摘　　要：针对原油在长输管线输送过程中伴有原油延迟离开管线的情况,提出一种新的基于连续时间的原油调度数学规划模型;并以中国A企业原油储运问题为例,利用该模型可通过监控原油在长输管线中的移动状态,推测其离开管线的时间,通过数学方式描述管线“平推流式”输送过程。模型方案测试结果表明:所建模型的规模较小,具有较强的计算求解性能;采用该模型可在3 min内优化出为期240 h的优化原油调度方案,最大程度地稳定原油蒸馏装置生产和避免油轮滞期。A novel mathematic programming model of crude oil scheduling based on continuous time was proposed to solve the problem of delayed departure of crude oil from long-distance pipeline.Taking the problem of crude oil storage and transportation in enterprise A of China as an example,this model can be used to monitor the movement of crude oil in long-distance pipelines,predict the time of its departure from the pipeline,and mathematically describe the pipeline“flat push-flow”transportation process.The test results of the model scheme showed that the proposed model was small in scale and had strong computational performance.The optimized crude oil scheduling scheme with a period of 240 h could be optimized within 3 min by using the model,to maximize the stability of distillation unit production and avoid tanker delays.
