Task Scheduling Algorithm in Ship Edge Computing Based on Improved NSGA-Ⅲ
In view of the problem that the existing ship centralized control system can not efficiently handle the rapid growth of elec-tronic equipment and intelligent tasks,the edge computing architecture and task scheduling based on multi-objective optimization were studied.A distributed control architecture of intelligent ship based on edge computing was proposed.Aiming at the scheduling optimi-zation problem caused by many tasks and large amount of computation in the edge computing layer in the architecture,the comprehen-sive performance of the algorithm in computing task scheduling problem was improved and designed based on non-dominated sorting ge-netic algorithm Ⅲ(NSGA-Ⅲ)by improving and designing population coding,initialization population strategy,discrete adaptive cross-over strategy and discrete adaptive mutation strategy.The simulation experiments show that compared with other algorithms,the average performance of the solution set of the NSGA-Ⅲ-ADO algorithm designed is improved by at least 6.8%,5.9%and 0.8%in total com-puting delay,total computing energy consumption and load balancing,and its convergence speed is faster,which can better solve the problem of computing task scheduling.
