PLM, BOM & Digital Thread worked example

Manufacturing BOM Conversion Load at 12% setup, review, and rework allowance: a worked example

What does the result look like when setup, review, and rework allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when manufacturing bom conversion load in plm, bom and digital thread needs a defensible run time before a quote goes out.

The inputs for this scenario

  • BOM line items to convert from EBOM to MBOM: 120 units (unchanged)
  • Line items converted per minute: 12 units / min (unchanged)
  • Setup, review, and rework allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base manufacturing bom conversion load time = manufacturing bom conversion load workload รท manufacturing bom conversion load completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required manufacturing bom conversion load time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base manufacturing bom conversion load time.
  • At this operating point the engine returns 12 % for manufacturing bom conversion load allowance applied.
  • At this operating point the engine returns 12 pieces / min for manufacturing bom conversion load completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, review, and rework allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when setup, review, and rework allowance is genuinely sustained, not just peaked for a shift. It assumes a steady conversion rate; complex multi-level BOMs, alternate parts, and where-used rework can make actual throughput far lumpier than the average implies.

Results at a glance

  • Required manufacturing bom conversion load time: 11.2 hr (headline result)
  • Base manufacturing bom conversion load time: 10 hr
  • Manufacturing bom conversion load allowance applied: 12 %
  • Manufacturing bom conversion load completion rate: 12 pieces / min
