This paper proposes a hybrid-time mixed integer linear programming model for low-energy scheduling of single-source multiproduct pipelines. The model divides the time horizon into slots by event points of batches reaching stations and fixed points of electricity price changing. Through this division, some practical factors are easily modelled as linear items, including time-varying electricity price and flowrate limits related to interfaces. The key technology for this model is the initialization of all time points’ sequence, so a decomposition approach is developed to efficiently seek satisfactory sequence of all time points. Its superiority is validated by two real-world cases.

针对单源多产品管道的低能耗调度问题，提出了一种混合时间混合整数线性规划模型。该模型将时间范围按批次到达电站的事件点和电价变动的固定点划分为时隙。通过该划分，可以将一些实际因素轻松地建模为线性项，包括时变电价和与接口相关的流量限制。该模型的关键技术是所有时间点序列的初始化，因此开发了一种分解方法来有效地寻找所有时间点的令人满意的序列。它的优越性已通过两个实际案例得到验证。
