Supplier Evaluation Process by Pairwise Comparisons

Abstract EN

We propose to assess suppliers by using consistency-driven pairwise comparisons for tangible and intangible criteria.

The tangible criteria are simpler to compare (e.g., the price of a service is lower than that of another service with identical characteristics).

Intangible criteria are more difficult to assess.

The proposed model combines assessments of both types of criteria.

The main contribution of this paper is the presentation of an extension framework for the selection of suppliers in a procurement process.

The final weights are computed from relative pairwise comparisons.

For the needs of the paper, surveys were conducted among Polish managers dealing with cooperation with suppliers in their enterprises.

The Polish practice and restricted bidding are discussed, too.
