连续聚合过程中牌号调度策略的研究

Study on Strategy in Coordinating Product Grades in Continuous Polymerization Process

基于工厂聚乙烯树脂牌号切换产生废料量的设计值,建立了废料量的预测模型,其误差仅为10.45％(均聚牌号)和5.07％(共聚牌号);并提出了以赢利与否为依据的牌号切换判断模型。

Based on the design value for polymer reject produced during grade transition period in polyethylene plant, this paper established a model for predicting the reject ratio, with average error of 10.45% for homopolymer grades and 5.07% for copolymer grades. In addition, a criterion model for selecting grades was presented, judging from whether the grade being able to make profit or not.
