Improved ant colony algorithm and its application in routing selection of coal transportation

Based on the characteristics of coal highway transportation,basic ant colony algorithm in terms of selection strategy and volatile speed of pheromones are briefly improved so as to overcome the shortcoming of instability of optimal solution and easy lapsing into local optimal solution.According to the model,feasible solution is constructed,which includes three model loop branches,in order to resolve the difficult of using ant algorithm in finding a feasible solution.Finally,the experimental analysis shows that it is feasible to solve the difficulty in model application with the improved ant colony algorithm.
