摘要

决策过程包括为所分析的问题找到最佳解决方案。在逐个标准分析备选方案时,要面对无数的相互作用,在此基础上分配权重,以区分这些标准对决策者的重要程度。对每条标准的权重进行定义时,会产生三种思路。有客观法、主观法和混合法。本讨论涉及专家定义标准权重的程度。基于这一讨论,我们开发了一种混合方法,将熵法和 CRITIC 法与 PROMETHEE 法结合起来,称为 EC-PROMETHEE。这种方法的创新之处在于,熵法和 CRITIC 法的结合不会产生单一的权重集。实际上,每种方法产生的权重都用来定义每个标准的上限和下限。为每个标准生成的权重范围会被模拟 "n "次,并建立一组权重,应用于排序定义过程。该模型会生成 "n "个排名,并定义一个排名。在本文中,我们逐步演示了使用 Python 开发的工具 EC-PROMETHEE 的应用,并以选择旋翼机应用于武警部队的问题为例进行了说明➢该方法减少了确定标准权重时的自由裁量权;➢创新之处在于使用了标准权重范围;➢在定义最终排名时保持了一致性。

New hybrid EC-PROMETHEE method with multiple iterations of random weight ranges: Step-by-step application in Python

New hybrid EC-PROMETHEE method with multiple iterations of random weight ranges: Step-by-step application in Python

The decision-making process consists of finding the best solution to an analyzed problem. This search is carried out in the face of countless interactions when analyzing an alternative criterion by criterion, under which weights are assigned that distinguish the degree of importance they have for the decision-makers. The definition of weight for each criterion gives rise to three lines of thought on the subject. There are objective, subjective, and hybrid methods. This discussion concerns the degree to which experts define the criteria weights. Based on this discussion, we developed a hybrid method to integrate the Entropy and CRITIC methods with the PROMETHEE method, called EC-PROMETHEE. The innovation of this method is that the combination of the Entropy and CRITIC methods does not result in a single set of weights. In reality, the weights generated by each method are used to define each criterion's upper and lower limits. The range of weights generated for each criterion is emulated "n" times and builds a set of weights that are applied to the ranking definition process. The model generates "n" rankings, defining a single ranking. In this article, we demonstrate a step-by-step application of a tool developed in Python called EC-PROMETHEE and use it as an example of the problem of choosing rotary-wing airplanes for application in the military police service.

  • The method reduces discretion in determining the weights of the criteria;

  • The innovation lies in the use of a range of weights for criteria;

  • Consistency in defining the final ranking.
