摘　　要：为研究系统变化趋势和影响因素的作用,基于联系数提出了系统状态趋势与因素诱导趋势分析方法。论述了系统状态趋势和因素诱导趋势的变化特征,计算了各因素区分权重,构造了两种趋势的分析方法。研究表明:基于三支决策的联系数可描述两种趋势;利用模糊隶属函数能表征有利趋势、不确定和不利趋势的隶属程度;减法集对势结果可判断趋势的发展方向。系统状态趋势以系统实例的对象为依据,综合所有因素影响确定系统状态向目标发展的趋势;因素诱导趋势以所有因素对系统的影响为依据,综合所有对象状态确定各因素对系统状态向目标发展的趋势。In order to study the system change trend and the role of influencing factors,an analysis method of system state trend and factor-induced trend is proposed based on the connection number.The change characteristics of the system state trend and factor-induced trend are discussed,the distinguishing weights of every factor are calculated,and the analysis methods of the two trends are constructed.The research shows that the connection number based on three branch decisions can describe the two trends.Fuzzy membership function can be used to characterize the degree of membership of the favorable,uncertain and unfavorable trends.The result of subtraction based set pair situation can judge the development direction of the trend.The system state trend is based on the object of the system instance,and all factors are integrated to determine the trend of the system state toward the target.Factor-induced trend is based on the influence of all factors on the system,and all object states are integrated to determine the development trend of every factor on the system state towards the target.
