摘要
针对可控提前期领域现有研究的不足,提出基于非线性提前期成本和存在顾客流失情形下,采用连续盘点策略的库存管理问题。证明当提前期需求服从正态分布时,存在唯一的全局最优订货量、订货点和提前期,使年总成本最小。本文给出有效的迭代算法求解最优解,并通过实例计算分析缩短提前期在库存管理中的作用。
According to the defects of the researches dealt with controllable lead time, the authors present a continuous review inventory model with nonlinear lead time crashing cost and lost sale, We proved there＇ s a global optimal policy which minimizes the expected total annual inventory cost when the lead time demand is normal distribution and develop effective iterative procedures for finding the optimal solution, Numerical examples are given to illustrate the effect of controlling lead time in inventory management.
