基于模糊集的黑龙江水田耕整地机组最优评价

Optimal Evaluation of Paddy Field Tillage Unit in Heilongjiang Province Based on Fuzzy Sets

水田耕整地质量和经济效益是农机经营者所关心的重要问题之一,耕整地作业机组的合理选择是保证耕整地质量和经济效益的关键。为此,通过调查确定黑龙江省水田耕整地机组的类型,选用水田耕整地的技术、经济指标作为水田耕整地机组优劣的评价指标集,分析了技术指标对机组耕整地质量和经济指标对机组经济效益的影响,运用统计方法确定出各指标在整体评价中的相对重要程度,并对技术、经济指标建立了模糊隶属函数。同时,建立了技术经济指标数据的模糊综合评判模型,根据综合评判结果,更加客观地确定出最优水田耕整地机组,为相应地区选择合适的水田耕整地机组提供有益参考。

The quality and economic efficiency of paddy field tillage is one of the important issues of agricultural operators to be concerned,a reasonable choice of tillage operating units is the key factor to guarantee the quality and economic efficiency.In this paper,the type of the paddy field tillage unit in Heilongjiang province was determined by the investigation,the technological and economic indexes of the paddy field tillage was selected to evaluate the merits of the units,the effect of technical indexes on the tillage quality and economic indexes on the economic efficiency was analysed.The statistical methods was used to determine the relative importance of each index in the overall evaluation,and the fuzzy membership function of technical and economic indexes was established,at the same time,the fuzzy comprehensive evaluation model of the technical and economic indexes was established,it is more objectively to give the optimal paddy field tillage unit based on the comprehensive evaluation results.It provide useful reference for the corresponding region to choose the appropriate paddy field tillage unit.
