研究了电石法制聚氯乙烯(PVC)全流程生产调度问题,包括从电石生产、盐水电解到氯乙烯(VCM)聚合产品出厂各环节,其中电石生产和 VCM 聚合是间歇过程,其他生产环节是连续过程,是一个混杂系统调度问题。本文针对过程特性对该问题进行了合理假设,以包括电耗、库存、产品型号切换、交货延迟等的成本最小为目标,建立了基于离散时间表示的混合整数线性规划(MILP)调度优化模型,并针对一个案例进行了调度优化求解和分析,验证了模型的可行性。

The overall process scheduling problem of polyvinyl chloride (PVC) production by calcium carbide method is studied in this paper, which is a hybrid system involving all production sections from calcium carbide production process and brine electrolysis process to polymerization of vinyl chloride (VCM). Calcium carbide production and VCM polymerization are batch processes, while other processes are continuous ones. Two hypothesis are made based on the process characters. Then the cost of electricity consumption, inventory, changeover and delivery delay is considered as an optimization objection, and the mixed integer linear programming (MILP) model of scheduling is constructed. The model is validated by a case of a PVC plant and comparing with the model with constant productivities of continuous stages.
