基于AHP-TOPSIS方法的智能液压设备设计评价研究

Evaluation of Intelligent Hydraulic Equipment Design Based on AHP-TOPSIS Method

目的为解决智能液压设备设计方案评价主观片面的问题,优选最佳设计方案。方法根据问卷调研和专家意见初步构建智能液压设备评价指标,建立智能液压设备设计方案评价模型。采用AHP层次分析法从外部形象、生产成本、人机工程、安全可靠4个方面建立4个准则层指标,12个子准则层指标,并通过计算得到各级指标的最终权重结果及排序;再利用TOPSIS逼近理想解排序法对3款四柱永磁粉末液压设备的设计方案进行评价,计算得到贴近度优劣排序,从而确定最优选方案。结论通过AHP-TOPSIS相结合的定性定量评价方法,评估出最符合企业需求的四柱永磁粉末液压设备设计方案,为四柱永磁粉末液压设备及同类智能液压设备的设计实践和评价提供参考。

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.
