What are the lean production management methods of enterprises?

1. Moderate and appropriate manufacturing: that is, JIT manufacturing.

When necessary, we produce the necessary product in the necessary quantity".For the company, the production volume of various products must be able to flexibly adapt to the change in the demand of the sales market. Otherwise, overproduction will lead to a series of extravagant waste such as staff, machinery and equipment, and inventory spending.

The way to prevent this kind of extravagance and waste is to carry out appropriate manufacturing, and to produce and manufacture goods that are necessary for the sales market only when they are necessary for the sales market.

2. Ductile equipping the total number of safe operations.

In today's increasingly high cost of human capital, reducing human capital expenditure is one of the key aspects of cost control. The way to exceed this purpose is:"Fewer people".To put it bluntly, less manpower refers to the scalable adjustment of the total number of safe operations in each production line according to the change in total output, and the use of less human resources for more production and manufacturing as much as possible.

The key here is whether the number of safe workers in the production line has been reduced due to the total output. This? quot;Fewer people"The technology is reversed from the software of the manufacturing system over the years"Staffing"is a new and upgraded approach to staffing.

3. Quality commitment.

Over the years, I feel that there is a negative correlation between quality and cost, and to ensure quality, we have to spend human resources, manpower and material resources to ensure it in many aspects. However, in the JIT lean manufacturing method, the integrity of quality assurance and cost control is established according to the quality control around each process, and the specific method is automation technology.

The automation technology referred to here refers to the two systems that are integrated into the manufacturing organization

First, the system enables machinery and equipment or production lines to automatically identify defective goods, and if there is an abnormality or defective goods, the operation of machinery and equipment can be automatically terminated. Therefore, we develop, design, and install a variety of automatic termination equipment and production and processing inspection equipment on machinery and equipment;

Second, when the actual operators of the machinery and equipment in the production and manufacturing line find problems in the goods or machinery and equipment, they should terminate the management mode of production and manufacturing independently. With such a system, poor goods are detected as soon as they appear, and the recurrence or accumulation of poor goods is avoided, which in turn prevents a lot of luxury and waste that will result. In addition, if there is an abnormality, the production line or machinery will be terminated immediately.

It is easy to find the cause of the abnormality, and then it can be taken purposefully to avoid the recurrence of similar anomalies and the recurrence of similar suboptimal products.

Lean production is mainly to deal with multi-variety, low-volume production methods, with the aim of reducing factory costs, improving quality, and ensuring timely delivery.

The premise of the implementation of lean production is to do a good job in basic factory management. In a sense, this can also be said to be a lean production management method (combined with the situation of domestic small and medium-sized enterprises).

1. Establish a corresponding flat organizational structure and appropriate authorization.

2. Pre-planning of the product. Ensure the simplicity and accuracy of the product process. Timely verification.

3. Training (important).

and on-site management (including appropriate Kanban, etc.).

5. Total quality management.

6. Predictive maintenance of equipment.

7. Production line beat.

8. **Chain management.

9. Inventory management.

10. Fast logistics and reduce waste.

11. Error-proofing technology (FMEA).

12. Finance attaches importance to the early development cost and the analysis of the cost of individual product quality.

13. Rewards, punishments and incentives.

14. Smooth information transmission mechanism.

15. Continuous improvement.

16. Company management culture. or leadership style.

Sudden 1: Raise awareness and strengthen organizational leadership.

The key to implementing lean manufacturing is to bring the role of employees into play. Strengthen the education and training of lean management awareness for all employees, and the participants must be from the bosses and vice presidents of the management level to the general workers at the operational level. The training includes:

Competitive situation, waste concept, incentive production, 5S, team improvement, full set of equipment management, quality management, etc., in order to promote the concept and concept change of all employees of the enterprise, enhance the awareness and initiative to implement lean production methods. Establish a leadership and implementation organization specifically responsible for the implementation of lean production methods, which is responsible for the general manager and the participation of the heads of relevant business management departments, clarify responsibilities and tasks, formulate lean production work plans, and promote the implementation of lean production methods. Lean production methods in the enterprise.

Step 2: Establish the project leader and project execution team.

This step is to establish a lean manufacturing organization. This is also a necessary step for many companies to implement lean manufacturing. Some companies refer to the group as the "Lean Manufacturing Committee," while others refer to it as the Kaizen Organization.

In general, the general manager should be the head of the lean organization. Some companies also list the deputy general manager of the factory as the person in charge. The organization should include the production management department, the manufacturing department, the production technology department, the quality department and other related departments.

The supervisor should establish the improvement responsibility of the person in charge.

Step 3: Establish a demonstration production line and determine the management model.

Three to six months after the implementation of lean production methods, when the initial results of 5S are achieved, a production line should be selected as a demonstration to promote continuous improvement. To improve the content, make the most of lean tools, while paying attention to the selection of the assembly line and clearly improving the previous status, such as: finished goods and parts lists, flow charts of current objects and information, time surveys for each item, inventory surveys on the side of the production line, and frequency and quantity of deliveries.

Improvement must adhere to the principle of gradual progress, implement the person in charge, and pay attention to the use of brainstorming method to pool the wisdom of all personnel. Improvements must be posted in a timely manner to ensure that improvements are implemented and collaborated smoothly at the same time. At the same time, the person in charge of the improvement demonstration line must confirm the progress of the improvement on a daily basis.

Step 4: Field improvement from 5s.

5S Management (Organize, Correct, Clean, Clean, Finish). To implement lean manufacturing methods, we must first improve the on-site environment, clean up unnecessary items and reduce space occupancy; Place items on site in an orderly manner; After cleaning, keep the site clean and maintain the equipment maintenance in time: After inspection and rectification, employees will develop good habits to maintain a good site environment, thereby improving the company's production efficiency and product quality.

Finally, through the 5S activities, the orderly management of the site was realized, the waste was reduced, and the production management level of all employees was improved.

Improvement proposal system with the participation of all employees. Many people may feel more familiar, and many people will say that we have ah, we have a proposal system. However, the improvement proposal here is different from the proposal improvement, rationalization proposal, etc., the improvement proposal is to improve first and then propose, that is, to do it first, to improve first, and then to propose, which is completely different from our original proposal system.

The improvement proposal system is the basis for all employees to participate in continuous improvement. Start by reducing waste by all employees.

Improvement system for issues at the grassroots level. It is most appropriate for middle-level cadres who understand the situation of the production site to put forward improvement suggestions for on-site management and production processes, and formulate improvement plans.

Presentation system for all employees. Whether it is an improvement proposal or a major improvement issue, the results should be announced as a way to evaluate the results. The way of publication is not only a report, but also a live demonstration.

The results of the improvement will be displayed on the spot, and the participants in the presentation will share the improvement journey.

All staff training on relevant improvement tools. Through training, employees at all levels of the factory enterprise can master the relevant improvement tools, which is the basis for the continuous implementation of lean production management. If you don't master the improvement tools, you can't improve, and even if you do, you can't do it.

Therefore, training in improving tools is mandatory. It includes training at all levels from newcomers to veteran employees, to promoters, from grassroots to leadership.

Around 1980, FAW belonged to the First Machinery Department, and at that time, it carried out the selection of the honorary title of quality trustworthy team, which I think was the predecessor of lean production. I remember that at that time, what we pursued was never satisfied with qualification, but had to achieve the best! This is undoubtedly a huge test of your operating skills and sense of responsibility, looking back, we are worthy of the country, worthy of the meager wages to support the family, worthy of conscience!

We use VIOOVI's ECRS man-hour analysis software, which can solve the problem of over-processing in the machining process, reducing the unnecessary processes, because these redundant processes will waste man-hours and affect production, and the implementation of lean production must not be low in the first place.

5S and visual control, just-in-time production (JIT), kanban management, zero inventory management, total production maintenance, etc.

Lean production is a praise for Toyota's production method, and also refers to the production organization and management mode with the characteristics of Toyota's production method. Lean production has two major characteristics; On-time production, full participation in improvement. It is precisely because of these two characteristics that it is possible to "get more and more output with less and less input."

The punctuality system was first developed by Toyota, led by Naichi Ohno. The purpose of the just-in-time system is to eliminate all kinds of actions that have no added value, and at the same time to achieve a production system that can be more flexible to adapt to changes in the needs of customer orders.

Because the repentance group is a training system, a suggestion system, and BSC cannot be implemented in Chinese enterprises, therefore, China Lean only has "Lean Improvement Tools".
