With the domestic epidemic situation improves, companies across the country are in a fully resumed resume production stage. Enterprises return to work first thing to do is to inventory their goods inventory, inventory understand the current situation, develop appropriate procurement strategy for the follow-up sales. Inventory refers to the number of currently unused, and, economically valuable resource for the future. Inventory is to prevent production interruptions, stable operation, ordering cost savings, improve service quality, prevent shortages. Currently the vast majority of enterprise supply chain model used is that "push" supply chain or "push - pull" type of supply chain, inventory has become a focal point in the product distribution process inevitable.
Whether excess or insufficient inventory, it will cause some impact on the business, so companies in the supply chain problems in the end should be most concerned about is how much storage inventory? Inventory should be stored where? When do I need to replenish inventory? It is more inventory optimization problem solved. If the company can use inventory optimization to find the answer to three questions above, you can develop it to production, transportation and procurement plans, so that the entire supply chain efficient operation.
Inventory Optimization significance is a reasonable position inventory, so that precise replenishment, to achieve at the same time reducing capital employed, under the premise of limited resources to achieve service levels and optimize customer satisfaction.
☞ common method of inventory optimization are as follows:
01, ABC classification
ABC classification is mainly based on the main features of things in technical and economic terms, the product of class division. ABC classification rules is relatively simple, the main basis for classification of financial occupancy rate is in stock.
Class A stock need to calculate the economic order quantity and reorder point for each item, and appropriately increase the number of order as far as possible, in order to reduce the backlog of inventory, which is to reduce its high storage costs and large amounts of funds used. Class B stock also need to calculate the economic order quantity and reorder point, but need not be as stringent as the requirements of Class A, as long as the regular general check on it. Class C stock due to the large number of products, but the unit price is very low, and lower inventory costs, and therefore, can be appropriately increased the number of each order, reduce the number of orders throughout the year, daily control methods such materials, generally can use some more simplified "double box method" for management.
ABC classification in terms of inventory control, procurement strategy, storage, and other management priorities deeper planning, it is possible to optimize the inventory management is more reasonable. However, due to the procurement lead time, procurement extent, supply-side factors such as the strength is not considered, and therefore does not have comprehensive.
02, quantitative ordering method
Quantitative ordering methods means that when stocks fell to a predetermined minimum stock number (reorder point), according to a prescribed number (EOQ general economic quantities as a standard) carried out a supplementary orders inventory management.
If demand and order is established, without the need for safety stock, reorder point can be determined based on lead time and year-round demand. If demand and orders are not clear, the need to consider the case of safety stock, reorder point can be determined based on average demand, lead time and maximum safety stock.
EOQ is to achieve the lowest total cost of inventory quantity orders, it is ordered by balancing costs and storage costs get both, according to order quantity required, to determine the cost per order.
Quantitative ordering method advantage of simple operation, an effective amount of work savings, cost savings and reduced inventory costs. But the law is not flexible ordering, take up a lot of manpower and resources, and therefore only applies to independent inventory management needs.
03, regularly ordering method
Management regularly ordering method is a method by ordering pre-determined time intervals in order to replenish stocks. Its principle is a predetermined maximum stock levels and order cycle periodically check stock, according to the highest inventory, physical inventory, orders and order quantity in transit quantity library number of items, to be calculated each time an order making instructions, tissue orders.
Periodic Order Act no fixed order quantity, order quantity of each cycle is determined by the size of the size at the time of actual inventory amount equal to the difference at the time of actual inventory and the highest stocks. Maximum levels regularly ordering method is the use of average demand, the procurement cycle, procurement lead time, to determine the safety stock, and order cycle using a single ordering costs, storage costs per unit of product per unit time to stock demand definite.
Periodic Order Act advantages can be shipped together, reducing order costs; cycle counts more thorough, accurate, reducing the workload, storage efficiency is improved; planned inventory management is strong, the arrangements for the storage plan is very beneficial. The disadvantage is that safety stock can not be set too low; the demand deviation is large; poor economy.
There is an inventory management company the following questions: inventory takes up a lot of money; amount of inventory and more lead to excess inventory. How to optimize inventory analysis? Be analyzed from the amount of inventory and inventory number:
Also in the inventory optimization according to the inventory trend forecasting intelligence inventory changes, as shown on the lead time of 7 days below safety stock of 150 products early warning. It can be timely replenishment through intelligent early warning, to provide customers with better service.
According to the above, inventory optimization can help companies master inventory status, control inventory levels, reduce capital occupation, improve efficiency, reduce inventory sluggish, improve inventory turns, but also to grasp the status of goods to avoid losses expired.
Conform to the trend of the era of big data, inventory optimization through more efficient use of resources, supply chain logistics, business flow, information flow for all aspects of the supply chain, enabling enterprises, help enterprises more rapid growth.
