Research of State Assessment for UAV Based on FAHP

Abstract

In the assessment subsystem of the UAV health system ,the analytic hierarchy process method is used to build up a UAV performance assessment model,and to analyze and determine each factor and subordinate degree affecting UAV system performance or conditions. For the UAV monitoring and inspection data that are quantitative,the data are assessed and scored by the fuzzy AHP method,while for the extent of the data that are non-quantitative,the data will be directly assessed and scored according to the expert system. On the basis of comprehensive analysis and calculation,the scores of safety,durability and serviceability of each section of the UAV can be achieved and the weighted factor method is then used to finalize the grades of the health conditions of the UAV. With all methods mentioned above,the real-time assessment of the health conditions of the UAV is realized and scientific bases of decision-making for maintenance and management of the UAV are thus provided.
