针对传统蚁群算法在构造解的过程中收敛速度慢且容易陷入局部最优问题,提出了一种改进蚁群算法。在蚁群搜索路径过程中,通过建立信息素启发式因子α和期望启发式因子β的互锁关系,动态自适应调整α和β;结合车辆运输调度问题,对距离启发式因子ηij(t)进行重新定义,引入不同客户间的“偏好力”,提高算法的搜索效率及实用性。将改进蚁群算法分别应用到机器人路径规划及车辆调度问题并进行仿真,取得了较好实验效果,验证了该方法的可行性和有效性。
針對傳統蟻群算法在構造解的過程中收斂速度慢且容易陷入跼部最優問題,提齣瞭一種改進蟻群算法。在蟻群搜索路徑過程中,通過建立信息素啟髮式因子α和期望啟髮式因子β的互鎖關繫,動態自適應調整α和β;結閤車輛運輸調度問題,對距離啟髮式因子ηij(t)進行重新定義,引入不同客戶間的“偏好力”,提高算法的搜索效率及實用性。將改進蟻群算法分彆應用到機器人路徑規劃及車輛調度問題併進行倣真,取得瞭較好實驗效果,驗證瞭該方法的可行性和有效性。

Due to slow convergence speed and easy to fall into local optimum in traditional ant colony algo-rithm,the pheromone heuristic factor α and expected heuristic foctor β are modified adaptively.By combin-ing with vehicle routing and scheduling problems,the distance heuristic factor ηij(t) is redefined,and the pref-erence force among different customers is introduced to improve the search efficiency and practicality of the al-gorithm. Finally,the improved algorithm is applied to the path planning for mobile robot and vehicle routing scheduling problems respectively. Through the simulation of different application targets,the feasibility and ef-fectiveness of the algorithm are verified,and a good experiment effect has been achieved.
