【摘要】 在基金项目管理中,同行评议是项目评审的主要方法,而专家分配又是同行评议中首要的、基础的工作,因此对专家分配问题的研究具有很现实的意义。本文建立了专家分配问题数学模型,提出了遗传算法的求解方法,并针对遗传算法局部搜索能力差和运行中后期出现大量冗余迭代的缺点,进一步提出利用蚂蚁算法的正反馈机制指导变异操作的新算法。实验证明,新算法具有更强的收敛能力。更多还原

【Abstract】 Peer review is the main method in project review of project management. Expert assignment is chief and basic work of peer review. So it is significant to study expert assignment problem. In this paper, the mathematical model of expert assignment problem is established, and the solution method of genetic algorithm is proposed. In view of the disadvantages that the partial search ability of genetic algorithm is worst and in later period massive redundancy iteration appears, this paper proposes the new algorithm that uses positive feedback to instruct the mutation. The simulation results show that the new algorithm has strongly convergence ability.更多还原
