Safety Assessment of Solid Rocket Motor Waterjet Clearing System Based on Grey Analytic Hierarchy Process

Abstract:

Basing on the complexity and uncertainty of many risk factors which were presented in the solid rocket motor waterjet clearing system, according to operating procedures of the waterjet clearing system, the analytic hierarchy process was adopted to establish its safety evaluation index system, and then the gray comprehensive evaluation was used to evaluate the solid rocket motor waterjet clearing system security. The evaluation results indicate that the solid rocket motor waterjet clearing system's comprehensive evaluation value is 3.1126 and at a higher risk situation, thus there is need to strengthen the prevention and control of the risk factors in it; the comprehensive evaluation value of the waterjet clearing platform is 3.2417, which is higher than the overall comprehensive evaluation value, therefore it should be paid attention to in risk prevention and control; the evaluation result is in good agreement with the actual situation.
