Sažetak
Effective decision-making process is the basis
for successfully solving any engineering problem. Many
decisions taken in the construction projects differ in their
nature due to the complex nature of the construction pro
jects. One of the most crucial decisions that might result in
numerous issues over the course of a construction project
is the selection of the contractor. This study aims to use the
ordinal priority approach (OPA) for the contractor selection
process in the construction industry. The proposed model
involves two computer programs; the first of these will be
used to evaluate the decision-makers/experts in the construction projects, while the second will be used to formulate the OPA mathematical model. The experts’ interview
was used to identify the criteria of evaluation process of the
decision-makers/experts, while Delphi survey with principal component analysis (PCA) was conducted to identify
the required selection criteria of the construction projects
contractors. The results illustrate that there are 20 criteria
for selecting the construction contractor, and 7 criteria for
evaluating the decision-makers/experts in the construction
projects. Finally, the proposed model has been applied in a
real construction project, and showed good results.
