一类带可变库存费用和短缺量延期供给的库存模型

An Inventory Model with Variable Holding Cost and Shortage Postponed Delivery

研究当库存费的变化率为存贮时间函数h(t)时,在允许缺货、缺货部分延期供给、拖后率为β(t)=e-kt,k>0,t是等待时间的情况下,易变质产品的最优策略。利用最小二乘法原理和泰勒展开分析了易变质产品最优策略的算法,并给出算例进行仿真。仿真结果证明了算法的有效性。

In this paper,when out of stock is allowed,and stock parts supply is deferred,the delayed rate is β（t） =e-kt,k ＞ 0,t is the waiting time.It studies the optimal replenishment and pricing strategy of a single perishable product.Using the least square method and the Taylor expansion,this paper analyzes the optimal order of perishable products and pricing strategies of the algorithm,gives examples and describes the simulation algorithm.
