摘要
企业的信息共享可以给供应链带来了更好的效益,但是企业都有各自的私有信息,例如各自的成本信息、质量信息等,因此企业很少能够做到完全信息共享。那么企业在不愿意泄漏各自的私有信息的情况,怎样在合作过程中以整体供应链最优而进行联合决策?本文建立了一个供应商和一个零售商联合进行各自最佳订货决策的模型,并以同态加密的性质来解决成本信息私有时的联合订货决策问题。结果表明基于同态加密性质设计的安全计算协议能在不透漏私有信息的情况下达到完全信息共享时的决策结果。
Information sharing can bring about better benefits to the supply chain. But enterprises in the supply chain have their own private information such as the cost information, quality information. So enterprises can seldom be fully sharing information. How to make joint decision considering the whole supply chain's optimization with private information protection? A model which a supplier and a retailer make the best ordering decision jointly is built in the paper, and homomorphic encryption is applied to solve the cooperative ordering decision with private information protection. The results show that enterprises with private information protection can get the results of complete information sharing by the secure computation protocol based on homomorphic encryption.
