Abstract: Based on the research background that there is multi-skilled workforce in enterprise skilled personnel, a hierarchical optimization model of two-stage fuzzy project portfolio selection is established. Optimization objective is maximization of the value of projects, which are selected within fuzzy scenario, and decision variable is numbers of multi-skilled workforce that is assigned into difference skilled personnel. A 0-1 integral optimization model is constructed. Because skilled personnel work in different project, their skill increases. A integral optimization model is set up, the objective function is maximization of the sum of skill increment, and decision variable is numbers of different kinds of skilled personnel that are distributed to each of the selected projects. Genetic Algorithm（GA） is adopted to solve the model, and it is effectively. Simulation test shows the hierarchical optimization model of two-stage fuzzy project portfolio selection can maximize enterprise benefits, and maximize skill increment, through assigning skilled personnel reasonably. This thesis provides a valid approach for combining of short-term and long-tem benefits of enterprise.
