摘　　要：从因素权重的变化率出发对状态变权向量的变权效果进行分析,揭示了状态变权向量的变权规律和变权综合的工作机理;随后,结合因素状态值水平组态的均衡程度,讨论了应用变权综合时确定状态变权向量的一般思想,同时对指数型状态变权向量给出了一个具体的、可操作性很强的确定参数的方法,为解决变权原理中如何选择合适的状态变权向量这一难题找到了一条有效的途径.最后,通过一个实例对该方法的应用进行了分析、验证.Via analyzing the weights transferring effect of state variable weights vector from the viewpoint of weight increase rate, the law of weights transfer between factors and the mechanism of variable weight synthesis are revealed. Furthermore, after considering the balance level of factor state values vector, the general principle of selection an appropriate state variable weights vector in decision making is discussed. Simultaneously, a method to determinate the parameter of a kind of exponential state variable weights vector is given. Finally, an example is given to illustrate this approach.
