Effectiveness evaluation of early-warning aircraft based on hierarchy TOPSIS

Effectiveness evaluation of EWA is one of foundations that the military conductor carries on battle deployment.After analysing the research of status quo,a hierarchy technique for order preference by similarity to ideal solution(TOPSIS)is put forward to evaluate the effectiveness of EWA.Firstly,the index which affects the effectiveness of EWA is classified and the hierarchy index system is established.Secondly,the multiple attribution decision making mathematics model of the hierarchy TOPSIS is set up and the entropy power process is adopted to solve index power coefficient.Finally,a typical example indicates that the method is effective and feasible.
