3. What are the network structure patterns of the cold chain logistics network?

The first layer is the purchasing end, the second layer is the distribution and logistics center end, and the third layer is the store closest to the user.

The traditional logistics system is centralized, and Box Horse is decentralized. One of the chilled products, 0 to 4 temperature requirements are very high, a little fluctuation, the quality will change, so it is difficult for B2C to do this, so the decentralization of the box horse so that the goods are close enough to the user, with 30 minutes 3 axiomatic limit, hot and cold chilled can be done.
