On the Inventory Management of Enterprises

Paper Keywords: inventory management, value storage, maintenance

This paper expounds enterprise inventory management from aspects of strengthening receiving management, strengthening storage management, paying attention to commodity value change, and commodity maintenance, so as to help enterprises improve efficiency.

The so-called inventory, objectively speaking, is the reserve materials used by enterprises for future sales or use, including raw materials, semi-finished products, finished products and other different forms. According to the definition of management, inventory is the stagnation and storage of anything with economic value, and its main function is to effectively alleviate the contradiction between supply and demand and make production and operation as unified as possible. Practice has proved that reasonable inventory will promote the efficient operation of enterprise production and operation. On the other hand, unreasonable inventory, such as too scattered inventory and overstocked materials, will hinder the development of production and operation of enterprises and affect their economic benefits.

First, strengthen the management of receiving goods

Receiving goods is to receive or pick up goods according to the storage plan and the delivery or arrival notice of the delivery unit and carrier, and make all preparations for warehousing.

1. Contact the delivery unit and the carrier. This work is to establish contact with the delivery or carrier according to the agreement or contract of the business department, so as to grasp the relevant information of receiving goods, thus making the receiving plan and arranging the manpower or material resources for receiving goods.

2. Make a receiving plan. On the basis of fully grasping the basic situation of arrival time, quantity, weight and volume, and according to the receiving power and the business requirements of the whole enterprise, negotiate with relevant business departments. The receiving plan has two main contents: on the one hand, it is to negotiate with the shipping department according to the internal situation, and on the other hand, it is to arrange the receiving time, receiving personnel, receiving place and receiving equipment of the unit according to the plan of the shipping department.

3. Go through the receiving formalities. According to the receiving plan, all functional departments will handle various receiving procedures within the determined planned time, such as picking up or receiving goods, financial procedures, etc.

4. Arrival processing. Unloading, handling, checking, counting, and signing for the arrival of goods shall be carried out when all formalities are completed or in progress, and shall be temporarily stored in appropriate places.

5. Acceptance work. According to the requirements of the receiving plan, according to the relevant contracts or other documents, verify, check and inspect the arrival of goods, so as to finally confirm the completeness and accuracy of receiving goods. There are three main contents in the acceptance work. One is verification, that is, verifying the relevant documents of the goods, such as checking the name, place of origin, certification materials, factory date, packing list and receiving and dispatching procedures; The second item is quantity acceptance, that is, according to the quantity index, check the total arrival quantity, unit packaging quantity and other contents; The third item is the quality acceptance and appearance quality inspection of goods.

Second, strengthen trusteeship management.

Custody is a work link to protect, maintain and manage the warehousing materials according to the characteristics of the goods themselves and the requirements of the warehousing plan.

1. Contact with the receiving unit and the using unit. Warehousing is restricted by receiving and using goods, so we must fully grasp and understand the information of receiving and using goods in order to arrange warehousing work in a planned way.

2. Make a storage plan. According to the characteristics of storage objects, the storage plan is made on the basis of mastering the storage time and quantity requirements. The storage plan mainly includes several aspects: first, the storage quantity plan. The storage quantity is decided not by the storage department, but by the business department, but the storage conditions, places and manpower are the main factors that determine the storage quantity and are also the basis of the plan. At the same time, the implementation point of inventory control is in the warehousing department, which is also one of the departments that make inventory plans. The second is classified management plan, which rationally plans storage places and storage methods according to the varieties, specifications and quality characteristics of inventory items. The third is the maintenance plan, which arranges the maintenance time, method, manpower and material resources according to the characteristics and storage time of the inventory.

3. Go through the warehousing and outbound procedures. The vouchers generated during warehousing and warehousing are the important basic work of storage and the basic information of system management, finance and statistical analysis. The warehousing procedure mainly includes the receipt of various vouchers and the establishment of custody accounts; The stock-out procedure mainly includes checking and processing various stock-out vouchers, and notifying the stock of stock-out.

Third, pay attention to the change of value.

During storage, the value of materials may change as follows:

1. Dull loss. Storage time is too long, although the use value of raw materials has not changed, but the demand of enterprises has changed, thus reducing the utility of materials, unable to continue to use according to the original value, forming dull materials piled up on the storage site for a long time. These materials will eventually be reduced in price or scrapped, and the resulting loss is dull loss.

2. Loss of time value. Material storage is actually a form of money storage. The time value of capital determines that every time it is stored, it will depreciate according to certain laws. All stored things will inevitably occupy funds, and the use of funds will pay a certain interest. The longer the deposit time, the more interest will be paid, or the longer the deposit time, the greater the opportunity investment loss of funds. This is a loss that cannot be ignored during storage.

Fourth, pay attention to the maintenance and maintenance of materials.

The significance of material maintenance is all the work that makes the use value of stored goods not decrease through certain environmental conditions and specific technical measures. The main contents of maintenance work are as follows:

1. Create environmental conditions suitable for material storage. This is the fundamental measure to maintain the goods, which can effectively prevent and control the goods from changing under suitable environmental conditions.

2. Control the main environmental conditions, such as temperature conditions, humidity conditions and sealing isolation conditions, to protect materials.

3. Single technical disposal of some stored materials, that is, technical measures are taken for some materials. The main technical measures are: (1) single product packaging. (2) Spraying protection of material surface. (3) chemical reagents are applied to the surface of materials. (4) Gas phase rust prevention. (5) Spray water for humidification and cooling.

Fifth, reduce unreasonable storage

Unreasonable storage is mainly manifested in two aspects. On the one hand, the storage technology is unreasonable, resulting in the loss of goods; On the other hand, the management and organization of warehousing are unreasonable, which can not give full play to the role of warehousing as a profit source. The main unreasonable storage forms are: (1) long storage time. (2) The storage capacity is too large. (3) The storage capacity is too low. Too low storage capacity will seriously reduce the ability of storage to guarantee supply, production and consumption. (4) The storage structure is unbalanced. The storage structure is the proportional relationship of storage objects, and the proportional relationship of storage objects will be unbalanced whether it is macro or micro. This imbalance is manifested in the following aspects: {1} The varieties, specifications and colors of the items stored are unbalanced. There is a phenomenon that the total amount is normal, but the specifications and colors of different varieties are different. {2} The storage period and storage quantity of different varieties, specifications and colors of stored goods are unbalanced. There is an imbalance between space and time, or between space and time. {3} storage dislocation. In a wide geographical location or local storage location, there should be no, less is more, and more is less.

In short, it is necessary to strengthen the sense of responsibility for inventory management, sign a letter of responsibility, and require the storekeeper to strictly control and resolutely put an end to the storage of materials with quality problems. It is strictly forbidden to lose, damage or rust the inventory materials due to neglect of management. Only when everything is done according to the system and the enthusiasm of inventory managers is mobilized can inventory management truly achieve the purpose of plugging loopholes and improving efficiency.

On the effective ways to reduce the internal inventory of enterprises Author: Cheng Longjie

Paper Keywords: material reserve quota management to improve efficiency

Abstract: Material management is an important part of enterprise management. How to reasonably control purchasing, inventory and effective utilization plays an important role in energy saving and efficiency improvement.

In order to ensure the production of enterprises can be carried out rhythmically, a certain material reserve is necessary, but not too much. Excessive reserves will make enterprises occupy a lot of working capital and warehouse area, and increase storage costs. Moreover, long-term storage of materials will reduce the use value of materials and cause waste, which will inevitably increase production costs and reduce the economic benefits of production. Therefore, strengthening inventory management is an important content of material management and even the whole production management. Effective ways to reduce enterprise material inventory mainly include the following aspects:

1 Make a reasonable material reserve quota.

Material reserve quota is an important basic material for enterprise material management, and its functions are as follows: ① It is an important basis for enterprises to make material purchase plans and determine purchase quantity, order batch and purchase time. ② It is an important tool for enterprises to master and adjust inventory changes and keep reserves at a reasonable level. (3) Determining the storage conditions of materials is the main basis for warehouse planning. (4) An important basis for the financial department to verify the working capital. Therefore, the correct formulation of material reserve quota is an important part of improving the management level of enterprises.

According to its specific function and different application conditions, material reserve quota generally has the following classification methods. ① According to different quota calculation units, it can be divided into relative reserve quota and absolute reserve quota; ② According to the different comprehensive degree of quota, it can be divided into single reserve quota and category reserve quota; ③ According to the different functions of the quota, it can be divided into regular reserve quota, insurance reserve quota and seasonal reserve quota.

2. Make a reasonable material purchasing plan.

Material procurement plan is a plan made by an enterprise to ensure the completion of production tasks and determine the demand for various materials during the planning period. It is the main basis for the enterprise's material supply department to organize procurement and purchase, and it is an important means to promote the development of enterprise production and do a good job in material management. The main basis for making a reasonable purchase plan is: ① monthly production plan of the production workshop; (2) the maintenance plan of the machine shop. (3) Material inventory of the supply department. When making a procurement plan, we should flexibly grasp the quantity of materials purchased and stored according to the law of market supply and demand and business needs. For long-term materials in the market, we should implement zero inventory management, make full use of social inventory, reduce manpower, material resources and storage space, and reduce the capital occupation of inventory materials. Reasonable purchasing plan can not only meet the material demand of enterprise production, but also will not cause new inventory backlog.

3. Strengthen material procurement management

Material procurement plan is implemented through market procurement. Under the condition that the total amount of purchased materials remains unchanged, the price of material procurement directly affects the occupation of inventory funds and the economic benefits of enterprises, so enterprises must strengthen the management of material procurement. The material supply department must organize the purchase according to the order, and shall not purchase by itself without the consent of the material supply department, so as to avoid the new inventory backlog caused by multi-head procurement. When purchasing materials, we must purchase in strict accordance with the purchasing principles and plans, ensure that the materials are well booked and not leaked, and do a good job in timely and accurate implementation of material supply. When signing a material procurement contract, the contract law and the company's contract management system should be strictly implemented. The contract shall specify the quantity, specification, model, price, quality standard, delivery date, delivery place, settlement method, freight and miscellaneous expenses undertaker, packaging, transportation, acceptance method, economic responsibility of the agent and other matters that need to be clarified. Generally speaking, it should be carried out according to the principle of first acceptance and then payment. Under special circumstances, the goods must be approved by the general manager, and the quality and quantity are wrong. For example, in recent years, in order to better manage the material supply, Fukang Smelter has successively issued management regulations such as Measures for the Management of Material Purchase Price of Fukang Smelter, Measures for the Management of Material Purchase of Fukang Smelter and Measures for the Management of Foreign Contract Agreements, which effectively standardized the material supply and management.

4. Strengthen the management of material consumption quota

Material consumption quota refers to the standard of the quantity of materials needed to manufacture a unit product or complete a unit workload under certain production technology organization conditions. Material consumption quota is an important technical and economic index in enterprise economic management, an important basis for correctly determining material demand and preparing material supply plan, and its function is an important basis for preparing material supply plan and calculating material demand; It is an important basis for enterprises to carry out material supply planning, material management, quota feeding, material consumption index assessment, strengthen economic accounting and determine the planned cost of products. It is a powerful tool to urge enterprises to increase production and save money; It is an important means to improve the production technology and management level of enterprises. Material consumption quota is generally revised once a year. The supply department provides the actual consumption data, and the production technology department modifies the process consumption quota. Due to poor management, the quota shall not be increased. Rational use and saving of raw materials in a planned way is an effective means to reduce the inventory of enterprises and speed up the turnover of working capital.

5. Do a good job in the management of inventory materials.

Enterprises should strengthen the management of inventory materials and improve the rules and regulations of warehousing management. The focus of warehouse management is to do a good job in the management of materials acceptance, storage and maintenance, and delivery. Warehousing acceptance requires accurate quantity, specification, quality and variety of materials, so that the accounts, cards, materials and funds are consistent; Storage and maintenance require all kinds of materials to be covered and padded, and piled up reasonably, firmly, quantitatively, neatly and conveniently; Strictly implement the requirements of issuing materials and leaving the warehouse, and the materials must be issued with a picking certificate, with complete and accurate procedures and the principle of first in first out. We should actively adjust the overstocked materials to avoid overstocking, damage and loss caused by poor management. Earnestly do the annual inventory of warehouse materials.

6. Do a good job in the management of waste materials.

Waste material management is an important part of enterprise material management. Strengthening the management of waste materials in enterprises can reduce the capital expenditure of material procurement, reduce inventory and increase economic benefits to a certain extent. The waste materials of an enterprise must be managed by the material supply department in a unified way, with the cooperation of other relevant departments (such as production technology department, machine maintenance workshop, and finance department of security department, etc.). ) should cooperate with each other. Waste materials should be sorted by relevant departments, and their use value should be identified together. Reduce inventory through maintenance and reuse, reorganization and replacement, degraded use and adjustment. Other waste products can only be sold after the price is confirmed and signed by the competent leader, and the unit cost can be reduced by selling the recovered funds.

In order to encourage the recycling of waste materials, waste materials generating units should reduce their costs according to a certain proportion of the actual sales of waste materials, and reward waste materials generating units according to a certain proportion. For example, in order to do a good job in waste management, Fukang Smelter has successively issued waste management regulations and supplementary regulations. In the aspect of repair and reuse, in recent years, the waste lead anode plate has been repaired and welded, and the damaged inner core of stainless steel valve has been reassembled and used. The development of this work not only saves a lot of purchasing funds, but also reduces the production cost of the workshop. In 2004, 700 lead anode plates and 174 valves were repaired and reused; In 2005, 650 lead anode plates and 164 valves were repaired and reused; In 2006, 400 lead anode plates and 43 valves were repaired and reused, with a cumulative value of 6,543,800 yuan.

7. Strengthen the training of material management personnel.

Material management is a modern emerging discipline that has gradually developed. In social production, the development and utilization of material resources need science and technology; Scientific management should promote the development and application of science and technology. In this sense, management is also a kind of resource, which is realized by material managers. Therefore, we must constantly strengthen the construction of material management team, strengthen the business and ideological and moral study of material management personnel, enhance service awareness and understand market dynamics. Through training, we can improve the professional level of material management personnel, realize the standardization, proceduralization, refinement and process of material management, and greatly improve the efficiency of material management. The "inventory" of an enterprise is a variety of materials stored to support production and maintenance. Inventory management should not only ensure accurate information to meet the needs of production and maintenance, but also have an important task of controlling inventory, accelerating inventory turnover and reducing the occupation of inventory funds, thus reducing inventory costs and improving the economic benefits of enterprises.

Application of Zero Inventory Management in Modern Enterprise Management Author: Huang Weicheng

Paper Keywords Zero Inventory Management; Modern enterprise; supply chain

Zero inventory management is an advanced management technology that was first widely used in Toyota Motor Corporation of Japan in 1970s. In recent years, zero inventory, as a general management model, has been widely used in logistics, e-commerce, medicine and health. However, there are still some vague understandings and biased practices on how to carry out zero inventory management in modern enterprises. Therefore, this paper discusses how modern enterprises carry out zero inventory management.

First, the connotation of zero inventory management

The ideas of zero inventory management mainly include: (1) zero inventory is an ideal state pursued by enterprise management. Zero inventory management sets a highest standard and limit for enterprises. The actual output can be infinitely close to zero inventory, but it may never be reached. By improving inventory management, enterprises can minimize inventory or even reach zero inventory, which can greatly improve the flexibility of production supply chain and make the production of enterprises truly meet the market demand. (2) Inventory does not increase the product value, which is a kind of "waste". The "waste" in enterprise management refers to the part that exceeds the "absolute minimum" of materials, machines and human resources necessary to increase the value of products. According to this concept, inventory does not increase the value, but increases the cost, which is a waste. Therefore, it is necessary to continuously reduce inventory and eliminate waste as much as possible to maximize the efficiency and performance of the production system. (3) The implementation of zero inventory management is a dynamic and continuous improvement process. Zero inventory management welcomes the emergence of problems, and its way is to improve the management level and efficiency by continuously reducing inventory, exposing problems and continuously improving, thus increasing the economic benefits of enterprises. However, enterprises can not simply reduce inventory, but always cooperate with the improvement of production and operation processes. Therefore, the implementation of zero inventory management will inevitably make enterprises always in the dynamic process of reducing inventory, finding problems and making continuous progress. (4) The implementation of zero inventory management requires comprehensive management technology. Zero inventory management is difficult to implement, it involves all aspects of enterprise procurement, production and sales, permeates every activity of the enterprise, and needs to integrate internal and external factors. Therefore, the implementation of zero inventory management requires enterprises to constantly explore and innovate in management, technology and production technology, and establish a set of management technology system suitable for enterprises.

Second, the importance of zero inventory management to modern enterprises

As an advanced management method, zero inventory management has greater potential than any marketing link, and its advantages are mainly shown in the following aspects: 1, which can reduce the capital occupation of enterprises, speed up the capital turnover and improve the efficiency of capital use. By adopting "zero inventory management", the enterprise's inventory on the same day is only for today's use, and it will never be purchased more, and the inventory at the end of each day will remain zero. In this way, the funds occupied by inventory are controlled to a minimum, which virtually increases the liquidity of enterprises. 2. It can reduce the storage cost and management cost of inventory. The storage cost and management cost of an enterprise account for a large part in the traditional inventory management system, and will eventually be deducted from the sales income of the enterprise, thus reducing the profit of the enterprise. Through zero inventory management, we can avoid these huge expenditures, thus solving the contradiction between management costs and benefits, and ultimately reducing enterprise costs and improving profits. 3. Promote enterprises to strengthen quality control and supervision. Quality is the life of an enterprise. If the product quality management is poor and there are many waste products and unqualified products, then zero inventory management will lose its meaning. "Zero inventory management" requires enterprises to attach importance to product quality, which provides a strong impetus for quality management. Haier is an example. Enterprises under traditional management purchase according to the production plan, because they don't know where the market is, they purchase for inventory. Haier is now implementing information management, opening these reservoirs through three JITs, and turning it into a flowing river that keeps flowing. JIT procurement is to purchase as much as needed according to the procurement plan of computer system. JIT feeding means that all kinds of parts are temporarily stored in Haier Stereo Library, then matched by computer, and the configured parts are directly sent to the production line. Haier has established a logistics center system all over the country. No matter where in the country, Haier can deliver goods quickly and realize JIT distribution. Inventory is not only a matter of capital occupation, but also a lot of bad debts. Nowadays, the upgrading of electronic products is very fast. Once the products are replaced, the prices of raw materials and finished products will drop sharply, and the only way out of the backlog of finished products is to reduce prices, so now there will be a price war in the market. Haier will meet the requirements of users with timely delivery time, and finally eliminate the space of inventory.

Three, the modern enterprise zero inventory management factor analysis

1. Stable business environment: Zero inventory of modern enterprises is only applicable to a relatively stable market environment. Because the order trend of small batch and multi-batch, personalized demand, unexpected events and other factors will cause demand fluctuation. At this time, although zero inventory reduces the inventory cost, it cannot meet the changing market demand, and the potential profit lost is far greater than the cost savings brought by zero inventory. 2. Suppliers: In order to ensure timely and accurate delivery, modern enterprises require suppliers to be within a certain distance. This is also convenient for enterprises to understand each other, exchange all kinds of information in time and provide timely after-sales service. If the supplier is abroad or far away from the province, and the supply is unstable, then there must be a "safety stock". 3. Supply chain management: If all members of the supply chain achieve zero inventory, the inventory cost will of course be reduced, but once a supply chain link breaks, it will hurt the whole supply chain. Zero inventory is not the ultimate goal of supply chain management, and the improvement of customer satisfaction or customer service level is the foundation for the survival and development of enterprises, rather than blindly pursuing zero inventory in the digital sense. 4. Information system: Now, market competition is no longer the competition between individual enterprises, but has risen to the level of competition between supply chains. The implementation of zero inventory in the whole supply chain must be supported by a good system, which can accurately and timely reflect the market demand (including software and management); There must be a procurement and flexible production system that can be quickly adjusted according to market information; There should be a coordinated logistics distribution system to make information transparent. Enterprises can reduce inventory and save inventory costs through information systems, thus gaining a competitive advantage.

Fourth, realize zero inventory management.

1, cooperative subcontracting mode

Collaborative subcontracting is an industrial structure of manufacturing enterprises, and several enterprises can supply goods on time flexibly, so that the supply inventory of the main enterprise is zero; At the same time, the centralized sales inventory of the main enterprise makes the sales inventory of some subcontracting services and sales enterprises zero. In many developed countries, the manufacturing enterprise is a pyramid structure composed of a large main enterprise and hundreds of small subcontractors. The main enterprise is mainly responsible for the guidance of assembly and product market development, and the subcontracting enterprises subcontract labor services, subcontract parts manufacturing, subcontract supply and subcontract sales. In practice, cooperative enterprises that undertake the task of manufacturing and supplying parts will generally arrange and adjust their production activities according to the production speed and progress of the main enterprise, and can deliver the goods in place within the specified time. For example, an enterprise that subcontracts spare parts manufacturing can take various forms of production and inventory adjustment according to the productivity of the main enterprise to ensure that the goods are delivered to the main enterprise within the specified time. Because the supply is guaranteed, the main enterprise will not set another level of inventory, thus making its supply inventory in a zero inventory state. At the same time, the main enterprise can use the centralized finished goods inventory of the main enterprise to meet the sales of subcontractors through quotas, on-demand contingency and other forms, so that the sales subcontractors can realize zero sales inventory.

2. Delegated storage method

Through certain procedures, the materials owned by the enterprise will be kept by a special company, and the enterprise will pay a certain custody fee to the trustee, so that the enterprise will no longer keep the inventory, thus realizing "zero inventory". The advantage of this "zero inventory" form is that the trustee can use its professional advantages to achieve high-level and low-cost inventory management. Enterprises no longer set up warehouses, and at the same time reduce a lot of warehouse and inventory management affairs, concentrate on production and operation, which embodies the professional characteristics and is the main trend of developing zero inventory in domestic enterprises at present. It is common to entrust a business warehouse to store and keep goods. Commercial warehouse is a kind of specialized and socialized warehouse. Entrusting such a warehouse or logistics organization to store goods, from the phenomenon point of view, is to store the goods owned by users in a highly specialized warehouse, which will keep and send the goods on their behalf, and the users will pay the service fee to the trustee according to certain standards. By storing and keeping goods in this way, in general, users don't need to store too much materials themselves, and they can even set up a separate warehouse to engage in activities such as the maintenance and keeping of goods, so as to realize zero-inventory and non-inventory production in a certain range.

3. Rational distribution mode

Distribution mode is a logistics mode that implements unified information management and scheduling for the whole logistics distribution system, carries out tally work in the logistics base according to the ordering requirements of the purchaser, and delivers the prepared goods to the purchaser. This advanced and optimized circulation mode can effectively reduce the logistics cost of enterprises, optimize inventory allocation and ensure timely supply, thus enabling enterprises to achieve "zero inventory". The specific methods are: 1, multiple batches and small batches. Around the needs of each user, enterprises make overall arrangements, carry out vehicle transportation, increase the number of deliveries, reduce the delivery volume of each user and each batch, and improve transportation efficiency. Distribution enterprises can also directly transport goods to workshops and production lines, thus making production enterprises in a state of zero inventory. 2, centralized inventory, through centralized inventory distribution of goods to users, increase the inventory and quantity of goods, form a scale advantage, reduce the cost of unit products, and at the same time, with the support of this guaranteed distribution service system, users' inventory will naturally weaken day by day. 3. Instant delivery. That is, the enterprise will deliver the goods produced according to the order to the users in time, and in this process, it will reduce the inventory by transporting the goods in transit and distributing and processing. Enterprises can realize the storage of goods in transportation by adopting standard JIT supply operation mode and reasonable distribution system, so as to realize zero inventory. The materials suitable for this supply form to realize "zero inventory" are mainly tools and standard parts.

4. Adopt timely and appropriate production methods.

Timely and moderate production mode is a management mode aimed at eliminating all ineffective labor, realizing the optimal allocation of enterprise resources and comprehensively improving the economic benefits of enterprises. The specific methods are: 1, production synchronization. That is to say, there is no warehouse between processes, and after the processing of the previous process is completed, it is immediately transferred to the next process, and the assembly line runs almost parallel to the processing, and the products are produced one by one. In casting, forging, stamping and other processes that must be mass-produced, the production batch should be reduced as much as possible by shortening the changing time as much as possible. In this way, the processes are collected layer by layer until the rough machining and raw material departments connect all the processes. 2. Balanced production. It means that when the assembly line collects the parts of the previous process, it should use all kinds of parts in a balanced way to produce all kinds of products. Therefore, it must be considered when making the production plan, and then it will be reflected in the product production sequence plan. In the manufacturing stage, equalization is achieved through the generalization of special equipment and the formulation of standard operations. 3. Management tools for timely and appropriate production. Kanban, as a management tool, is of great significance to realize timely and moderate production. Kanban management can also be said to be the most unique part of JIT production mode. Under JIT production mode, the monthly production plan is formulated centrally and communicated to various factories and cooperative enterprises. The corresponding daily production order only reaches the last process or assembly line, and the production orders of other processes are realized through kanban. Because it is impossible to produce according to the plan completely, the daily production and the modification of daily production plan are fine-tuned through kanban. Kanban is equivalent to the connection nerve between process, department and logistics, and plays a role. Through kanban, we can find the problems in production and expose them, so as to take immediate improvement measures.

Verb (abbreviation of verb) The realization of "zero inventory" management-supply chain management

Supply chain is a functional network chain structure that connects suppliers, manufacturers, distributors and retailers to end users by controlling the information flow, logistics and capital flow around core enterprises. "Zero inventory" is only the zero inventory of node enterprises, and from the perspective of the whole supply chain, products from suppliers to manufacturers finally reach sellers, and the inventory does not disappear, but is transferred between enterprises. In the environment of supply chain management, it is necessary to establish a supplier management user database if the activities of all links in the supply chain are to be carried out simultaneously. This inventory management strategy breaks the traditional scattered inventory. Suppliers can track and detect the inventory status of sellers at any time, so as to quickly respond to changes in market demand and make corresponding adjustments to the production status of enterprises. Start with the following aspects: 1, and establish the goal of * * * cooperation. First of all, it is necessary to establish a joint inventory management model, understand the similarities and conflicts between the supply and demand sides of the target market, and form the same goals through consultation, such as user satisfaction, profit growth, risk reduction, etc. 2. Establish a coordinated control method for joint inventory. The joint inventory management center plays the role of coordinating the interests of both supply and demand, and plays the role of coordinating controller. Therefore, it is necessary to clearly determine the method of inventory optimization. These contents include how to adjust and allocate the highest and lowest inventory levels among multiple demanders, the determination of safety inventory, the forecast of demand and so on. 3. Establish information communication channels or systems. In order to improve the consistency and stability of demand in the whole supply chain and reduce the distortion of demand information caused by multiple forecasts, it is necessary to increase the timeliness and transparency of demand information obtained by all parties in the supply chain. Therefore, it is necessary to establish an information communication channel or system to ensure the smooth and accurate demand information in the supply chain. It is necessary to integrate bar code technology, scanning technology, POS system and EDJ, make full use of the advantages of the Internet, and establish a smooth information communication bridge and contact link between the supply and demand sides.
