A decision support system framework for public project portfolio selection with argumentation theory

Abstract

In this chapter, we propose a framework for a Decision Support System (DSS) to aid in the selection of public project portfolios. Organizations are investing continuously and simultaneously in projects, however, they face the problem of having more projects than resources to implement them. Public projects are designed to favor society. Researches have commonly addressed the public portfolio selection problem with multicriteria algorithms, due to its high dimensionality. These algorithms focus on identifying a set of solutions in the Pareto frontier. However, the selection of the solution depends on the changing criteria of the decision maker (DM). A framework to support the DM is presented; it is designed to help the DM by a dialogue game to select the best portfolio in an interactive way. The framework is based on the argumentation theory and a friendly user interface. The dialogue game allows the DM to ask for justification on the project portfolio selection.
