摘要
针对需求信息未知的情形,建立了单周期具有单向可替代性的两产品在线订货报童模型,设计了有效的在线订货策略并进行竞争分析,给出了该问题的最优竞争比以及对应的最优订货量。最后通过对相关算例的分析,表明本文所设计的在线策略具有合理性和有效性。
The newsboy problem has always been an important issue in inventory management.The exiting substitutable newsboy models always describe and measure demand with probability and distribution function.However,in reality,it is often difficult to exactly characterize the demand.This paper considers the online newsboy problem with one-way substitution and unknown demand information.It presents an online order strategy for this problem with a matching optimal competitive ratio.The numerical example demonstrates that the strategy is reasonable and effective.
