Project interdependency modeling and analysis have has been ignored in project portfolio management. There are five types of project portfolio interdependencies: benefit, risk, outcome, schedule and resources. In the case of risks interdependencies a positive or negative correlation of risks occurs provoking risk diversification or amplification effects. In this work project portfolio risk interdependencies are modeled using the computing with word (CWW) paradigm. We propose a new method for modeling project portfolio interdependencies, and specially risks interdependencies, using the 2-tuples linguistic model and fuzzy cognitive maps. This proposal has many advantages for dealing with linguistic information making simpler the elicitation of knowledge from experts. Building a 2-tuple fuzzy cognitive map follows an approach more similar to human reasoning and the human decision making process. An illustrative example showed the applicability of the proposal.

Abstract
Project interdependency modeling and analysis have has been ignored in project portfolio management. There are five types of project portfolio interdependencies: benefit, risk, outcome, schedule and resources. In the case of risks interdependencies a positive or negative correlation of risks occurs provoking risk diversification or amplification effects. In this work project portfolio risk interdependencies are modeled using the computing with word (CWW) paradigm. We propose a new method for modeling project portfolio interdependencies, and specially risks interdependencies, using the 2-tuples linguistic model and fuzzy cognitive maps. This proposal has many advantages for dealing with linguistic information making simpler the elicitation of knowledge from experts. Building a 2-tuple fuzzy cognitive map follows an approach more similar to human reasoning and the human decision making process. An illustrative example showed the applicability of the proposal. The paper ends with recommendation of future works that will concentrate on three objectives.
