| 摘 要： | 为了解决配送问题，对离散粒子群优化算法进行改进，保留惯性权值对速度的影响，把粒子的解储存为数组形式．增加群体相似度和排斥算子来让粒子跳出局部最优；仿真结果与其它算法的结果进行对比，发现改进的粒子群算法能够找到更好的解，并且收敛速度快，能在一定程度上避免早熟现象。

| Abstract: | Discrete PSO algorithm is improved to solve distribution problem, keep the influence from the inertia weight to the speed, use array to store the answer of particle, add swarm similar level and repulsion operator to make the particle out of the local best. The simulation results show the improve of discrete PSO algorithm can find a better answer and the speed of convergence is more quickly, it also can avoid premature of particle swarm optimization. |
