Research on the application of jit management mode in Toyota JIT management

Abstract: JIT(Just In Time) production mode originated from Toyota Motor Corporation of Japan, which is a low-cost, high-quality flexible production mode born in Japan. The basic idea of JIT production mode is to produce the required products within the required time and quantity. In the second half of last century, the manufacturing industry entered a brand-new era. The large-scale production mode of a single variety can no longer meet the requirements of the new market, and the market demand has diversified. At present, there is an urgent need for a new production mode, that is, a small batch, multi-variety, low-cost and high-quality production mode.

With the integration of China's economy into the world economy, more and more products made in China have entered the international market. The global market economy has brought opportunities to enterprises and fierce market competition. In order to enhance the competitiveness of enterprises and blindly reduce the cost of materials, it is difficult to maximize the profits of enterprises. At this time, the emergence of a new mode of production-JIT mode of production has created new competitive advantages for enterprises.

Since 1980s, with the diversification of global market demand, the requirements for product quality, price and performance have become higher, the product development cycle has been shortened, and the market should be flexible. In this context, the emergence of JIT production mode has greatly met the new needs of market changes. All walks of life around the world have explored and studied the JIT production and management model, conducted field research, integrated theory with practice, and obtained a lean production model after comprehensive refining and summary.

Lean production, as its name implies, expresses the production and management concept of eliminating waste and saving resources. The theory is applied to the whole supply chain process, that is, the whole process from accepting customer orders, arranging production plans, making raw material procurement plans, transporting goods at home and abroad to delivery. At the same time, lean production has also been applied to the overall management of enterprises. In recent years, JIT management has been widely used in China's automobile industry, electronics industry, machinery industry, electrical industry and other manufacturing enterprises, which has improved production efficiency and achieved remarkable results. Just-in-time production and management methods have improved the economic benefits of enterprises. Enterprises have gained rich experience in production and management while reducing operating costs, and JIT production mode has been widely promoted and applied.

The goal of 1.JIT production mode

The ultimate goal of JIT production mode is to maximize profits and achieve zero waste. Any production activity that will not bring benefits to the enterprise is a waste, which can be summarized as:

1. 1 zero inventory

Zero inventory management is the key of enterprise supply chain management. As far as manufacturing industry is concerned, it refers to the time to eliminate raw materials, semi-finished products and finished products in the production process. Reduce invalid action time, such as reducing handling actions and times, and reducing waiting time caused by material shortage; Make production according to the order, and effectively control the product inventory of the enterprise.

1.2 Zero defect

Enterprises should take quality as the center and implement full participation management. The overall quality of an enterprise includes product quality, service quality, cost quality and quality management throughout the whole production process. In order to improve customer satisfaction, eliminate defects and reduce waste, enterprises need to establish a perfect quality assurance system. If there is a problem in the production process, it is necessary to stop production immediately, so that the problem can be fully exposed, analyzed and improved. Over time, problems in production will be reduced and product quality will be improved.

2.JIT procurement

2. Advantages of1JIT procurement

2. 1. 1 Reduce raw material inventory and improve inventory turnover.

The implementation of JIT procurement can gradually reduce the raw material inventory of enterprises, reduce the occupation of working capital, accelerate the turnover of working capital, and thus reduce the material inventory cost. At the same time, JIT procurement requires enterprises to conduct comprehensive and scientific management of suppliers. The procurement under JIT mode has stricter requirements for suppliers, faster response and stricter quality requirements. The implementation of JIT procurement has greatly improved the management level of enterprises themselves and suppliers.

2. 1.2 Reduce the quality cost of enterprises and improve the quality of purchased materials.

JIT procurement can improve the quality of purchased materials exponentially. According to the investigation, JIT procurement can reduce the quality cost of enterprises and is a means to measure and optimize the quality management of enterprises. JIT procurement requires that the quality responsibility belongs to the supplier. At the same time, due to the improvement of purchasing materials and the reduction of material quality cost, it provides a good business environment for enterprises to save resources.

2. 1.3 Expose the problems existing in the production process and improve the production efficiency of enterprises.

JIT procurement believes that excessive inventory not only increases the inventory cost of enterprises, but also holds them back.

Cash flow also covers up all kinds of contradictions in the process of enterprise production management. If the problems in production are not solved, it will certainly hinder the development of enterprises and reduce their production efficiency. JIT procurement can reduce the inventory of raw materials, constantly expose the problems in the production process, and solve the problems from the root causes, thus improving the production efficiency of enterprises.

2. 1.4 Require suppliers to deliver goods on time to improve the continuity and stability of production.

Requiring suppliers to deliver goods on time is another important feature of JIT procurement. First of all, in order to

In order to ensure on-time delivery, suppliers need to improve the production stability of their own enterprises and continuously improve their own output.

Product quality, so as to avoid delivery delay caused by unstable production and product quality problems. Secondly,

Enterprises need to constantly improve the production management process of suppliers, and also require suppliers to adopt JIT.

Management mode, synchronization with customers, to achieve a win-win situation.

2.2JIT procurement issues

2.2. 1 purchase price problem

JIT procurement mostly adopts the mode of single supplier supply, which leads to the cost of raw material procurement according to

Dependence on suppliers is not conducive to controlling the purchase price of enterprises, which brings troubles to the management of procurement cost of enterprises.

Corresponding risks.

2.2.2 Quality problems

JIT procurement has a single source and does not need incoming inspection. Suppliers send raw materials directly to.

Once the production line and suppliers' products have quality problems, the products of enterprises will also be affected.

Information disclosure

JIT procurement involves information sharing with suppliers. In the process of cooperation between enterprises and suppliers, suppliers will know some important internal information, such as the company's capacity plan, production data, product technology and so on. And there is a certain risk of internal information disclosure in the process of cooperation with suppliers.

2.2.4 Inventory problems

Both enterprises and suppliers will stop production due to abnormal conditions. In the process of JIT procurement, if the supplier stops production, the production of the enterprise will be out of stock. If the production line is stopped, the inventory of suppliers and semi-finished products will increase.

Supplier cooperation problem

JIT procurement management transfers the inventory cost pressure to suppliers, and the inventory cost pressure of enterprises is relatively small. Under the pressure of cost, suppliers will gradually lose interest in enterprise cooperation, leaving enterprises in a passive position, which is not conducive to long-term cooperation between enterprises and suppliers.

3. Comparison between 3.JIT procurement and large-scale procurement

3. 1 supplier selection

In terms of supplier selection, JIT procurement selects fewer suppliers, even a single supplier, and the relationship between enterprises and suppliers is stable, and the quality of purchased materials is relatively stable. Traditional large-scale procurement chooses more suppliers and often changes suppliers. The cooperative relationship between enterprises and suppliers is not firm, and there are many quality problems of purchased materials.

3.2 Supplier's Delivery Method

With regard to the supplier's delivery mode, JIT procurement mode is that the supplier arranges the delivery himself, and the enterprise procurement personnel do not need to spend a lot of time communicating with the supplier to arrange the delivery, which greatly shortens the workload of the buyer, improves the work efficiency and ensures the punctuality of the delivery. In the traditional way of bulk purchasing, the enterprise purchasing personnel inform the suppliers to deliver the goods, and the buyer needs to spend more time communicating with each supplier to ensure that the supplier's delivery meets the production needs of the enterprise.

3.3 Purchasing Batch and Logistics Transportation Mode

With regard to purchase batches and logistics transportation modes, JIT purchases more batches, fewer quantities, and logistics transportation is more frequent. The traditional bulk purchase has fewer batches and more quantities, and the logistics and transportation times are relatively few.

3.4 Inventory management mode

In inventory management, JIT procurement requires enterprises to deliver what they need when they need it, and suppliers deliver it directly to the demand point according to the requirements. The inventory pressure of raw materials and purchased parts is on the supplier side. Traditional bulk purchasing is an inventory-oriented management model. A large number of suppliers deliver goods, which ensures the production and operation of enterprises with certain inventory, and the inventory pressure is on the enterprise side.

3.5 Packaging requirements

For the packaging requirements of purchased parts, JIT procurement adopts standard, specific and reusable container packaging to save product cost. Traditional bulk purchasing uses non-reusable containers such as cartons, and there is no specific requirement for such packaging.

3.6 incoming inspection method

Regarding incoming inspection, JIT procurement requires strict quality of suppliers, and the quality of purchased raw materials and purchased parts is guaranteed. At the same time, JIT procurement requires suppliers to supply goods at demand points, and suppliers do not need incoming inspection for delivery, thus shortening the procurement cycle and improving production efficiency. The traditional bulk purchasing method requires suppliers to arrange incoming inspection every time they deliver goods.

2 1 century, due to the rapid development of the world economy, the globalization of market economy urgently requires us to adopt advanced and effective management methods to ensure the sustained and stable development of enterprises. The emergence of JIT production management method is the product of global economic development. JIT's advanced scientific management mode is widely adopted by domestic enterprises to maximize their profits. It is of great significance for enterprises to integrate into the international market and move towards internationalization. JIT production management is a comprehensive and complex management system, which involves human resources, technology, R&D, production, sales, logistics, supply, quality and other departments. JIT thought is integrated into the overall strategic operation of the enterprise, which is constantly improved and perfected in practice, and gradually forms a management model suitable for the enterprise's own characteristics, reducing enterprise waste, reducing enterprise costs and realizing real lean production. JIT management model has reference significance for the reform of enterprises in China. It not only improves the management level of enterprises, enhances their market competitiveness, but also maximizes their benefits. With the support of e-commerce and information network technology, JIT is in an invincible position in the global market.
