供需不确定情形下基于期权的血液供应链优化

在供需不确定决策环境下,构建了基于期权的血液供应链决策模型,通过对模型的优化分析,以期揭示期权合约和供需不确定对血液供应链的决策影响.首先,在供需不确定和期权合约下,分别得出了医院的最优血液产品的采购策略(包含血液产品的最优常规采购量和最优期权采购量),以及血液中心的最优血液采集和生产策略.其次,将血液供应链在分散和集中决策下的策略进行比较,得出了实现血液供应链协调的合作条件.该协调条件不包含血液产品的采购价,只依赖于血液产品供应特征的影响.最后,论文证明了在血液供应链协调时,存在一种可以实现帕累托最优的供应链合作方案.

Optimization of blood supply chain with option contracts under supply and demand uncertainty

Under supply and demand uncertainty, this paper develops blood supply chain models that incorporate option contracts. And this paper provides insights into the effect of the option contracts and the supply and demand uncertainty on blood supply chain decisions. Firstly, under supply and demand uncertainty, we derive the hospital's optimal procurement policies, as well as the blood centre's optimal production policy in the presence of options contracts. Secondly, the blood supply chain coordination conditions are derived, which are not related to the unit wholesale price, but depend on the blood production random yield rate of raw blood. Finally, we show that there always exists a Pareto contract as compared to the non-coordinating contracts when the blood supply chain is coordinated.
