基于模糊综合评判的设施栽培旋耕机选型研究

Research on selectiong system of totary tiller on facility agriculture

旋耕机选型在农业机械的节本增效以及更新换代中具有十分重要的意义。选型的基本原则是经济合理、技术先进、操作方便和安全可靠,其中设施大棚内作业的旋耕机还需考虑其尺寸大小问题,由于影响旋耕机选型的因素较多,旋耕机的选型大多通过经验评判和定性分析的方法,难以科学合理地作出选择。在此前提下,本文以实验数据为基础,应用模糊综合评判法和德尔菲法,以旋耕机的经济适用性、可靠性、安全性和性能作为主要评价指标对预选旋耕机进行二级评判选择,试图建立旋耕机选型系统,为后期旋耕机选型研究提供了基础性的依据。

Rotary tiller selection has very important significance on low input but output and updating of agricultural machinery. The basic Principle of selection is economically reasonable, safe and reliable, technologically advanced and easy to operate, operating in the facilities greenhouse it also take its size problems into account, because of the restrict of many factors on the selection of rotary tiller, experience judgment and qualitative analysis being as main methods within a long time, it is difficult to make scientific and rational choice. This paper attempt to establish Rotary tillers selection system by two stage evaluation selection for rotary tiller, as the main index of rotary tiller＇ s economic suitability, reliability, security and performance, using fuzzy comprehensive evaluation method and the delphi method base on experimental data, so as to provide the fundamental basis for future research
