A Human Perspective of Contractor Prequalification

Prequalification of Construction Contractor using a FAHP

Analytical hierarchy process (AHP) as multiple criteria decision making tools can be used in the problems with spatial nature like selection of construction contractor. In this study the application of AHP and its weakness and strength and ultimately the fuzzy modified analytical hierarchy process (FAHP) is proposed after the concept of fuzziness, uncertainty and vagueness. A triangular fuzzy u...

An AHP model for construction contractor prequalification

Given that contractor plays a critical role in any construction project, contractor selection constitutes key decision for public authorities. Prequalification, i.e. the elimination of incompetent contractors from the bidding process according to a predetermined set of criteria, is a frequently practiced procedure in many countries, including Greece. In order to enhance the performance levels o...

A Fuzzy Neural Network Approach for Contractor Prequalification

Nonlinearity, uncertainty and subjectivity are the three predominant characteristics of contractors prequalification which cause the process more of an art than a scientific evaluation. A fuzzy neural network (FNN) model, amalgamating both the fuzzy set and neural network theories, has been developed aiming to improve the objectiveness of contractor prequalification. Through the FNN theory, the...

Cp - Dss : Decision Support System for Contractor Prequalification

A prototype decision support/expert system for contractor prequalification, CP-DSS, is described. The system firstly evaluates contractors' capabilities according to project specific criteria. It then identifies any risks that may be caused by contractors. Finally, contractors are appraised according to their likely performance, management capability, reputation, resources, progress, competitiv...
