Abstract
In ranking decision alternatives, Analytic Hierarchy Process is regarded as one of the
most successful techniques to deal with multiple criteria decision making problems.
Recognizing that tender evaluation is a typical multi-criteria decision making problem,
this paper introduces an evaluation approach based on AHP methodology for ranking
various alternative options, each represents a construction project the tender, and then
selecting the best one. The proposed model can guide decision makers in construction
industry identify contractors with the best potential to deliver satisfactory outcomes in a
final process of tender selection in Kurdistan Region of Iraq. Moreover, in order to
reduce the inherent uncertainty within the AHP, which may significantly affect the
decision process, a new methodology is proposed by using simulation. This model is
tested by a hypothetical scenario where six tenders are evaluated and then, the best
candidate is selected. Furthermore, the criteria used for the tender selection in the model
and the significance of each criterion had been arrived at by conducting the first survey
study for public and private organizations in Kurdistan Region of Iraq.
