摘要：
For the fuzziness and randomness of risk assessment of aerospace embedded Linux, a comprehensive assessment method of aerospace embedded Linux based on cloud model theory is proposed. Cloud model was used to replace the traditional membership function. Seven factors of embedded Linux were selected as the risk assessment set, and the risk level was established. By using test data and expert scoring cameras, the weight coefficient matrix and comprehensive evaluation matrix are constructed by the reverse cloud generator, and the comprehensive evaluation grade was obtained by the forward cloud generator. Taking Linux based on PREEMPT-RT patch as an example, the risk assessment method of space embedded Linux based on cloud model was validated. The results show that the assessment method is effective and feasible. © 2018 Totem Publisher, Inc. All rights reserved.
