研究了具有多个产品的双重采购问题，其中每个产品可以从两个有能力的供应商处采购，一个供应商的生产成本低但可靠性高，而另一个供应商的生产成本高但可靠性高。即使有一次中断，不可靠的供应商也无法交付任何产品。零售商的目标是确定在供应商能力约束下，两个供应商的所有产品的订货量是多少，才能使预期利润最大化。我们使用一个扩展的报贩模型来描述这个问题。为了寻求问题的最优解，提出了一种两层两段搜索法。数值结果被用来评估所提出方法的有效性和双重采购的价值。
This study considers a dual sourcing problem with multiple products in which each product can be procured from two capacitated suppliers, one with low production costs but high unreliability, and the other with high production costs but high reliability. The unreliable supplier cannot deliver any products if there is even one disruption. The objective of the retailer is to determine what order quantities for all of the products from the two suppliers, subject to the supplier capacity constraints, will maximize the expected profit. We use an extended newsvendor model to characterize the problem. A two-tier bi-section search method is developed for seeking the optimal solution to the problem. Numerical results are used to assess the effectiveness of the proposed method and the value of dual sourcing.
