针对动态车辆路径问题DVRP（Dynamic Vehicle Routing Problem）的优化问题，提出一种改进算法。该算法在分析路径寻优问题的局部特性的基础上，利用变邻域搜索算法VNS（Variable Neighbourhood Search）对路径空间进行“局部探索”，结合变异机制对路径空间进行“全局开采”，最后根据近邻优先原则将动态路径片段安插到适宜的路径中。实验结果验证了算法的有效性。
針對動態車輛路徑問題DVRP（Dynamic Vehicle Routing Problem）的優化問題，提齣一種改進算法。該算法在分析路徑尋優問題的跼部特性的基礎上，利用變鄰域搜索算法VNS（Variable Neighbourhood Search）對路徑空間進行“跼部探索”，結閤變異機製對路徑空間進行“全跼開採”，最後根據近鄰優先原則將動態路徑片段安插到適宜的路徑中。實驗結果驗證瞭算法的有效性。

Due to the optimization problem of dynamic vehicle routing problem, an improved algorithm for DVRP (Dynamic Vehicle Routing Problem)is proposed. Based on analyzing local features of routing optimization problem, the method uses variable neighbourhood search heuristics to explore, and combines mutation mechanism to exploit. The dynamic routing blocks are inserted into vehicles according to neighbor priority principle. Experimental results show that the improved algorithm is effective.
