Aiming at the radar equipment transportation problem with hard time windows in wartime, an improved ant colony algorithm is presented. The improved algorithm adopted Max-Min information element restriction, and adopted rewards and punishment genes to update information element, and adopted local searching strategy 2-opt and or-opt. Given the radar equipment customer number and demand quantity and all the condition, the algorithm can obtain the preferable global solving result. The improved algorithm has faster convergence rate and has higher accuracy, and also has instructional meaning to others transportation problem.
