Abstract: Compared with the traditional railway, the layout of the railway in the metallurgical enterprises exhibits a planar distribution and it has a wide variety of goods transportation. Moreover, the transport path of the railway in the metallurgical enterprises is not a single option and its timeliness is important. This paper studies the real-time collaborative optimization of the multi-train route in the metallurgical enterprises and proposes a train route control optimization strategy. This strategy is constructed by a time-varying railway network topology, a train route control evaluation function which has the shortest transportation time and the best real-time performance, and also by the realization of the real-time collabo-rative optimization of the multi-train route on the basis of the dynamic programming. Meanwhile, it constructs the strategy in the self-developed computer interlocking system for steel factory. The running example indicates that it can be directly applied in the internal railway of the metallurgical enterprises and automatically realizes the real-time collaborative optimization control of multi-train route to ensure the high efficient cargo transportation.
