The work aims to select the optimal design solution to solve the problem of subjective and one-sided evaluation of intelligent hydraulic equipment design solutions. According to the questionnaire research and experts' opinions, evaluation indicators of intelligent hydraulic equipment were initially constructed and the evaluation model of intelligent hydraulic equipment design scheme was established. 4 criterion layer indicators and 12 sub-criterion layer indicators were constructed through Analytic Hierarchy Process (AHP). The final weight result and ranking of different indicators were obtained through calculation. Finally, the design solution of 3 types of four-column permanent magnet powder hydraulic equipment was evaluated through TOPSIS. The ranking of proximity degree was obtained through calculation to determine the optimal solution. The combined qualitative and quantitative evaluation method of AHP-TOPSIS is used to evaluate the four-column permanent magnetic powder hydraulic equipment design solutions that best meet the needs of enterprises, and to provide reference for the design practice and evaluation of four-column permanent magnetic powder hydraulic equipment and similar intelligent hydraulic equipment.
