Learning objectives
- Explain the purpose of analytical hierarchy process overview in a garment-factory improvement project.
- Apply the described method to a representative shop-floor situation.
- Recognize the common mistakes and how to avoid them.
Concept
AHP structures a complex choice through pairwise comparisons of criteria and alternatives, exposing inconsistency.
Goal sits above criteria, subcriteria, and alternatives; pairwise judgments produce normalized weights.
High inconsistency signals judgments need review, not that AHP failed.
Garment-factory example
Select an inspection technology using detection performance, false alarms, speed, integration, cost, skill, and data governance.
Method
- Build hierarchy.
- Compare pairs on a consistent 1–9 scale.
- Compute normalized priorities in a free spreadsheet.
- Review consistency ratio.
- Test sensitivity to weight changes.
Common mistakes
- Using too many near-duplicate criteria that double-count.
- Presenting subjective weights as objective truth.
