Research of Aerial Hydrazine Fuel Guarantee Safety Assessment Based on Vague-SPA and Fuzzy Proximal Grade

摘要

Aiming at the problem of aerial hydrazine fuel guarantee safety assessment, an assessment model based on Vague-SPA and fuzzy close degree was proposed in accordance to the fuzzy matter-element. Firstly, based on the definition and actual situation, an assessment index system and fuzzy matter-element model of aerial hydrazine fuel guarantee were built. Furthermore, the weight was optimized by applying fuzzy close degree of the decision model. The authors built an assessment model with Vague-SPA clustering combined by using fuzzy mathematics and SPA analysis to reduce the influence of subjectivity during the evaluating process. Finally, objective and reasonable results were obtained through a practical example, and it proved the effectiveness of the method and provided a new way for the safe assessment in aerial hydrazine fuel guarantee.
