Method for detecting host resource satisfiability for hard real-time services

The invention relates to a method for detecting the host resource satisfiability for hard real-time services. The method comprises step one, initializing a system and incorporating the services into a list RS; step two, obtaining a list RS' through sequencing; step three, detecting whether the RS' is empty or not, if the RS' is empty, turning to the step eight, and if the RS' is not empty, turning to the step four; step four, detecting whether the services can be started after a demarcation point L or not; step five, dispatching and distributing the services which cannot be started after the demarcation point L; step six, dispatching and distributing the demarcation point L and the services which must be finished before the demarcation point L; step seven, reinitializing the list RS' and turning to the step three; and step eight, returning detection results according to turning reasons to finish the detection. According to the method, the accuracy of the detection results is high, and improving of the operati
