of trucks is one of the key factors that incur high costs of mail transportation in China's postal network. How to reduce unnecessary deadhead kilometers of trucks is worthy of being researched. In this paper, we take heterogeneous trucks and facility capacity into consideration of optimizing the postal express line network using Rendezvous driving pattern of trucks. A mixed integer non-linear programming...
A path planning method based on hierarchical hybrid algorithm was proposed, which is aimed at the path planning features in urban road traffic. The method by analyzing and transforming the traffic restriction combines the ant colony algorithm and genetic algorithm. The ant colony algorithm employed at the bottom calculates simultaneously in a few of subnets for the local optimization, and the genetic...
