The treatment strategy of extinction materials is 1, and the electronic components of extinction materials produced by process changes and design changes are updated quickly. This is because of the development of science and technology or the change of policy, such as the introduction of ROHS directive, many substandard materials have been replaced immediately. The design and development department changes the company's products due to the needs of the process or customers. In case of change, the engineering change notice must be filled in, and PMC will confirm whether the materials are in stock or on the way. After receiving the engineering change notice, the purchasing department will immediately notify the relevant suppliers to completely stop the production of such materials. At the same time, PMC organized the Design and Development Department, Production Department, Marketing Department and ministry of materials and equipment to hold a meeting before filling in the dull material handling sheet to formulate the dull material handling measures. For the dull materials in stock after engineering changes, they should be reformed or replaced as much as possible in future development or production. 2. Dull materials caused by inaccurate forecast or order change. At present, the market is ever changing. Many manufacturing enterprises are order-based production methods, and their plans can't keep up with the changes in customer demand. When a customer changes or cancels an order, the sales department should immediately notify the Material Department and the Production Department, who will count the quantity of dull materials, including the quantity in stock, the quantity in process, the quantity in transit and the quantity outsourced. According to the statistical material cost, the sales department communicates with the customer at the first time and is responsible for recovering the compensation from the customer. PMC cancelled the order and sent out a warehouse withdrawal notice. The production department completes the delivery, and the warehouse fills in the sluggish material disposal form and sends it to the vice president or general manager for handling opinions. According to this opinion, the warehouse is responsible for temporary storage or scrapping. If it is because the sales staff is not accurate in forecasting, the company has ordered more or wrong materials, so it is necessary to improve the forecasting method. The rolling planning method adopts the principle of "near fine and far coarse" to revise the plan regularly, which is a good method, but it is not omnipotent. The key point is to predict the market demand through the historical sales data, operating ability, inventory situation and market changes of customers. Therefore, the account manager should strengthen the analysis of the customer's order progress, make relevant communication, supervision and guidance in time, ensure that customers can place orders according to the predicted quantity, and improve the order fulfillment rate and forecast accuracy. In addition, it is necessary to inform the account manager of the company's marketing strategy and daily inventory in time, ensure the blindness of the account manager in collecting market demand orders, actively forecast market demand, and constantly adjust the planning contract, so that the planning method gradually approaches the market method, and the market demand forecast is closer to the actual demand. 3. The marketing department shall immediately notify ministry of materials and equipment and the Finance Department of the sluggish finished products returned by customers. Ministry of materials and equipment is responsible for counting and warehousing the returned quantity and sending the confirmed quantity to the marketing department. If the goods need maintenance before they can be delivered again, PMC will arrange production maintenance, and the finished product warehouse will handle delivery, warehousing and delivery. If customers no longer order such goods, PMC should give priority to other customers' orders. If there is no digestible order, and the backlog exceeds three months, the materials department will fill in the dull material handling form and send it to the general manager for handling opinions, and the warehouse will be responsible for implementation. 4. The purchase allowance of dull materials caused by purchase allowance and safety stock is set by PMC and changed in time. For commonly used parts, wearing parts, common parts and materials with large price fluctuation, only purchase allowance can be set to supplement safety stock. PMC audits and checks the allowance and safety stock at least once a month, and the system data is accurate, which is the premise to avoid the sluggishness caused by excessive purchase or wrong materials. Purchase allowance and safety stock are not allowed for other materials. For such widely stocked or safe materials, we must follow the principle of first-in first-out, and give priority to material delivery. If the allowance and safety stock have not been digested and become dull materials, if the storage time exceeds six months, PMC will fill in the disposal form of dull materials and send it to the general manager for approval, and the warehouse will implement and file it accordingly. In a word, the generation of dull materials needs to be traced back to the source, so as to prevent and find dull materials in advance. Because of suppliers, it is also a way to strengthen the supervision and assessment of suppliers and send people to the factory to supervise the quality and delivery of materials; Because of the customer, we should negotiate with the customer. Signing an agreement with customers before purchasing special materials for them is one of the ways to avoid the sluggishness caused by customers changing or canceling orders. For the dull materials that have been produced, we should try our best to adjust and deal with them and minimize losses. The treatment methods are nothing more than disassembly, modification and reuse, such as shaping and re-electroplating. ; Substitute similar materials without affecting the function, safety and main appearance; Coordinate suppliers to return goods or even discount; Look for opportunities to transfer to other suppliers and customers (there are many companies to help deal with sluggish materials, including barter, profit sharing, consignment and so on. ); It's really bad, and it can be sold as waste.
