Evaluation method of effect of marshalling operation process based on DEA

Based on the marshalling station transfer operation process, this paper divides process into three sub-processes: arriving-disintegrating, disintegrating-marshalling and marshalling-dispatching. Considering input of facilities station, intermediate output operating time final number trains, an evaluation index system is constructed a slacks-based network DEA model established. For purposes illustration, applied in design calculation example, efficiency analysed, results show that effective.
