the organization of defect-free production using statistical quality tools.5. Financial and economic justification of the project and risk assessment.6. Implementation of proposals for the organization of defect-free production based on the collected and analyzed data.7. Conclusions on the effectiveness of the implementation of these proposals.The work was carried out in the rolling and annealing shop, where most of the actual material was collected: the number of defective products for equipment, the rate of entry of metal rolls into the line, the time of operations. The calculation of the level of losses was carried out, allowing to determine the current situation at the enterprise. Losses were estimated using computer simulation in the Arena program.As a result, an algorithm was selected to find the root cause of defects. An assessment was made of its effectiveness in finding the root cause of defects associated with mechanical damage to the edge.
