【摘要】 针对包含一个供应商、一个制造商和一个经销商的三级供应链系统进行研究,并依次将系统中的成员称之为首级、中间级和尾级.在相关文献研究的首级和尾级具有能力约束的供应链系统联合批量模型的基础上,建立了一个中间级具有能力约束的三级供应链系统的联合批量模型,并提出了基于推拉混合规则的新的动态规划算法,可在多项式时间求解供应链系统中各个层级的最优决策批量,并通过相关定理的证明保证了算法能够求得全局最优解.最后通过算例分析对上述方法进行了阐述.更多还原

【Abstract】 A three-level supply chain composed of a supplier,a manufacturer and a distributor was considered,and the three members of the system are respectively called as first echelon,middle echelon and last echelon. Based on the existing supply chain model where the first and last echelons have capacity constraints,a newintegrated lot-sizing model for the three-level supply chain was presented in which the middle echelon has capacity constraints. A newdynamic planning algorithm based on the mixed pull-push rules was proposed to determine the optimal material ordering batches in polynomial time. Some proven theorems showthat the global optimal solution should be achieved. The proposed algorithm was explained via solving a simple problem.更多还原
