将农机装备项目筛选划分为立项评估、性能评估和预警评估,并分析了三类评估之间的关系,提出了农机装备项目筛选的整体评估模型.首先根据筛选目的、评价准则,完成立项评估;再综合利用熵权法和专家组的意见给出指标权重,进而应用TOPSIS法对农机装备项目性能进行评估;并利用集值统计方法分析了指标体系和评价方法所带来的决策风险;最后综合考虑立项评估、性能评估和预警评估的评价结果,给出了最终的决策结果.该方法的分析结果定量、客观,为制定正确、科学的农机装备项目决策提供了重要参考.
The screening of agricultural equipment items is divided into project assessment, performance assessment and early warning assessment, and the relationship between the three types of assessment is analyzed, and the overall assessment model of agricultural equipment project screening is put forward.Firstly, according to the screening objective and evaluation criteria, And then use the entropy method and expert group’s opinion to give the weight of the index, and then use the TOPSIS method to evaluate the performance of agricultural equipment project; and use the set-value statistics method to analyze the decision-making risk brought by the index system and evaluation method; finally, Considering the evaluation results of project evaluation, performance evaluation and early warning evaluation, the final decision-making results are given.The results of the method are quantitative and objective and provide an important reference for making correct and scientific decision-making of agricultural equipment projects.
