Evaluation of the Unmanned Aerial Vehicle (UAV) Recovery System Based on the Analytic Hierarchy Process and Grey Relational Analysis

This paper mainly expounds the commonly used UAV recovery methods nowadays and explains the necessity of effective evaluation of the UAV recovery system according to the previous studies; fully considers the influence factors and construct the evaluation system of the UAV recovery system with six evaluation indexes of safety, cost, personnel requirement, landing environment, time as well as UAV's own scale; and determines the influence weight of the UAV recovery system using the analytic hierarchy process. By combining the qualitative and quantitative analysis, the effective evaluation is conducted on the UAV recovery system with the grey relational degree of the recycle system under different indexes calculated with the grey relational analysis. Due to the subjective influence of experts in scoring, the rationality of the evaluation system and the validity of the evaluation results can be verified through controlling the variables, adjusting the weights of different indexes, and painting the line chart, in which the evaluation results change with the indexes, and evaluating all recovery systems at different indexes.
