Representative welding shop scenario
Scénario représentatif — exposition modélisée, pas un résultat client vérifié.
Problème
A fab shop quotes labor and material but under-loads fit-up, rework, and gas consumables — visible margin erodes after callbacks.
Jeu d'entrées
- Material cost, labor hours, labor rate
- Gas/consumables, fit-up hours, rework risk %
- Target margin
Perte cachée
Fit-up, rework buffer, and consumables under-loaded in the headline weld quote.
Rework & fit-up buffer
Résultat du calcul
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.
Action suggérée
Compare quoted price to minimum safe floor before accepting the job.
Impact estimé: Modeled waste exposure if quoted below P90 cost band — illustrative range only.
Note méthodologique
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.
