Logistics optimization based on time window class research paper is more, such as: till the time window of the vehicle routing problem optimal solution ", "the customer time window and emergency vehicle scheduling shipments change research, and the time window constraints of full vehicle optimization scheduling algorithm research, interested readers can again in the Intranet search related thesis of" Chinese periodical net "further study.
