Abstract: In the process of Research & Development (R&D) project portfolio selection, interactions among benefit, technology and resources of projects were analyzed. Fuzzy set theory was applied to define the uncertainty parameters of R&D project. Based on R&D portfolio selection model of independent projects, a general portfolio selection optimization mathematical model was set up covering the three interactions. To solve the fuzzy model, a crisp transformation was implemented based on qualitative possibility theory. Macroscopic and microcosmic strategies of genetic algorithm were presented to solve clear mathematical model. Effectiveness of optimization model and algorithm were proved by a computational example.
