1. \”Mass Door- Construction and implementation of the Milestone-Control Point\” model

\”Quality Door-Milestone-Control Point\” full-process quality control method is a scientific and efficient management model summarized by CRRC Changke in the production and manufacturing process of high-speed EMUs. This model has set up different levels of supervision and control points throughout the production process and organized multi-function teams to conduct multi-level and multi-level reviews, achieving comprehensive monitoring and traceability of the production process.

1. Quality Door: Quality Door is the core of this mode and its inspiration It comes from the \”AND gate\” in electronic circuits, that is, the project can enter the next stage only when all conditions are met. In actual operation, quality gateways integrate quality planning, quality standards, quality elements, control methods and process management to ensure that each link meets the predetermined quality requirements.

2.Milestone: Milestones are key nodes in project progress and are used to control the overall progress and quality of the project. CRRC Changke sets multiple milestones to break down the complex production process into several stages to ensure the quality and progress of each stage. All are in controllable state.

3.Control point: Control points are the specific execution points of quality monitoring, distributed in all aspects of production. By setting control points before starting construction, during production process and after important processes, CRRC Changke can monitor the production process in real time

2. Implementation effects and innovation highlights

1. Product quality has been significantly improved/p>

Through the \”Quality Door-Milestone-Control Point\” mode, CRRC Changke has achieved refined management and quality control of the production process. Data shows that the implementation of this mode effectively improves the stability of the physical quality of the product. , fills many domestic technologiesThe technique is blank. For example, the CR450BF EMU produced by CRRC Changke performed well in actual line tests, and its comfort, energy consumption and noise control indicators are all better than international standards.

2. Promote technological innovation and management upgrade

This quality control model not only improves product quality, but also promotes technological innovation and management of enterprises. upgrade. CRRC Changke has overcome many key technical problems through integrated product development concepts and concentrated its advantageous resources, such as drag reduction and consumption reduction, vibration reduction and noise reduction, and integration of all-factor lightweight systems. In addition, CRRC Changke has also taken the lead in implementing a number of international standards such as ISO9001 quality management system and IRIS international railway industry quality management system in the domestic industry.

3. Synergistic improvement of supply chain quality

CCCC Changke will \”quality\”The door-milestone-control point\” model has been promoted to the supply chain system, driving the quality improvement of upstream and downstream enterprises. Through in-depth cooperation with suppliers, CRRC Changke has achieved full-chain quality monitoring from raw material procurement to finished product delivery, which is powerful Promote the improvement of the overall quality level of the industry.

3. Industry impact and future prospects

The success of the whole process quality control method of \”Quality Door-Milestone-Control Point\” Implementation has won wide market recognition and industry praise for CRRC Changke. In 2013, CRRC Changke won the first China Quality Award nomination award, becoming the only company in the rail transit equipment manufacturing industry to win this honor. In addition, this model also It was promoted to other companies under CRRC and became a benchmark for quality control in the industry.

In the future development, CRRC Changke will continue to deepen the application of the \”quality door-milestone-control point\” model, and combine digital technology to further improve the quality management level. By With technical means such as big data and the Internet of Things, CRRC Changke will realize real-time collection and analysis of quality data, and promote the development of quality management towards intelligence and refinement.

In short, the implementation of the full-process quality control method of \”quality door-milestone-control point\” not only brings significant economic and social benefits to CRRC Changke, but also to my country\’s rail transit equipment manufacturing industry. High-quality development provides valuable experience.
