Abstract:The task changes of Complex Network can cause the evolvement of the network, one of the key problems is how to balance the task load to improve the network's performance. The load balancing rules to configure, divide, add and abandon the object were proposed based on the static and dynamic data with regional express network used as the research object. And then the action of the rules to the load balancing in the task planning was studied. The experimental results show that the rules proposed can effectively improve the stability of similar network and promote the rational use of the network resources.
