文中考虑了客户存在缺货现象和提前期对客户订货和生产商生产的影响,建立了供应链库存成本模型。该模型存在最优订货量、最优缺货量和最优订货次数,最后通过数值分析方法分析了最优值之间的关系。
Assumed that the shortage is permitted and the lead time can influence on both the customer and the manufacturer, the paper establishes the supply inventory cost model. It is proved that the model has the optimum order quantity, the optimum shortage and the optimum order times. Finally, the relationship between these three optimum parameters is discussed by the numerical analysis method.
