基于模糊综合评判法的设施蔬菜移栽机优化选型

Optimal Selecting of Vegetable Transplanting Machine Based on Fuzzy Comprehensive Evaluation Method

由于设施蔬菜移栽机选型因素较多,仅通过性能指标难以做出科学合理的选择。为此,基于试验数据分析,应用模糊综合评判法和德尔菲法,以移栽机的性能、经济适用性、可靠性和安全性作为主要评价指标对3种预选机型进行了二级评判和选型排序。结果表明,模糊综合评判法可将移栽机的技术、经济、使用条件等要求有机结合,对农民科学合理地购买机具有一定的指导作用。并建立了移栽机选型系统,为农业机械的定量化选型提供依据。

There are many factors in the selection of vegetable transplanting machines,which is difficult to make scientific and reasonable choices only through performance index. Based on experimental data,three kinds of transplanting machines were selected by fuzzy comprehensive evaluation and Delphi method. Evaluation results showed that fuzzy comprehensive evaluation method can organically combine requirements of transplanter with its technology,economy and conditions of use. It could guide peasants how to purchase machines economically and reasonably. Established transplanter selection system for quantitative selection of agricultural machinery could provide fundamental basis for future research.
