摘　　要：本文基于一个ATO生产商的实践,考虑一个需求不确定并具有子装配件的单周期ATO系统,为了应对较长的采购提前期和有限产能的挑战,生产商可以在得到确定的需求之前提前采购零件,装配子装配件以至于最终产品。由于产品物料清单结构中存在子装配件作为可选的中间件,因此完全使用零件和使用子装配件装配最终产品的不同,造成装配能力在时间上具有可变性。我们对此问题建立了利润最大化模型,分析在上述ATO环境中的最优库存和生产决策。通过一系列最优解的性质,我们得到了该问题的有效解决方法。Motivated by the practice of an ATO manufacturer,a single-period ATO system with subassembly and uncertain future demand is considered.To cope with the challenges of long component procurement lead times and limited assembly capacity,the manufacturer may need to procure components,and assemble some quantities of subassembly or the final product before the actual order quantity is confirmed.Since there is subassembly in the product BOM as an intermediate production,the assembly capacity is variable with respect to assembly with components or subassembly over different time slots.A profit maximization model to analyze the optimal inventory and production decisions under the above ATO environment is presented.Structural properties of optimal solutions is estabilished and efficient solution procedures for the proposed problem is developed.
