摘要:

针对动态综合测度问题,提出一种具有“三维(X维、Y维、Z维)”决策的综合测度方法。在定义信息度的基础上,提出测度指标在不同时间样本点上的权重系数。同时,在定义X维、Y维、Z维等三维空间的测度矩阵和排序指数基础上,构造了综合测度排序指数。利用各状态的综合测度排序指数,对各状态进行排序和分类研究。应用结果表明,该法的测度结果与其他方法的测度结果一致,能够较好地反映实际情况,而且该法计算科学,过程简单,易于实施。

Abstract:

Aiming at the dynamic measure problems, a new comprehensive measure method based on 3 dimension ( X dimension,  Y dimension and Z dimension) decision making is presented. Based on entropy, the weight of the measured index is decided by the information degree of the value of the measured indexes. Based on measure matrix and arrange exponent in 3 dimension space, a comprehensive measure prior exponent is set up. The application results validates the new method is feasibility in dynamic comprehensive measure. It is consistent with the results of other methods. The measuring results can reflect the actual situation. The dynamic comprehensive measure model is scientific and the process is simple.
