The Best Worst Method (BWM) represents a powerful tool for multi-criteria decision-making and defining criteria weight coefficients. However, while solving real-world problems, there are specific multi-criteria problems where several criteria exert the same influence on decision-making. In such situations, the traditional postulates of the BWM imply the defining of one best criterion and one worst criterion from within a set of observed criteria. In this paper, an improvement of the traditional BWM that eliminates this problem is presented. The improved BWM (BWM-I) offers the possibility for decision-makers to express their preferences even in cases where there is more than one best and worst criterion. The development enables the following: (1) the BWM-I enables us to express experts’ preferences irrespective of the number of the best/worst criteria in a set of evaluation criteria; (2) the application of the BWM-I reduces the possibility of making a mistake while comparing pairs of criteria, which increases the reliability of the results; and (3) the BWM-I is characterized by its flexibility, which is expressed through the possibility of the realistic processing of experts’ preferences irrespective of the number of the criteria that have the same significance and the possibility of the transformation of the BWM-I into the traditional BWM (should there be a unique best/worst criterion). To present the applicability of the BWM-I, it was applied to defining the weight coefficients of the criteria in the field of renewable energy and their ranking.

改进的最佳最差方法(BWM)在现实世界中的应用

最佳最差方法(BWM)代表了用于多标准决策和定义标准权重系数的强大工具。但是,在解决现实世界中的问题时,存在特定的多准则问题,其中多个准则对决策的影响相同。在这种情况下,BWM的传统假设意味着从一组观察到的标准中定义一个最佳标准和一个最差标准。在本文中,提出了消除这种问题的传统BWM的改进。改进的BWM(BWM-I)为决策者提供了表达其偏好的可能性,即使在存在多个最佳和最差标准的情况下也是如此。该开发实现了以下功能:(1)BWM-I使我们能够表达专家的偏爱,而与一组评估标准中最佳/最坏标准的数量无关;(2)BWM-I的使用减少了在比较标准对时出错的可能性,从而提高了结果的可靠性;(3)BWM-I的特点是灵活性,它可以通过现实地处理专家的偏爱的可能性来表达,而不论具有相同重要性的标准数量和BWM-I的转变可能性如何。我加入了传统的BWM(应该有一个唯一的最佳/最差标准)。为了展示BWM-I的适用性,它被用于定义可再生能源领域中标准的权重系数及其排名。(2)BWM-I的使用减少了在比较标准对时出错的可能性,从而提高了结果的可靠性;(3)BWM-I的特点是灵活性,它可以通过现实地处理专家的偏爱的可能性来表达,而不论具有相同重要性的标准数量和BWM-I的转变可能性如何。我加入了传统的BWM(应该有一个唯一的最佳/最差标准)。为了展示BWM-I的适用性,它被用于定义可再生能源领域中标准的权重系数及其排名。(2)BWM-I的使用减少了在比较标准对时出错的可能性,从而提高了结果的可靠性;(3)BWM-I的特点是灵活性,它可以通过现实地处理专家的偏爱的可能性来表达,而不论具有相同重要性的标准数量和BWM-I的转变可能性如何。我加入了传统的BWM(应该有一个唯一的最佳/最差标准)。为了展示BWM-I的适用性,它被用于定义可再生能源领域中标准的权重系数及其排名。(3)BWM-I的特点是灵活性,它可以通过现实地处理专家的偏爱的可能性来表达,而不论具有相同重要性的标准数量和BWM-I的转变可能性如何。我加入了传统的BWM(应该有一个唯一的最佳/最差标准)。为了展示BWM-I的适用性,它被用于定义可再生能源领域中标准的权重系数及其排名。(3)BWM-I的特点是灵活性,它可以通过现实地处理专家的偏爱的可能性来表达,而不论具有相同重要性的标准数量和BWM-I的转变可能性如何。我加入了传统的BWM(应该有一个唯一的最佳/最差标准)。为了展示BWM-I的适用性,它被用于定义可再生能源领域中标准的权重系数及其排名。
