Study of Physical Distribution Routing Optimization Problem Based on Hybrid PSO Algorithm

To overcome the disadvantages of premature convergent of the PSO, a hybrid PSO algorithm was put forward to solve the physical distribution routing problem. The hybrid PSO algorithm is composed of Powell algorithm and SA algorithm to balance the exploitation and global search abilities. The computational results showed that the hybrid PSO algorithm for solving the physical distribution routing problem can improve the local and global search abilities of PSO algorithm, so the high quality solutions to the physical distribution routing problem can be obtained.
