一、优劣距离法的原理 优劣距离法提出是基于欧几里德范数测度的优劣解距离法进行分析的。也是在系统工程中有限方案多目标的决策分析常用的一种决策方法。它将原始资料数据归一化后构成规范化决策矩阵,找出有限方案中的最优方案和最劣方案的距离,得出该方案与最优方案的相对接近程度来进行排序。若其中某方案最接近最优方案,同时又最远离最劣方案,则此方案
First, the principle of superiority and inferior distance method The superiority and inferior distance method is proposed based on the Euclidean norm measure of pros and cons distance method. It is also a decision method commonly used in decision-making analysis of multi-objectives of limited solutions in system engineering. It normalizes the original data to form a normalized decision matrix, finds the distance between the optimal solution and the worst-case solution in the limited solution, and draws the relative closeness of the solution to the optimal solution. If one of the solutions is closest to the optimal solution and the farthest from the worst, then the solution
