A two-phase method for multi-echelon location-routing problems in supply chains

作者：

Highlights：

• Four location-routing problems are formulated as MIP.

• Tour length constraint of vehicles is considered.

• A two-phase method based on improved Clarke and Wright savings algorithm is put forward.

• The speed of this method is faster than that of other methods and is easy to be used and can be extended.
