However, the establishment of safety stock is bound to make the cost of business increase, after studies show that the safety stock in the logistics field cannot continue to increase down needs and logistics, logistics and speed limit orders supply chain into account, only in this way, the field of logistics safety stock is the most effective method of logistics.展开更多
