Multi-level Fuzzy Evaluation for Safety of Floating Bridge n Complicated Environment

摘要

From the standpoint of system engineering, multilevel fuzzy method was used to evaluate the safety of floating bridge. Considering the battlefield tactics factor and technical factor, the index system was built and 8 modules for comprehensive factor influence assessment and 24 modules for specific factor influence assessment were included. Expert evaluation method was used to determine the weight and membership degree of each factor, and the comprehensive safety of floating bridge was found. In the end, the safety state of this system was analyzed according to safety degree. The case analysis results showed that: the system analysis method was feasible and effective in the application research of the safety of the floating bridge in complicated environment.
