摘要
以对象和事件为基本方式构建原油调度系统。其中,对象是指油轮、码头罐、装置罐、原油蒸馏装置(CDU)以及各连接管线,事件则是作用在这些对象上的收油、送油操作,这些事件相互作用,构成了原油调度的事件驱动模型。采用约束规划方法对模型中的变量和约束进行描述和求解。通过模型在实际原油调度的应用,得到了连续时间段的原油调度结果。从结果可以看出,约束规划的原油调度模型对包含连续变量和整型变量的混合模型可较快地求出可行解,并且对于调度过程非线性指标的控制取得了良好的效果。
system, unit） ; E event-dri Scheduling of crude oil can be described the objects include oil vessels, storage ta as a system made up nks, charging tanks of objects and events. In the and CDU （crude distillation vents can be used to describe the oil transfer operation taking place on these objects. The ven model for scheduling of crude oil bases on these events in which variables and constraints are described with CP method. Via applying the model in oil scheduling, the continuous scheduler solution can be obtained. As a result of the solution, constraint programming model of crude oil scheduling can deal with the mixed model including continuous and non-continuous variables quickly, and control the nonlinear variable in the model easily.
