摘　　要：针对大型工程项目组合管理问题,在分析工程项目组合中项目间收益、资源、工期和结果相关性的基础上,建立考虑相关性的工程项目组合选择数学模型。将合作协同进化算法与遗传算法相结合,应用于工程项目组合选择模型问题的求解,根据工程项目实施阶段划分不同的子种群,各子种群之间通过合作协同进化算法进行协调。最后,通过实例计算验证了算法的有效性和实用性。Aiming at large - scale project portfolio management, a general project portfolio selection mathematical model was set up based on analyzing the correction among benefit, resources, time and results of projects. The cooperative co - evolutionary algorithm combined with genetic algorithm was applied to solve the project portfolio selection model. According to the project implementation phases, the algorithm decomposed those into different sub - populations, and sub - population coevolved with other sub - populations through cooperative coevolutionary algorithm. Finally, effectiveness and practicability of algorithm were proved by a case study.
