Abstract

Abstract: In China's comprehensive transportation system, railway is an important mode of transportation, and heavy-load railway is a large-capacity transportation channel, which can quickly improve efficiency and relieve the capacity of railway transportation. The efficiency and synergistic capability of each connecting point of heavy-haul railway determines the success or failure of the whole system. In this paper, two different maintenance modes, "planned repair" and "unit centralized repair", are used to discuss the turnround procedure of rolling stock and the empty wagon's operation procedure respectively. The Petri net model of the empty wagon's operation procedure under different maintenance modes is established, and the simulation is completed by Visual Object Net++ software. The results show that "unit centralized repair" is beneficial to compress the operation time and accelerate the turnround of rolling stock.
