针对分销网络中各节点独立决策与全局最优并存的现实需求,引入目标级联法用于解决双渠道多级分销网络选址—库存问题。构建了多层级、多节点、多主体的三层级问题求解模型,并采用底层先收敛、局部用遗传算法的协调策略进行求解,实现选址决策、库存决策与线上需求分配决策。以某红酒企业的双渠道分销网络运作模式为案例,对选址—库存模型进行求解与结果分析,并与传统的一体化优化方法的求解效果进行对比,验证了目标级联法在求解选址—库存问题的有效性;通过对需求方差的变化进行敏感性分析表明,为降低需求不确定性对企业物流总成本的影响,应及时优化供应链结构,调整线上需求分配的层级。

In a recent article published in Science,Sharma et *** the essential role of saposins in cross-presentation of tumor membraneassociated antigens by dendritic cells(DC)to CD8^(+)T cells.1 However,antigen cross-presentation,which is fundamental in cancer cell elimination,is hindered in tumor DC by hyperglycosylation of the common saposin precursor prosaposin(pSAP)leading to impaired T cell tumor immunity-yet,the potential of recombinant pSAP to re-establish T cell responses may offer a novel way to counteract immune evasion in a therapeutic approach.
