The positive impacts of managing projects as a portfolio are quantified by comparing the value of the integrated risk of a project portfolio and the aggregation of single project risks implemented separately. Firstly, the integrated risk is defined by proposing risky events based on set theory. Secondly, as projects interact with each other in a project portfolio, the integrated risk is evaluated...
The risk of a project portfolio is assessed using a new methodology that identifies the risk transfer in projects by using a Bayesian network structure learning algorithm to construct an interdependent network of risks. In particular, to overcome the drawback of a greedy search algorithm having a random starting structure, the mutual information between project risks is measured before executing the...
