摘要
建立了短缺量完全拖后情况下,变质物品在存货影响销售率、理论销售率为常数且使用[s,S]策略补充库存时的利润模型;应用最大值原理和最优脉冲控制理论,确定了最优订购时间点,使经营周期[0,T]内的利润最大化;并通过算例仿真进行了实证研究。为存贮管理决策提供了理论依据。
Under the assumption of stock dependent selling rate, constant rate of theoretical demand, shortage backlogging completely and replenishing the inventory by [s, S] policy, the profit model is proposed. With the aid of maximum principle and optimal impulsive control theory, the maximal profit is obtained by establishing the optimal ordering point during operating duration [0,T]. Then a case and simulation is given to qualify the method. The theoretical evidence is provided for the inventory system to make management decision.
