The rapid development of modern information technology, e-commerce has become an important weight of enterprises in the future market in its new business philosophy and implementation, and the information system has become an indispensable tool for enterprise management. Therefore, the implementation of the supplier management inventory not only involves its process, but also the implementation of its information support system. The use of information support systems has become an inevitable requirement for supplier management inventory implementation.
Internet-based supplier management inventory system
With the development of Internet technology, many companies have begun to do inventory management of supplier management inventory partners online. In the case where there are fewerly running Internet-based vendor management inventory systems, the most typical is a Global VMI system for universal electrical. Therefore, the operation of the Internet-based supplier management inventory system can be discussed by studying the operation of the Global VMI system.
Global VMI system of Universal Electric is an Internet-based vendor management inventory system. It combines information technology and sensing technology, Six Sigma (6 Sigma) data analysis to provide customers and suppliers with a cooperative management of supply chain services. Through this Global VMI system, the relevant parties on the supply chain can understand the inventory level in real time, and analyze the analysis of historical data and total amount of data through the system analysis function provided to smooth production and reduce inventory costs.
This system is originally developed to improve the level of customer service of Ge Plastics. It tries to improve its service level by monitoring GE Plastics's inventory level, while making your own supplier through the inventory of Ge Plastics. better. Subsequently, universal electrical uses this system, specializes in special storage methods for chemical enterprises. Enterprises can optimize their supply chain management by purchasing this system. Each user implements the management of the supply chain by entering the website of the Global VMI system.
The Global VMI system is composed of two application packages: a package provides some basic functions, such as inventory monitoring, setting the inventory level upper limit, providing the buyer and supplier query inventory, the web interface of the data of the entry and orders; another software Package provides complex planning and predictive tools.
Before using the Global VMI system, General Electric's supply chain analysts will discuss with the suppliers and manufacturers of the system. By consuming speed, raw material transportation mode, raw material transportation time, expectation in the information, etc. Study, use the Six Sigma method to determine the optimal inventory level of the inventory raw material and other replenishment programs in the inventory raw materials, and demonstrate the feasibility and effectiveness of the replenishment plan, and ultimately the determined replenishment plan input system.
After implementing the Global VMI system, each user can immediately understand the Global VMI website through their own account and password, and immediately understand the inventory level, including stock raw materials, inventory test time, etc. In general, the system is reported to the inventory level twice a day, and of course the user can choose more frequently in accordance with its own actual situation. This frequent monitoring is originally a dream of many chemical companies. Originally, these companies generally check the inventory level one to two times a week, and the method of checking is often climbed to the top of the storage tank down or tap the tank wall to judge the inventory, these methods cannot be accurately Measuring the inventory level and cost time. The Global VMI system uses sensing technology to enable computer systems to get inventory data in real time, and display them with visualization methods (Figure 3.9). The system is also specifically directed to some multinational requirements, and the monitoring function of global stocks is added. It offers an online world map labeled a global branch, each branch is displayed in different colors according to its inventory level, and green indicates that the inventory level is normal, and the red indicates that the inventory is too low, and the blue is more inventory. High, yellow indicates that you must order immediately. In this way, the supplier can immediately follow the inventory of the world at this point of view. The system provides detailed inventory analysis, gives daily, weekly and monthly dosage reports. The contents of the report include average dosage, maximum daily amount, minimum daily amount, and dosage fluctuation variance, users can adjust the replenishment plan in time. Users can also choose how to check the data. The person in charge of the factory may wish to understand the inventory level of each storage tank in the factory, and a regional manager may even understand the total inventory level of all the factories in the area he jurisdiction. AGGREGATE VIEW in the Global VMI system enables users with appropriate permissions to obtain any level of integrated data. At the same time, users can also choose to review the total amount of inventory of any time, inventory consumption curve. On the basis of data queries, the system is based on these data to predict future usage, and the user can also choose to make these prediction data into spreadsheet downloads to more carefully. In addition, the system allows the user to update forecasts based on sudden time. For example, if the feedstock is damaged during transport, the buyer can provide this information to the system. The system automatically updates the replenishment plan based on this latest situation, by changing the date of transportation of other raw materials, or increasing the number of other raw materials transportation, or when the raw material is added, the damaged raw materials are made.
The buyer and their suppliers can choose Automatic Shipment, that is, when inventory falls to a prior-prior fixed inventory excitation point (TRIGGER), the supplier automatically carries the buyer. However, if the buyer is willing, you can also ask the system to notify the buyer before the next order, and the supplier will take action after the order is recognized.
Supplier management inventory system based on enterprise resource plan
At present, many companies have implemented Enterprise Resource Planning, ERP, and enhanced corporate competitiveness through comprehensive information management. The Logistics Control and Logistics Plan is included in the sales and distribution modules of the ERP system. Enterprises who want to implement suppliers manage inventory systems can be modified by ERP systems, and the supplier management inventory system is developed. These standardized basic functions can be used as much as possible to reduce the changes to minimize changes to increase compatibility between the two systems.
The basis of the supplier management inventory system is the "consignment" ordering process in ERP. In order to achieve supplier management inventory, two major issues in the delegate order need to be modified: time and stock estimation method for payment. During the commissioning of the standard ERP system, the supplier is placed until the stock is placed, and the ownership of the stock will be transferred to the buyer and pay by the buying direction. In the supplier management inventory system, the supplier is only responsible for managing the buyer's inventory, but once inventory is transferred to the buyer's warehouse, the stock ownership is owned by the buyer, and the buyer should also pay supplied to the supplier. Another way to change is the inventory estimate. During the delegate order of the standard ERP system, the delegate library is for the supplier before being consumed, so suppliers must regularly evaluate their depreciation or value-added regularly to this part of the inventory, in order to reflect the company more truly in the financial statements. Stock value level. In the supplier management inventory system, there is no entrustment inventory. The supplier transferred the product to the buyer and also transferred the ownership of the product, so this part of the stock should not be re-estimated, and should not be reflected in the financial statements. But this part of the inventory data cannot be removed from the database because the supplier needs to identify this part of stock to determine the replenishment plan for the buyer. The method of solving this problem is to build a supplier management inventory database for this part of the transferred buyer's stock. When the product is transferred to the buyer, the data is classified into this database, and the inventory recorded by this database is not Do a valuation, this will not affect the correctness of the financial statements. Take the SAP R / 3 system as an example, Table 1 shows the R / 3 system and modifications made in order to implement the supplier management inventory system. Table 1: R / 3 system is doing the adjustment in implementing supplier management inventory
SAP R / 3 System Supplier Management Inventory System Entrusted Insured Replenishment Cargo Transfer When the Ownership does not transfer goods transfer time transfer buyer prompt payment buyer Tips payment inventory adjustment entrustment inventory and other stocks Association Database library data change is automatically modified by EDI inventory report by hand-input system inventory data.
Figure 1 shows the way to manage the inventory system for the Adjustment of the ERP system. The inspiration of this system operation is that the buyer consumes inventory, and the buyer will use the EDI inventory statement to the supplier to manage the inventory system report inventory changes. The system is modified by the report to modify the inventory data recorded in the inventory database, and stimulate decisions of replenishment order. According to the current inventory level, the ordering point and the minimum replenishment batch, the system decides whether to replenishment and supplement. This decision process can be operated by manual operation by means of a decision support system. In addition, the supplier management inventory system also takes into account the problem of replenishment delay. By checking the buyer's inventory to understand if the buyer receives a batch of replenishment. When calculating the next batch of replenished amounts, if the last batch of replenishment is delayed, the inventory in the way is taken into account. After the order is confirmed, it is sent to the buyer via EDI, and the goods are transferred and passed through the EDI prompt. The buyer needs to do is to accept the confirmed EDI order or modify the order.

The implementation of the entire supplier management inventory system can be done in three stages. The first stage is a conceptualization and definition phase. The supplier and buyer jointly develop system processes and determine the information required for implementing the system based on data in the original purchase process. This information includes parameters such as re-order points and minimum replenishment batch, as well as data such as inventory consumption and replenishment delay. Both sides also need to determine when these parameters are updated, how to update, when these data passes, how to pass. The second phase is the phase of the experimental facility. Suppliers can choose some product with lower recovery frequency to test whether the system can complete the entire replenishment process in accordance with the designed procedure. It can be technically possible to use a simple method. If you transfer data with email, use the spreadsheet to calculate the replenishment. The third stage is a comprehensive implementation phase. The supplier and the buyer modify the ERP system according to the test process, and establish a data transfer network to achieve a complete supplier management inventory system.
