In this paper , the periodic vehicle routing problem with intermediate facilities , i. e. waste transfer stations , was analyzed. There are two kinds of vehicles , collection vehicles and transportation vehicles , and some transfer stations in the system. The collection vehicles can renew their capacity at the transfer stations , where the transportation vehicles can get the waste container. The objective of this paper is to combine the location of the transfer station and the vehicles routing into a mathematical model , which is called PLRPIF model , to minimize the system operation cost. And a twophase Tabu search algorithm was developed to solve this model. Finall
