【摘要】 针对工程项目PERT网络计划工期-费用优化问题,尝试引入粒子群算法。在保证不陷入局部最优的前提下,为提高收敛速度,用线性规划方法建立数学模型,并采用了改进的PSO算法。实际算例的仿真结果表明,该方法具有收敛速度快、运算简单、易于实现等优点。更多还原

【Abstract】 For solving time-cost optimization problems of PERT(Program Evaluation and Review Technique) network plans,the model was represented with linear programming,and a particle swarm optimization algorithm was used to solve this problem.The effectiveness of particle swarm optimization algorithm is proved by an example of the actual application,and the simulation results indicate that the method can be reliably applied to engineering project.更多还原
