Abstract
An improved tabu search algorithm was utilized to solve vehicle routing problem with time windows and built a general mathematical model corresponding to this problem.In the process of solving,initial solutions were selected from many random structured practical solutions,and 2-opt method was adopted to produce neighborhood and structured dynamic structure tabu list so that the size and structure of tabu list could be changed in the searching process,the overall ability in search excellence was improved.Simulation experiments indicate the feasibility,validity and superiority of the algorithm.
