基于模糊DEA法的农机选型研究

Study on Selection of Agricultural Machinery Based on Fuzzy DEA Method

传统的农业机械选型方法存在着渗入过多主观因素,不够客观或者计算模型复杂、操作较难的问题。模糊DEA(Data Envelopment Analysis)法能够避免主观评判偏差,评价结果客观,且数据处理和计算操作简单。针对传统农业机械选型过程中存在的问题,采用模糊数据包络分析法,以新疆生产建设兵团农四师68团29.4k W拖拉机选型为例,建立选型模型,借助Lingo(Linear Interactive and General Optimizer)软件对该模型进行求解,并将结果与68团现有机型进行分析比较。结果表明:该方法具有可行性和实用性,且具有广泛的推广价值。

Traditional methods of agricultural machinery equipment selection,some of that have too many subjective factors or their calculation model are complex and difficult. Fuzzy DEA method can avoid subjective bias,the results are more objective,the data processing and the computation operation are simple as well. In order to solve the problems in selection of agricultural machinery,this study,taking the selection of 29. 4k W tractor in the 68 regiment of the Xinjiang production and construction Corps four Division as an example,uses fuzzy DEA to establish selection model,and solves the model in virtue of Lingo（ Linear Interactive and General Optimizer） software. Finally,the results are compared with the 68 existing models. Results show that the method is feasibility and practicability,with a wide range of promotional value.
