针对制造系统中的任务分配问题,提出了一种基于信息素的协调方法并搭建了原型实验仿真平台。该协调方法源于蚁群的觅食行为活动,蚂蚁在觅食的路径上会留下一种特殊的化学物质(信息素),利用该介质,可以更好地在群体内部实现协调与合作。基于信息素的协调方法可以自动寻找到有效的加工单元来处理所需要加工任务,有效地克服以往存在于基于合同网协调机制中的通信信息量大等不足。实验结果证明了基于信息素的协调机制对任务分配具有极其稳定的优化能力。 Aiming at the problem of task assignment in manufacturing system, a pheromone-based coordination method is proposed and a prototype experiment simulation platform is set up. The coordination method stems from the activity of ant colony’s foraging behavior. Ants will leave a special chemical substance (pheromone) on the path of foraging. With this medium, the coordination and cooperation within the colony can be better realized. The pheromone-based coordination method can automatically find effective processing units to handle the required processing tasks and effectively overcome the large amount of communication information that existed in the contract-based network coordination mechanism in the past. Experimental results show that the pheromone-based coordination mechanism has extremely stable optimization ability for task assignment.
