The implementation of zero inventory model should have a strong national culture and corporate culture as the fulcrum. With the deepening of the study of zero inventory management, you will find that it is not just an operation and management technology, but also a culture, a philosophy, its success is the source of Japan to comply with the spirit of contract and stress the cultural essence of mutual co-ordination . In this case,

 

 Japan's many corporate system is matched with this belief, such as "life-long employment system", "the power of the system sequence" and so on. When this recognition culture is embodied in the enterprise and the enterprise, it will show mutual recognition and trust, that is, in the long-term dynamic activities, believe in each other in the process of business interaction with each other partner-style cooperation, which is the Japanese enterprises The cultural roots of the oral agreement approach to dealing with the business. Therefore, we should deeply understand the zero inventory model runs through the Japanese companies and the widespread use of the real reason. In this case,

 

 Zero inventory management has clear prerequisites:

 

 First, to ensure production and sales needs under the premise set goals, it is necessary to avoid the shortage of stock due to the phenomenon of raw material production, but also to prevent the shortage of goods due to shortage of stock phenomenon. Most of the products are sold and off-season season, the general use of off-season backlog of inventory to meet the needs of the season.

 

 If the implementation of the zero inventory, the season requires a considerable size of the production line, the off-season will have to reduce production, which for the production is unreasonable. To solve the production of seasonal, production and consumption needs of the inventory point of view, the inventory of the real "zero" goal is difficult for any business to achieve.

 

Second, to the overall cost of the optimal supply chain as the goal, each supply chain partners should share the appropriate amount of inventory. Through this management to control the amount of inventory to the best amount, with a minimum of human, material and financial resources to manage inventory. In this case,

 

Third, from the perspective of supply chain inventory management, zero inventory is to maintain a reasonable inventory, reasonable inventory will vary by country, region, industry, industry and business differences. Zero inventory can be expressed as speeding up the supply of beats, shorten the beat interval, thereby reducing the amount of material stocking; can also be expressed as reducing storage links, in the pursuit of production and sales of smooth and adequate allocation of resources under the premise to ensure the most reasonable inventory and the shortest Minimization of inventory costs at the time of the acquisition, as well as acquisition costs, inventory holding costs and out-of-stock losses. In this case,

 

Fourth, we must carefully analyze the actual situation of their own enterprises. For the enterprise on the supply chain node, want to reduce the inventory of the feasibility of a way to achieve zero inventory, but this approach is to reduce the supply chain, a way of self-inventory. Through the cost analysis shows that the zero inventory is not necessarily the best way to profit, Toyota, Dell and other advanced management level of enterprises is difficult to achieve ordinary enterprises. In this case,

 

As a wise operator, should understand that any management tools and technologies are required to pay a certain cost and cost, in the choice of any kind of management tools and techniques, should try to do less than the output of inputs. Therefore, companies should be a pragmatic attitude, to achieve the cost of zero inventory and achieve zero inventory of the proceeds after the regular comparison of investment and construction costs, management costs and inventory savings of the relationship between the balance of enterprises to implement zero inventory gains and losses and then And then to determine the enterprise's supply chain logistics strategy and inventory control strategy.

 

The successful implementation of zero inventory management is inseparable from the enterprise's strict internal management and excellent and efficient external conditions to support, while the need to overcome the constraints of enterprises to achieve zero inventory factors, such as internal and external environment, material procurement market, product sales market, And supply time and other factors. Without these conditions, the results will only be their own inventory pressure and internal logistics issues on the overall operation of the other links.

 

 For the realization of zero inventory and the cost will be much higher than the zero inventory management of the benefits, the negative effects will worsen the enterprise operating system, weakening the overall competitiveness of enterprises, and ultimately damage their own interests.

 

 Dialectical analysis of zero inventory based on inventory classification. Inventory has many functions, and the inventory function is in the rationalization of the inventory structure under the conditions can be fully developed, it must be for the popular concept of zero inventory, the dialectical thinking. From the different functions of the inventory can be divided into: regular inventory, safety stock, seasonal inventory, promotional inventory, speculative inventory, spare parts inventory, working capital, inventory in transit, commissioned processing inventory, commissioned consignment inventory and sluggish inventory.

 

 Zero inventory is mainly for the backlog of inventory and regular inventory. There are different management modes and inventory control strategies for different production methods. Each inventory management method also has its own shortcomings or needs special attention. For example, the inventory management methods are different from each other. local.

 

 In the social environment due to too many uncertainties, such as supply and demand uncertainty, demand for personalized, unexpected events, ahead of time, the transport of goods, raw material quality and production anomalies. Therefore, the zero inventory management theory is not applicable to all products, the need to integrate the use of a variety of inventory management methods, learn from each other, only to achieve more meaningful. In this case,

 

According to the classification of inventory also shows that inventory can not be completely reduced to zero. In fact, the purchase order after the formation of procurement actions have occurred in transit materials, it began to produce inventory. Enterprises in order to eliminate the separation of production and marketing, supply shortages, transport delays, fluctuations in demand, hedging and other phenomena arising from inventory can not be implemented clear "zero" campaign, there should be adequate inventory to meet normal needs.

 

So, specific to the enterprise of a product, which inventory management should be emphasized, you can use a simple measure to measure: If the product is in short supply, there is the potential for appreciation, the appropriate inventory may bring more High revenue; the other hand, can be "zero inventory management." Of course, the "appropriate inventory" is not "a lot of inventory", in addition to consider the cash flow and inventory costs and other cost estimates, the need to prevent supply and demand errors caused by the hidden cost of judgments.

 

Zero inventory can not completely replac the minimum safe stock. Enterprises can not accurately predict future market demand changes, in order to effectively alleviate the contradiction between supply and demand to maintain uninterrupted production and business activities, it is necessary to hold a certain amount of inventory. As the company's inventory can not be zero, so companies can be based on cost-effectiveness and safety of the best stock as the enterprise inventory limit.

 

It is worth noting that the traditional inventory management hopes to solve the problem of ordering time and order quantity, both to protect the supply, but also to minimize the amount of reserves of thought. And the key point of modern inventory management is to increase the inventory location, the type of goods and collocation and other content, its fundamental goal is to achieve a reasonable supply through the appropriate inventory, so that the total cost of the lowest inventory; the key is the overall flow of inventory value, "Keep the total cost of the supply chain the lowest" decision-making.

 

Zero inventory management model is not suitable for the current situation in China. Toyota automobile assembly line to do the production of zero inventory, in addition to its own advanced and effective management tools and means, but also thanks to its hundreds of spare parts suppliers will be located in its factory around the factory, or raw materials Warehouse layout in the vicinity of their factories, to ensure timely delivery, accurate.

 

Zero inventory is based on "zero distance" on top of the supply, but also based on the reliability and trust of suppliers based on. It requires the management of enterprises to be very stable, does not allow a small deviation caused by discontinued; also need a relatively fixed supplier groups and agree with Toyota's corporate culture characteristics, can effectively implement the "zero inventory strategy."

 

The actual situation in China at this stage is that the majority of small-scale enterprises, the stability of suppliers and logistics and distribution is poor, the supply chain nodes of the lack of information sharing, coupled with market changes and weak enterprise itself, management level, If the rush to choose the Toyota-style small batch, multi-batch purchase mode, which may bring some transportation costs or production of uncoordinated factors, resulting in production due to lack of material and blocked, resulting in increased contradiction between supply and demand, shutdown huge losses will Can not make up, may lead to its cost savings greater than zero inventory.

 

China's manufacturing industry in order to use zero inventory management, just by learning and learning Toyota zero inventory management method is not enough, it is necessary to combine their own characteristics and the actual conditions of the industry chain to explore the implementation of the possibility of zero inventory management and reality . Therefore, enterprises in the implementation of zero inventory management, should actively think, prudent exploration, scientific grafting, to improve its operation for China's national conditions, can not blindly copy, to have a choice, some innovation.
