说明：  其基本原理，是通过检测评价对象与最优解、最劣解的距离来进行排序，若评价对象最靠近最优解同时又最远离最劣解，则为最好；否则不为最优。其中最优解的各指标值都达到各评价指标的最优值。最劣解的各指标值都达到各评价指标的最差值。
(Its basic principle is to sort by detecting the distance between the evaluation object and the optimal solution and the worst solution. If the evaluation object is closest to the optimal solution and at the same time furthest away from the worst solution, it is the best; otherwise, it is not the best. Each index value of the optimal solution reaches the optimal value of each evaluation index. Each index value of the worst solution reaches the worst value of each evaluation index.)
