Abstract: Southwestern product pipeline, SINOPEC, has formed a new operation mode with 2 oil sources (in Maoming and North Sea areas) transporting oil products by expansion. The previous batch scheduling algorithm and software which is aiming at single oil source transporting mode is not suitable any more. Based on batch scheduling algorithm which is suitable for pipelines of multiple oil sources, and mature multiple oil sources pipeline scheduling theory, combined with factors which should be considered during the making of domestic product pipeline scheduling plan, the paper develops commercial batch scheduling software, solving the problem in branch line of oil transport coordination and the problem in the intersection point injection transfusion site distribution operation mechanism in double oil sources mode. The software developed has been used in making daily scheduling plan of the southwestern double oil sources product pipelines, improving the work efficiency of the making of scheduling plan significantly.
