Design of Distributed CPS System Task Scheduling Based on Ant Colony Algorithm

For the complexity of the resources and tasks in CPS,meanwhile,in order to ensure the rapidity,accuracy and validity of resource management and task scheduling in CPS,a distributed architecture model of CPS is built,and resource allocation strategy based on ant colony algorithm is designed and implemented.In the algorithm,the update rules of local and global pheromone are designed,combining with the resource management,task scheduling and execution,and considering both of network load balancing and service quality.Using Matlab to do the simulating experiment about the design of distributed CPS's task scheduling based on ant colony algorithm,the results show that the strategy shortens the total completion time of the overall task scheduling,and with the increasing in the number of tasks,the completion time is shortened better significandy.
