Abstract: By considering the environmental protection,we established bi-level programming models in which the government is in the up-level and the followers are logistics enterprises to study how the government and the logistics enterprises laid down measures to not only protect the environment,but also reduce the cost of logistics enterprises,i.e.,to seek the relatively optimal decisions for both the government and the logistics enterprises.

Key words: distribution centers, location decision, bi-level mathema tieal programming model, ewironmental protection
