Dear, this is the LearingYard Academy!

Today, the editor brings the “Knowledge of multi-attribute decision-making”.

Welcome to visit!

本期小编带大家继续学习上期VIKOR方法的计算步骤：

（2）计算个体遗憾值

In this issue, the editor will continue to learn the calculation steps of the VIKOR method from the previous issue:

(2) Calculate individual regret values

表达公式：

Expression formula:

其中，Ｗｊ表示指标的最终权重，精确数的距离可直接求差的绝对值。

Among them, Wj represents the final weight of the indicator, and the distance of the exact number can be directly calculated as the absolute value of the difference.

（3）计算折中评价值

(3) Calculate compromise evaluation value

含义：根据群体效用值与个体遗憾值的结果，在此基础上计算决策指标Q的值，指标值Q越小方案越优，计算公式如下：

Meaning: Based on the results of group utility value and individual regret value, calculate the value of decision indicator Q on this basis. The smaller the indicator value Q, the better the solution. The calculation formula is as follows:

v是决策机制系数，如果v>0.5，则表示根据最大化群体效应决策机制决策；如果v<0.5，则表示根据最小化个体遗憾值的决策机制决策；如果v=0.5，则表示根据协商达成最大群体效应和最小个体遗憾值同等重要的决策机制进行决策。最终，可以得到各方案的Q值，而Q值越小越好。将进行升序排列得到各方案的排序结果R。

V is the coefficient of the decision-making mechanism. If v>0.5, it indicates that the decision-making mechanism is based on maximizing group effects; If v<0.5, it means making decisions based on the decision mechanism that minimizes individual regret values; If v=0.5, it means that decision-making is based on a decision-making mechanism that achieves the maximum group effect and the minimum individual regret value through negotiation. Finally, the Q values for each scheme can be obtained, and the smaller the Q value, the better. The sorting result R of each scheme will be obtained by ascending sorting.

（4）确定备选方案排序

(4) Determine the ranking of alternative solutions
