Adaptive scheduling technique for mission critical systems

摘要

An improved scheduling system which normally schedules the operation of number of functions using a shared resource based on time considerations is modified so as to provide a means to predict when the system has a condition that may cause the system to operate below the level required to operate all the functions. When the warning condition is triggered, the scheduler shifts to value based system where critical systems are given priority based on their criticality to the survival of the system.
