| 摘要: |
| 项目组合选择是战略项目管理决策的重要环节，目前基于决策者偏好的交互项目组合选择的研究仍然在模型和算法上存在不足。首先提出级别优先模型细致划分了项目间的偏好关系，并引入了项目间的协同交互，使模型更加完备。进而结合该模型改进了多目标粒子群算法，加快其收敛速度，并拓展其非劣解的多样性。在考虑决策者偏好和项目间交互约束的条件下，分别对偏好模型和模型求解算法进行了仿真验证。仿真结果表明，采用级别优先模型所得的非劣解更加接近项目组合选择的最优解，改进粒子群算法的搜索速度更快。 |

| Abstract: |
| Project Portfolio Selection is known as the essential element of strategic project management and decision. There are also some disadvantages in model and methods which are based on the project portfolio selection considering interdependencies and preference incorporation of decision maker. The paper proposes an novel outranking model to classify the preference relationship between different projects, and it also bring the synergies and interdependencies into consideration which makes the model more complete. Moreover, it proposes the improved particle swarm optimization algorithm based on the model which speeds up convergence an expand the diversity of non-dominant solutions simultaneously. In the restrained condition of preferences incorporation and interdependencies, the paper comes up with the experiments to verify the model and method respectively. The results indicate that the non-dominant solutions achieved by the outranking model are likely to the optimum of project portfolio selection, and the improved particle swarm optimization search the results faster. |
