An ANP- and AHP-based approach for weighting criteria in public works bidding

Abstract

When the bidding conditions for a new public works contract are officially published, the contracting authority should count with objective criteria and weights to evaluate tenders. The evaluation criteria and weights are obtained from official contract documents. In this paper a new approach for the selection and measurement of the bidding criteria based on Analytic Hierarchy Processes (AHP) and Analytic Network Processes (ANP) is proposed. A hierarchy model and a 21-criterion network model have been developed and applied to two real cases: the first one is devoted to study the public bidding for the construction of an educational centre at the Polytechnic University of Valencia, whereas the second one analyses the public bidding for the remodelling and improvement of one section of a national road.
