本文提出了建立月度生产计划模型的方法。着重解决确定月末库存变量在目标函数中价格系数的问题。为了使库存量维持在最佳范围,本文引进了非线性函数线性化的方法——λ法。此外,本文还提出了双月联合调优的模型。天津炼油厂根据这些方法,建立了月度生产计划模型,实际应用表明是可行的。
This paper presents a method of establishing a monthly production plan model. Focus on solving the problem of determining the price coefficient of the end-of-month inventory variable in the objective function. In order to keep the inventory in the best range, this paper introduces the method of λ - linearization of nonlinear functions. In addition, this article also proposed a bimonthly joint tuning model. According to these methods, Tianjin Refinery has established a monthly production plan model, which shows that it is feasible.
