1. Vendor managed inventory strategy

This is VMI (vendor management)

Inventory) inventory management mode. Supplier management inventory strategy refers to the cooperation strategy between users and suppliers. Its basic idea is to try to reduce the overall inventory cost by integrating the inventory control functions of each node enterprise in the supply chain. Under this inventory control strategy, the upstream organization can plan and manage the inventory strategy and ordering strategy of the downstream organization. In the supply chain management environment, VMI has been widely used in inventory control.

The key to implementing VMI is to effectively implement continuous replenishment procedures. The strategy of continuous replenishment plan has changed the traditional way that retailers order from suppliers, and suppliers decide the replenishment quantity of goods according to user inventory and sales information. In order to quickly respond to users' requirements to reduce inventory, suppliers actively increase the frequency of delivery to users by establishing a partnership with users (distributors, wholesalers or retailers), which makes suppliers change from simply executing users' purchase orders in the past to actively sharing the responsibility of replenishing inventory for users, which not only speeds up the response of suppliers to users' requirements, but also reduces users' inventory level.

Vendor managed inventory can not only reduce the inventory level and cost of supply chain, but also enable users to obtain high-level service, improve capital flow, enjoy the transparency of demand changes with suppliers and gain better user trust.

2. Joint inventory management strategy

In practice, VMI management mode has brought great pressure to suppliers. On the basis of VMI, a new inventory management strategy, namely JMI (Joint Managed), is developed.

Inventory).

JMI is an inventory management model based on coordination center, which balances the rights and responsibilities of upstream enterprises and downstream enterprises and takes risks. JMI embodies the new enterprise cooperation relationship of strategic suppliers Alliance, and emphasizes the mutually beneficial cooperation relationship among supply chain enterprises.

Joint inventory management is an effective method to solve the demand amplification phenomenon caused by the independent inventory operation mode of each node enterprise in the supply chain system and improve the synchronization degree of the supply chain. Joint inventory management (/) emphasizes that all nodes in the supply chain participate at the same time, and the inventory plan is jointly made by * * *, so that every inventory manager in the supply chain can keep the expectations of inventory managers among all nodes in the supply chain consistent from the perspective of mutual coordination, thus eliminating demand variation and amplification, reducing inventory uncertainty, greatly reducing inventory, avoiding resource replacement and waste in the whole supply chain and improving the stability of the supply chain. The determination of the demand of any adjacent node is the result of coordination between the supply and demand sides. Inventory management is no longer an independent operation process, but a link and coordination center connecting supply and demand.

In the supply chain environment, to implement joint inventory management, we must first establish an effective coordination management mechanism. In the collaborative management mechanism, not only the supply and demand sides must establish the cooperative goal based on the principle of mutual benefit, but also the collaborative control method and information communication channel of joint inventory must be established on this basis. Secondly, we should play the role of two resource planning systems. Raw material inventory coordination management center should adopt manufacturing resource planning system (MRPII), and product joint inventory coordination management center should adopt material resource allocation plan (DRP). In the supply chain system, these two resource planning systems should be well combined. The third-party logistics system plays a bridge role between suppliers and users, and has gained a lot of benefits for enterprises. The third-party logistics system oriented to the coordination center makes the supply and demand sides cancel their independent inventories and focus on their core businesses, which increases the agility and coordination of the supply chain and greatly improves the user service level and operational efficiency of the supply chain.

3. Collaborative supply chain inventory management strategy

Supply chain inventory management strategy (cooperation plan forecast &; Replenishment), referred to as CP F.

This is the best grading practice based on VMI and JMI.

At the same time, it abandons the main shortcomings such as the lack of supply chain integration between the two, which can reduce the inventory of distributors and increase the sales of suppliers. The core of this management model is to adopt the win-win principle, always formulate unified management objectives and implementation plans from the overall perspective, take inventory management as the center, take into account other aspects of supply chain management, and apply a series of processing flows and technical models to cover the whole supply chain cooperation process.

By * * * managing business processes and * * sharing information, the partnership between distributors and suppliers can be improved, the accuracy of forecasting can be improved, and finally the purpose of reducing inventory, improving supply chain efficiency and customer satisfaction can be achieved. Its implementation strategies are: establishing customer information system, establishing sales network system, establishing cooperation framework agreement and reforming organizational structure. The biggest advantage of this management mode is that it can timely and accurately predict the sales peaks and fluctuations caused by various promotional measures or abnormal changes, so that both sellers and suppliers can make full preparations and win the initiative. Therefore, CPFR is more conducive to achieving broader and deeper cooperation among partners, and represents the development direction of supply chain inventory control.

4. Multi-level inventory optimization and control strategy

Joint inventory management based on coordination center is a federal supply chain inventory management strategy, which is the local optimal control of supply chain. In order to optimize and control the supply chain globally, multi-level inventory optimization and control strategy must be adopted.

Multi-level inventory optimization control is based on single-level inventory control. There are two methods for multi-level inventory control: one is distributed strategy, and the other is centralized strategy.

( 1)

Distributed inventory control strategy. Distributed inventory control is to divide the inventory control of supply chain into three cost decomposition centers, namely, manufacturing cost center, distribution cost center and retail cost center, and each center formulates an optimized control strategy according to its own inventory cost. In order to achieve the overall optimization of supply chain, distributed inventory control needs to increase the information enjoyment of supply chain, so that all departments of supply chain can enjoy unified market information. Distributed multi-level inventory control strategy can enable enterprises to make decisions independently and quickly according to their own actual conditions, which is conducive to giving full play to their independence and flexibility. The management of distributed multi-level inventory optimization strategy is relatively simple, but it can not guarantee the overall optimization of supply chain. It needs good coordination among enterprises. If coordination is poor and information enjoyment is low, it may lead to fragmentation.

Centralized inventory control. Centralized control is to put the control center on the core enterprises, which control the inventory of the supply chain system and coordinate the inventory activities of upstream and downstream enterprises. In this way, the core enterprise becomes the data warehouse in the supply chain, responsible for data integration and coordination. The goal of centralized inventory optimization control is to minimize the total inventory cost in the supply chain. Using centralized strategy, the control parameters of all inventory points are determined at the same time, and the relationship between inventory points is considered to obtain inventory optimization through coordinated method. The centralized strategy is more difficult to coordinate in management, especially when there are many levels in the supply chain, that is, when the length of the supply chain increases, coordination and control become more difficult.
