An Analytic Hierarchy Process Approach For Supplier Evaluation and Selection in a Steel Manufacturing Company

Supplier selection is a complex problem involving qualitative and quantitative multicriteria. A trade-off between these tangible and intangible factors is essential in selecting the best supplier. This problem initiated when there are limitations in the capacity in which the managers are compelle...
