This paper proposes an improved scheduling model and algorithm which threads in the fixed-priority policy have faster response time and turnaround time than existing ones in SRT system. Sub run queue is added into the system and is used for the quick execution and aging of threads in the fixed-priority policy. Using simulation two method are compared. The results shows that the new scheduling model gets threads in the fixed-priority policy to run faster than existing ones.
