SYSTEM FOR RETURNING MATERIALS

PURPOSE: A system for returning materials is provided to maximize a return efficiency of the materials by efficiently allotting a work to a return car, searching an optimal path with use of various time information, and reflecting a situation of the return path in real-time. CONSTITUTION: A host(3) transmits a work command. A work command manager(4) orders the work by receiving the work command transmitted from the host. A work allotting part(10) generates work allotment information based on the work command, and transmits the information to a path searcher(12) and the work command manager. The path searcher generates path search information by searching the path depending on the work command, and transmits the information to the work allotment part and the work command manager. A work command executer(6) transmits the information received from the work command executer to a return car interface(8). The return car interface makes the return car perform the work information by receiving the information transmitted from the work command executer.
