Dynamic feedback scheduling in aircraft utility management system

An inevitable developing trend is to provide an integrated management system for the scattered aircraft utility systems. Multiprocessor task allocation and scheduling is a key technology of the aircraft Utility Management System (UMS). Dynamic feedback scheduling is designed for hybrid tasks and uncertain load to be provided with the function of detection, classification, adaptation, and feedback. The combination scheduling of static allocation and dynamic scheduling, and the united scheduling of global feedback and local feedback were used to carry out dynamic scheduling under the condition of underload, overload, hyper-overload, priority inversion, task acceptance and task rejection.
