Representative welding shop scenario
Temsilî vaka çalışması — modellenmiş risk, doğrulanmış müşteri sonucu değildir.
Sorun
A fab shop quotes labor and material but under-loads fit-up, rework, and gas consumables — visible margin erodes after callbacks.
Girdi seti
- Material cost, labor hours, labor rate
- Gas/consumables, fit-up hours, rework risk %
- Target margin
Gizli kayıp
Fit-up, rework buffer, and consumables under-loaded in the headline weld quote.
Rework & fit-up buffer
Hesaplama sonucu
Modeled loaded weld cost exceeds quick quote by an illustrative margin gap — see tool for threshold read.
Base weld cost loaded with hidden multipliers for fit-up, rework buffer, and volatility band; minimum safe price at target margin.
Önerilen aksiyon
Compare quoted price to minimum safe floor before accepting the job.
Tahmini etki: Modeled waste exposure if quoted below P90 cost band — illustrative range only.
Yöntem notu
Deterministic weld bid model with user rework risk — representative framing only.
- Flat labor rate; consumables as entered
- Rework risk percent drives tolerance multiplier
- Representative scenario — modeled exposure, not a verified customer outcome.
