With the development of information technology, modern logistics as "the second source of profit" is being increasingly widespread attention, and facing an unprecedented development opportunity. In modern logistics, distribution is an important link with consumers directly connected to, the embodiment of the enterprise's core competitiveness. The logistics and route optimization, optimization of distribution systems is an important part. Through the optimization of distribution routes, can improve company efficiency and reduce distribution costs, logistics and scientific implementation. In the logistics business, delivery vehicle routing problem involves a broader, more factors need to be considered for enterprises to improve service quality, lower logistics costs and increase economic efficiency was also visible.
Logistics is a complicated system, many of which established optimization models and algorithms are complex and have the NP hard nature. Therefore, this scrap metal park in Taizhou logistics system for the application background of the park to optimize delivery routes, solve the vehicle routing problem.
