System-dynamics-based emergency transportation strategy analysis for oil products

Emergency transportation for oil products (ETOP) is the important content for guaranteeing emergency materials in emergency response phase. The paper researched main factors influencing efficiency of ETOP based on system dynamics. ETOP was divided into four cases, including pipeline transportation, railway transportation, road transportation and waterway transportation in terms of mode of transportation, and the system dynamics model of ETOP was built. Simulation verification was applied using China National Petroleum Corporation's ETOP during the Wenchuan Earthquake in 2008. The research illustrates: in the process of ETOP, oil companies could augment pipeline transportation rate effectively by promoting oil pipeline security capacity; oil companies could enhance railway and waterway transportation rates effectively through the government's planning and coordination, strengthening communication and coordination with railroad and waterway apartment; applying the three emergency transportation strategies above could greatly improve ETOP capacity. Furthermore, increasing road transportation rate, could be an alternative strategy, although it could not significantly enhance ETOP capacity.
