Abstract:

There is a phenomenon of low test efficiency and long cycle under the existing equipment test model in the army, which is hard to satisfy the increasingly complex test requirements. Considering the time and value attributes and qualitative analysis of the task execution urgency, value density and resource load balancing, the tactics of dynamic priority assignment (DPA) and task preemption (TP), which is used in the beginning of task execution, are studied to achieve the comprehensive optimization of the value gains, task execution success rate and resource load balancing of the automatic test system (ATS), namely the test task preemptive scheduling algorithm based on dynamic priority (TTPSADP).
