论文摘要
我们解决了针对化学厂操作的具有挑战性的坦克混合物和调度问题。我们将问题建模为非Convex MIQCP,然后使用基于离散化的方法将该模型近似为MILP。我们将滚动范围方法与单个化学财产规格的离散化结合在一起,以处理长期计划范围,随时间变化的质量规格以及具有离散到达时间的多个供应商。已经使用专业化学工业的行业代表性数据集对该方法进行了评估。 我们证明所提出的方法支持快速计划周期。
We address a challenging tank blending and scheduling problem regarding operations for a chemical plant. We model the problem as a nonconvex MIQCP, then approximate this model as a MILP using a discretization-based approach. We combine a rolling horizon approach with the discretization of individual chemical property specifications to deal with long scheduling horizons, time-varying quality specifications, and multiple suppliers with discrete arrival times. This approach has been evaluated using industry-representative data sets from the specialty chemical industry. We demonstrate that the proposed approach supports fast planning cycles.
