Abstract:
The model of minimum freight cost with time windows has been built for the post VRP with time windows. It has been computed and comparatively analyzed by use of genetic algorithm on the real arrangements of eleven post paths among the Sicuan Province Post, which considered the restrict conditions such as vehicle loading capacity, time windows, and roundtrip collection. The optimization results show that not only the total cost and the vehicle quantity are reduced, but also the real post transport mileages are shortened.
Key words: vehicle routing problems(VRP); genetic algorithms; post; time windows
