Our paper mainly discusses the order of Beijing Olympic Games arrange bus to transport Olympian to every gym, in order to spend time as short as possible to finish a circle for next time transporting. First of all, our paper based on Matlab, using Greedy Algorithms figure out this problem and get the problem's Pareto optimal solution. Next, we set up a mixed integer programming model in Lingo as another scheme for the optimal solution. In the end, we compare the two models with algorithms time co...
