多供应商—单制造商—多经销商的供应链协同度研究

目前,针对供应链协同度的分析主要集中在单制造商与单供应商之间,为将协同度问题更为一般化,现将供应链协同问题扩展到多供应商、单制造商与多经销商情景中。基于供应链整体运营效率的角度,以制造商为主导,从多经销商、单制造商、多供应商与供应链稳定性四个维度构建供应链协同发展指标体系,将评价指标作为供应链子系统的序参量,运用协同学理论的有序度方法分析供应链子系统的协同性及供应链整体系统的协同度。实例分析说明评价指标体系和协同模型的有效性和可行性,针对协同测度结果提出了供应链系统的协同发展对策。

Multiple Multi-Qubit Quantum States Sharing

A multiple multi-qubit quantum states sharing scheme is proposed,in which the dealer can share multiple multi-qubit quantum states among the participants through only one distribution and one recovery.The dealer encodes the secret quantum states into a special entangled state,and then distributes the particles of the entangled state to the participants.The participants perform the single-particle measurements on their particles,and can cooperate to recover the multiple multi-qubit quantum states.Compared to the existing schemes,our scheme is more efficient and more flexible in practice.
