Unmanned aerial vehicle path scheme optimal evaluation based-VIKOR

A path scheme preferential evaluation system based on VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is proposed to deal with the path planning scheme selection problem in the process of unmanned aerial vehicle flight, and comprehensive threat models are established for each threat sources. To get the comprehensive threat information from each threat sources quickly, comprehensive threat computation models are constructed. Using the line segmentation and the definition of limit, the range of model parameters are also given. The index weight is determined by the coefficient of variation, and the threat information is fused using the VIKOR algorithm which can maximize the group interest and weaken the individual regret. The path plan optimal evaluation method based on VIKOR and its steps are given. The evaluation method can obtain a priority level compromise optimal path scheme, which makes the evaluation result more easily accepted by the decision maker. The effectiveness of this method is verified by the optimization of the actual path planning. Copyright ©2020 Control and Decision.
