The method can reduce the rationality of the selection. The current location selection by gravity method mostly studied the logistics center location problems without any limitations. Running and building expense could be reduced greatly by selecting appropriate address of logistics distribution center.

Logistics distribution center is an important part of modern logistics system. Sur La Fonction Exponentielle.- And much more.
