Summarize the main progress of research on Location-Routing Problem and the advance of optimal algorithm of LRP, give a comment on the research progress of LRP optimization algorithm and its characters, at last focus on putting forward some important development direction in this field. The optimal algorithm for the problems of LRP including location-allocation problems(LA),vehicle routing problem (VRP),and location-routing problem (LRP)were compared and contracted. Some possible paths for further research in this field were presented. analyze a few characteristics of the methods proposed to solve LRPs and present some issues for further investigations in this field.
