As an important part of thermal power generation equipment, the lean management of the production process of thermal power forging is of great significance to improve product quality, reduce production cost and enhance the competitiveness of enterprises. In recent years, with the adjustment of energy structure and the growth of power demand, the production of thermal power forgings is facing higher requirements and challenges. Therefore, this study aims to explore the lean management in the production process of thermal power forgings to improve production efficiency and quality.
Lean management originated from the Toyota production mode, is a customer demand-oriented management method by eliminating waste, reducing costs, improving efficiency and quality. In the production process of thermal power forging, lean management is mainly reflected in the following aspects:
Production planning Lean: Through accurate production planning and scheduling, ensure the smooth and efficient production process.
Production process lean: By optimizing the production process and improving the utilization rate of equipment, reduce production costs and improve product quality.
Lean supply chain management: Ensure the supply and quality of raw materials by establishing stable cooperative relationships with suppliers.
Lean human resource management: Improve the skills and motivation of employees through training and incentive mechanisms.
At present, many scholars at home and abroad have studied the lean management in the production process of thermal power forging. For example, Li (2019) found that lean management can effectively improve production efficiency and quality and reduce production costs through field investigation of a thermal power plant. Zhang (2020) found that lean management can significantly reduce waste in the production process through simulation research on thermal power forging production process.
In this study, questionnaire survey and interview were used to investigate the production process of thermal power forging in a thermal power plant. First of all, through the questionnaire survey to understand the production status and management of the factory; Then, interviews are conducted to gain insight into specific problems and management experiences in the production process. Finally, the results of questionnaire survey and interview are analyzed and summarized.
Through questionnaire survey and interview, it is found that the following problems exist in the production process of the factory:
Production planning is not precise enough, resulting in waiting and waste in the production process.
The production process is not optimized enough, resulting in low equipment utilization and unstable product quality.
Supply chain management is not tight enough, resulting in raw material supply instability and quality issues.
Human resource management is not precise enough, resulting in low skills and motivation of employees.
In response to the above problems, this study proposes the following lean management schemes:
Optimize production planning: Reduce waiting and waste in the production process through accurate production planning and scheduling. For example, tools such as Kanban management systems can be used for real-time monitoring and adjustment.
Optimize the production process: By optimizing the production process and improving the utilization rate of equipment, reduce production costs and improve product quality. For example, methods such as six Sigma can be used for process improvement and equipment maintenance.
Strengthen supply chain management: Ensure the supply and quality of raw materials by establishing stable cooperative relationships with suppliers. For example, tools such as vendor evaluation systems can be used for management and monitoring.
Strengthen human resource management: improve the skills and motivation of employees through training and incentive mechanisms. For example, tools such as performance appraisal systems can be used for motivation and training.
Through the field investigation and analysis of the production process of thermal power forgings in a thermal power plant, it is found that lean management can effectively improve production efficiency and quality, and reduce production cost. Future research can further integrate advanced means such as the Internet and intelligent technology to improve production efficiency and quality. For example, the Internet of Things technology can be used to achieve remote monitoring and maintenance of equipment; Big data analysis technology can be used to achieve intelligent optimization of the production process. At the same time, it is also necessary to constantly research and explore new management methods and tools to meet the changing market needs and industry development. In short, lean management is of great significance and application value in the production process of thermal power forgings, which is worth further research and popularization.
