It can give full play to the role of economic batch, reduce inventory costs, save costs and improve economic benefits; 4, can often grasp the inventory dynamics, timely order when needed, and it is not easy to be out of stock.

Disadvantages: 1, inventory must be counted frequently (with the application of inventory management information system, this problem can be better solved), occupying a certain amount of manpower and material resources; 2. The ordering time cannot be determined in advance, and it is difficult to make a careful purchasing plan, which is not conducive to the planned arrangement of personnel, funds and work business; 3. Limited by a single order, it is difficult to achieve a multi-variety joint order, and it is also impossible to get a discount on the consolidated order.

Advantages of conventional ordering method: 1, multiple materials can be ordered together, reducing ordering and transportation costs; 2. You don't need to take stock every day, just take stock when it is due; 3. With the ordering cycle, it is convenient to make plans according to this cycle.

At this time, there may be shortages.
