Abstract: According to the features of clothing distribution timeliness, the clothing timelines fuzzy math formula is built.With the formula and clothing Vehicle Routing Problem,the timeliness clothing model is discussed. On the basis of the model,to analysis Ant Colony Algorithm,Modified Ant Colony Algorithm is studied,which is for the timeliness clothing model.The optimal nature of the MACA is that task weights with the clothing timelines have right to update the information function of clothing Vehicle Routing.The results indicate that,comparing to the existing Ant Colony Algorithm,the MACA proposed by the paper can enhance the ability to find the soultion of the clothing VRP with timeliness.The feasibility and rationality of the models and the algorithm are verified by practical examples.
