چکیده
In this work, a two-echelon location-routing problem with time windows and transportation resource sharing (2E-LRPTWTRS) is solved by selecting facility locations optimizing vehicle routes. The optimal solutions improve the efficiency of logistics network based on geographical distribution service facilities customers. Furthermore, utilization maximized enabling strategies within among different simultaneously. 2E-LRPTWTRS formulated as biobjective optimization model, obtaining smallest number required delivery vehicles minimum total operating cost are two objective functions. A two-stage hybrid algorithm composed k-means clustering extended multiobjective particle swarm proposed for optimization. self-adaptive mechanism flight parameters introduced adopted during iterative process to balance evolution particles algorithm. Moreover, 20 small-scale instances used an comparison genetic nondominated sorting algorithm-II, demonstrate superiority in networks. model tested employing real-world case Chongqing, China, results verify positive role developed improving efficiency, reducing cost, saving resources operations

متن کاملCompetitive Vehicle Routing Problem with Time Windows and Stochastic Demands
The competitive vehicle routing problem is one of the important issues in transportation area. In this paper a new method for competitive VRP with time windows and stochastic demand is introduced. In the presented method a three time bounds are given and the probability of arrival time between each time bound is assumed to be uniform. The demands of each customer are different in each time wind...
