简述了ＢＯＭ 的结构特点及其在ＭＲＰ Ⅱ中的重要作用，并以汽车制造业为例，通过分析总成装置间的相互关系，结合零部件在生产制造中的装配顺序，建立了ＢＯＭ 结构，并就其中出现的多对多关系，提出了利用邻接表建立其联系的方法以及如何构造相关数据表单和表单结构，在此基础上讨论了零部件分解和查询的实现方法，该方法适用于一般网状数据关系的ＢＯＭ 结构的建立，具有一定的通用性。
The structural characteristics of BOM and its important role in MRP Ⅱ are briefly described. Taking the automobile manufacturing industry as an example, the structure of BOM is established by analyzing the interrelationship between assembly devices and the assembly sequence of components in manufacturing. , And put forward the method of how to use the adjacency list to establish its contact and how to construct the related data form and the form structure on the many-to-many relationship among them. On the basis of this, it discusses the method of component decomposition and query, which is suitable for The establishment of the BOM structure of the general mesh data relationship has a certain versatility.
