摘　　要：机载公共设备的综合管理是一种必然趋势,多处理机任务分配和调度是机载公共设备综合管理系统中一个关键技术问题。针对混合任务和不确定的负载,设计动态反馈调度算法使之具有检测、分类、自适应、反馈的功能,采用静态分配和动态调度相结合的方法、局部反馈和全局反馈调度相结合的方法,实现多处理机欠载、过载、超过载、优先级倒置、任务接收和任务拒绝情况下的动态调度。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.
