其他摘要:Organizations often approach portfolio optimization problems. In many practical cases, the decision - maker faces uncertainty relating to future uncertain states of nature that cause variability in project benefits, in resources to b e consumed by the project and resources available to support the portfolio, this often carries uncertainty, due to cognitive limita tion of human beings, a great quantity of deal of the information of interest. We used an interval approach for describing and representing uncertainty associated with problems of real - life decision - making. The aim of this work is to provide an approach of handling the uncertainty found in project portfolio selection using grey numbers, which are a way of interval numbers. A fundamental step of our proposal was to generalize NSGA - II for the treatment of multi - objective grey optimization problems. Our propos al provides a better quality of solution concerning the treatment of uncertaint
