然而经典的生产库存模型并不考虑容量可变性，而是假定机器在单位时间内的生产量是恒定的常数。
However, the classical production inventory models do not take volume flexibility into account, machine production rate is usually assumed to be a constant.
在一般的供货商与销售商联合生产库存模型中均做如下假定：在一个生产周期内任意连续两次供货量之间的比值是相同的。
In the general vendor-buyer integrated production inventory models, there exists a common assumption that the ratio between two successive shipments within a production cycle is the same.
基于短缺量部分拖后的EPQ模型，考虑需求随时间指数增长以及缺货和现货期间生产率不相同对库存管理补充策略的影响，建立了相应的生产库存模型。
Based on the classical EPQ model, this paper develops an EPQ model for deterioration items with different lost sale factor relative to the inventory level during shortage period.
供应链系统允许生产期间订货，从而将库存模型一般化。
Orders in production period, are allowed m supply chain system, so inventory model is generalized.
