摘要
原油在线调合调度对于平稳混炼原油性质、保障先进控制的实施和优化炼油计划具有重要的意义。原油调合调度问题由于既包括顺序变量又包括连续变量,不存在明确的问题结构,复杂度高,传统的优化方法效率低,不能满足在线实时的要求。本文针对问题的两层结构提出了基于序的求解方案,利用实际原油性质数据的仿真结果表明,基于序的求解算法可以大幅度提高计算效率。
The scheduling problem of on-line crude oil blending is important to decrease the variation of the blended oil＇s properties, support the implementation of advanced control and optimize the refining plan. Because that sequential and continuous variables are interlaced, the scheduling problem of crude oil blending does not have an explicit structure, and its complexity is so high that the conventional methods cannot work real time. For the double-deck structure, an optimization scheme based on order was presented. By the simulation on the practical data of crude oil distillation range, the algorithm based on order could improve the computational efficiency significantly.
