Abstract
Most public construction sectors are experiencing a significant problem in strategically prioritising and selecting projects from their vast portfolios. This is due to many reasons, including stakeholder interests, impacts on the environment, economic constraints, and technical challenges. Our study seeks to understand this context using Multi-Criteria Decision Analysis methods and suggests improvements. The following research questions will be answered by the thesis: What are the different MCDA methods available for road construction projects portfolio selection? What are their underlying pros and cons? Which MCDA method is best suited for portfolio selection?
This was done by conducting a comprehensive literature review combined with interviewing of relevant stakeholders. Upon interviews, one of the common findings in the old selection system is its subjectivity, which, consequently, requires more systematic objectivity. Our research adds to the understanding of MCDA applications in project portfolio selection by indicating the need for a more systematic, transparent, and objective decision-making process. It underlines the need to have the choice of projects aligned with the strategic objectives of the public construction sectors and good practices embraced across the sector. The study offers insights likely to refine strategic prioritisation within the road construction project.
