有几种定义可选：

1、物品从供应地到接收地的实体流动过程，根据实际需要，将运输、装卸、搬运、包装、流通加工、配送、信息处理等基本功能实施有机结合。

2、The Definition of Logistics
物流的定义
After completing a commercial transaction, logistics will execute the transfer of goods from the supplier( seller) to the customer( buyer) in the most cost-effective manner. This is the definition of logistics. During the transfer process, hardware such as logistics facilities and equipment( logistics carriers) are needed, as well as information control and standardization. In addition, supports from the government and logistics association should be in place.
在完成商业交易之后,物流将以最低成本和最高效益的方式执行将商品从供应商(卖方)流转到顾客(买方)的过程。这就是物流的定义。在物流过程中,既需要诸如物流设施和设备(物流运输工具等)的硬件,也需要对物流实施信息化管理进行物流标准化。此外,政府和物流组织的支持也不可或缺。
