Reliability is one of the evaluation indices of system performance. For improving the reliability of the system, offloading scheme in vehicle edge computing (VEC) has been extensively studied. In order to improve reliability, a priority based reliable offloading scheme is proposed applying a reliability model, which is modeled considering the impact of various evaluation. Specifically, a multi-factor priority evaluation approach is first proposed, taking into account the importance and the urgency of tasks in a comprehensive manner. And then, based on the multi-factor priority evaluation approach, an optimization problem is formulated to maximize the system reliability. Thereafter, a priority based soft actor-critic (P-SAC) algorithm is developed to solve the complex optimization problem effectively. Performance evaluation results validate that the proposed scheme can improve system reliability.
