With the rapid developments of wireless communication technologies and mobile smart devices, people can search the goods information and buy them anytime anywhere. The change of shopping behavior leads to a large number of goods need to be transported and grows up the revenue of logistics. It is a challenge to satisfy real logistic constraints, such as the limitation of vehicle capacity and the available time windows of each customer. To solve this topic, there are a lot of methods wrer proposed. The Ant Colony Optimization is a suitable one I think...
