How to classify ABC of goods? How to ABC classify products

From commercial (EIQ analysis) and logistics (inventory turnover.

On the contrary, low-value goods with unsalable goods with low inventory turnover rate are classified as Class C products, and Class B products are classified as Class B products in between. ABC classification is the result of the analysis and comparison of inventory goods, and the proportion of each type of goods is managed by the enterprise according to the sales policy and inventory.

The strategy is formulated, usually Class A products account for 15%-20% of the total commodity varieties, Class B products account for 30%-40% of the total commodity varieties, and Class C products account for 60%-70% of the total commodity varieties. The ABC classification of commodities is not static, and with the changes in the market and the change of sales policies, the ABC classification of commodities is also adjusted. The ABC classification of goods can be used as the basis for the space planning of the warehouse in the logistics center.

From the convenience and efficiency of picking and shipping, the general principle is that Class A products with high inventory turnover rate are stored in storage locations close to the shipping area (shipment inspection and delivery) and easy to access (close to the bottom shelves and convenient picking), while Class C products are stored on the shelves far away from the shipping area and at a high level.

In the actual case, a large logistics center, a wide variety of commodity items, if according to a variety of a location storage, the required number of storage locations is very large, usually a fixed area is planned for the storage of class A products, in the area of all the storage locations can only store class A products, we call it a class area. Similarly, Class B and Class C areas are divided for Class B and C items for storage use. If the warehouse has multiple floors, the Class A area is on the first floor, and the B and C areas are on the second floor or higher.

Small and medium-sized logistics centers, limited by warehouse space, provide a limited number of picking storage locations, according to the commodity ABC classification of the plane partition is of little significance, at this time the storage space can be three-dimensional. If the storage shelves are three-dimensional multi-layer shelves, close to the bottom layer (such as.

The first and second floors, easy to access and pick goods) are assigned to the storage and use of class A products, and the storage locations of the high-rise are used for class B and C products in turn, so that the planning is convenient for inventory management, and also makes the shelf and picking operations efficient and convenient.

If the relationship between commodity ABC classification and commodity storage space is fully considered in logistics planning, then in the WMS system, the principle of assigning storage locations for inbound commodities is closely related to commodity ABC classification. Class A commodities need to be assigned to the storage location partition or storage location with Class A attributes of Class A commodities, and the same principle applies to category B and C commodities. Through the association between the ABC classification attribute of the product information and the ABC partition attribute or ABC category attribute of the storage location, the system can find the correct storage location for the inbound goods to be put on the shelf.

The products are divided into class A according to quality, the first 10% can be divided into class A, the next 20 can be divided into class B, and the rest can be divided into class C products. Class A goods: the proportion of varieties is about 10%, which accounts for a small proportion; However, the proportion of the amount consumed annually is about 70%, which is a large proportion and is a key minority that needs to be managed.

Category B goods: the proportion of varieties is about 20%; The proportion of the amount of annual consumption is about 20%, and the proportion of varieties is basically the same as the proportion of the amount, and conventional management is sufficient. Category C goods:

The proportion of varieties is about 70%, accounting for a large proportion of bent wang; However, the proportion of the amount consumed annually is around 10%, and the number of such items is too large to take up a lot of management costs, but the amount of annual consumption is very small, and only general management is required.

ABC material classification method will be divided into ABC three categories of management objects, the characteristics of these three types of materials are as follows: A type of materials: high price, less varieties of materials, the type of total material types accounted for about 10%, and the purchase amount accounted for about 70% of the total material purchase amount, should be re-debated loose fiber point management control.

Formulate material requirements planning according to the production method to reduce inventory to a minimum. Class B materials: materials with higher value and less variety, the types account for about 20% of the total material types, and the purchase amount of imitation accounts for about 20% of the total material purchase amount, which should focus on management and control.

According to the production mode to formulate the material demand plan, the inventory control within a certain range can be strict. Class C materials: materials with low value and many varieties, the types account for about 70% of the total material types, and the purchase amount accounts for about 10% of the total material purchase amount, and the conventional management control can be.

Both Class A and Class B products are categories of stationery and educational supplies.

Class A: office culture and education, keyboard and mouse, camera, headset, projection screen, backgammon machine, radiation protection clothing, binding machine.

Category B: Office consumables (except copy paper), office equipment, conferences**, printers, scanners, projectors, digital products, mobile storage, network equipment, office furniture (except filing cabinets), daily necessities.

The original term "A and B products" is the classification of Nike and other companies, and it is just a division of quality.

Later, Class A and Class B goods are classified as stationery and educational supplies X0DA category: office culture, keyboard and mouse, camera, headset, projection screen, backgammon machine, radiation protection clothing, binding machine. x0db class:

Office consumables (except copy paper), office equipment, conferences**, printers, scanners, projectors, digital products, mobile storage, network equipment, office furniture (except filing cabinets), daily necessities.

1 The concept of ABC management methodABC management method, also known as the key method, is a scientific method for analyzing economic activities and strengthening management. It is widely used to improve various management activities, the effect is very significant, is one of the main contents of enterprise modern management. ABC management method is based on the main characteristics of the management object in terms of technology and economy, which is classified and queued, divided into key, secondary and general, that is, the management object is divided into three categories of ABC, in order to distinguish and determine different management methods of a scientific management method.

At its core and essence is the "critical minority vs. the minor majority".

2 Classification principles and standards of the ABC management lawIn the management of grain and oil storage, the object of the ABC management method is the expenditure of various storage costs.

According to the basic principle of "critical minority and minor majority", the analytical factors (i.e., various expense items) are divided into three categories of ABC. Category A: Critical Factors, also known as Major Factors.

Category B: Minor factors. Category C:

General factors. Its classification criteria can be summarized as ABC classification standard table After the management objects are divided into three categories of ABC, it is not the implementation of key control for all items in category A, nor the implementation of secondary control and general control over category B and category C items.

The scientific method is to decompose the original projects in the three categories of A, B and C, and then divide the projects in each category into three layers: A, B and C, so as to form a layer-by-layer focused management method. The stratification uses a scoring method to score projects according to their expenditure, value, service life and importance. Category A:

The dosage is large, the value is high, the service life is short, and the total score is 80 100 points; Category B: between A and C, with a total score between 60 and 80; Category C: Average expenses, low value of items used, long service life, total score below 60 points.

What, you didn't make it clear.

The classification of class A, class B and class C dimensions of products belongs to the quality characteristics of the product.

Quality Characteristics Importance Rating: A rating based on the degree to which a quality feature affects the suitability of a product.

Quality Characteristic Importance Classification Hierarchy Rules.

1.It directly affects the safety of the product or seriously affects the performance, life and characteristics of the product, and cannot be repaired after the out-of-tolerance, which is a key feature and the level symbol is A.

2.The quality characteristics that affect the performance and life of the service, the degree of influence is large, it is an important feature, and the level symbol is B.

3.The quality characteristics that have little impact on the performance and life of the service, and the degree of influence is small, which is the general characteristics, and the level symbol is C.

Specific requirements can be found in the standard JB T5058-2006
