【摘要】 本文分析了影响手扶拖拉机余值和技术状态等级的主要因素,在此基础上,应用模糊数学中的综合评判方法,建立了手扶拖拉机余值评估和技术状态等级评定的数学模型,提出分别用M(·,V)模型和M(·,(?))模型来确定手扶拖拉机余值和评定其技术状态等级。经过实例验证,取得了比较满意的效果。最后,根据所建立的模型,编制了手扶拖拉机余值评估和技术状态等级评定的BASIC程序。更多还原

【Abstract】 This paper analyzed the main factors of influencing the tractor remaining value and technology state.On the basis of these arguments,the model of multifactorial evaluations was used to formulate the mathematics model of determinating the tractor remaining value and technology state class.In this paper,a M(.,v)model and a M model were separately introduced to determinate remaining value and technology state class of walking tractor,a practice example was given and satisfactory result had been obtained.Finally a BASIC programme of the model was compiled for practice application conveniently.更多还原
