摘要
为了满足产品模拟成本自顶向下逐层分解计算的管理需求,提出了一种新的数据结构——模拟成本BOM权树。借助单层BOM和多层BOM数据表设计优点,设计了在关系数据库保存模拟成本BOM权树的混合权重BOM数据表结构,该结构有利于提高模拟成本系统运行的效率、方便维护和节省存储空间。最后给出了基于该结构的产品模拟成本计算流程。
In order to meet a decomposing computation from up to down decomposition, BOM weighted tree for simulated cost is defined. Moreover, a relation data table structure of mixed weight BOM for simulated cost is designed with the help ofmonolayer BOM and multilayer BOM design strategy, which is good for basic information requirements and data maintenance of simulated cost system and in economizing storage space. Finally, the computation program of simulated cost based on the structure is provided.
