基于确定型的可替代产品单周期库存模型已有研究,它假定替代数量关系是确定的.而事实上,替代过程中由于消费者需求的个性化因素影响,替代的数量关系往往是随机的.为此,假定替代数量关系符合随机分布条件下,提出了两类可替代产品的单周期库存模型,并设计了基于遗传算法的仿真优化算法.算例分析的结果表明,考虑随机替代关系可显著地提高决策者的收益;该算法是有效的.
基于確定型的可替代產品單週期庫存模型已有研究,它假定替代數量關繫是確定的.而事實上,替代過程中由于消費者需求的箇性化因素影響,替代的數量關繫往往是隨機的.為此,假定替代數量關繫符閤隨機分佈條件下,提齣瞭兩類可替代產品的單週期庫存模型,併設計瞭基于遺傳算法的倣真優化算法.算例分析的結果錶明,攷慮隨機替代關繫可顯著地提高決策者的收益;該算法是有效的.

The single-period, substitutable inventory model., based on the hypothesis that substitution's quantity relationship is deterministic, has been studied a lot.However, due to effects of consumer demands' personalization, substitution quantity relationship is always stochastic.Considering stochastic substituting relationship between two terms, a single-period-two-substitution inventory model is proposed and a simulation optimization algorithm based on genetic algorithm is designed.Results indicate that the profits can be obviously improved considering stochastic substituting relationship and the proposed algorithm is efficiency.
