研究了易变质产品的可替代库存模型.在有限计划期内,供应商面临两种不同产品的需求,当一种产品发生短缺时,另一种产品可以以一定的替代率代替短缺产品.通过分析系统的总成本函数的性质,提出了最优订购策略.最后通过算例验证了算法的最优性.
A deteriorating items inventory model with substitution is proposed in this paper.In a finite-planning horizon,two products with different deterioration rate are replenishmented by supplier.The shortage for one product is allowed in this model and it may be replenished by the other item with the fixed substituting rate.By analyzing the properties of total cost function,the optimal replenishement policy is established.Finally, numerical examples are given to illustrate the theoretical results.
