Financial markets have been characterized in recent years by their uncertainty and volatility. The price of assets is always changing so that the decisions made by consumers, producers, and governments about different products is not still accurate. In this situation, it is necessary to generate models that allow the incorporation of the knowledge and expectations of the markets and thus include in the results obtained not only the historical information, but also the present and future information. The present article introduces a new extension of the ordered weighted averaging (OWA) operator called the Bonferroni probabilistic ordered weighted average (B-POWA) operator. This operator is designed to unify in a single formulation the interrelation of the values given in a data set by the Bonferroni means and a weighted and probabilistic vector that models the attitudinal character, expectations, and knowledge of the decision-maker of a problem. The paper also studies the main characteristics and some families of the B-POWA operator. An illustrative example is also proposed to analyze the mathematical process of the operator. Finally, an application to corn price estimation designed to calculate the error between the price of an agricultural commodity using the B-POWA operator and a leading global market company is presented. The results show that the proposed operator exhibits a better general performance than the traditional methods.

Bonferroni概率有序加权平均算子在农产品价格分析中的应用

近年来,金融市场的特点是不确定性和波动性。资产价格总是在变化,因此消费者,生产者和政府对不同产品的决策仍然不准确。在这种情况下,必须生成模型,以允许将知识和市场期望结合到一起,从而在获得的结果中不仅包括历史信息,而且还包括现在和将来的信息。本文介绍了有序加权平均(OWA)运算符的新扩展,称为Bonferroni概率有序加权平均(B-POWA)运算符。该运算符旨在通过Bonferroni均值和加权概率矢量对数据集中给出的值的相互关联进行统一表示,该加权概率矢量对问题的特征,期望和决策者的知识进行建模。本文还研究了B-POWA算子的主要特征和一些家族。还提出了一个说明性示例来分析操作员的数学过程。最后,介绍了一种玉米价格估算的应用程序,该应用程序旨在使用B-POWA运营商和一家领先的全球市场公司来计算农产品价格之间的误差。结果表明,所提出的算子具有比传统方法更好的综合性能。和问题决策者的知识。本文还研究了B-POWA算子的主要特征和一些家族。还提出了一个说明性示例来分析操作员的数学过程。最后,介绍了一种玉米价格估算的应用程序,该应用程序旨在使用B-POWA运营商和一家领先的全球市场公司来计算农产品价格之间的误差。结果表明,所提出的算子具有比传统方法更好的综合性能。对问题决策者的了解。本文还研究了B-POWA算子的主要特征和一些家族。还提出了一个说明性示例来分析操作员的数学过程。最后,介绍了一种玉米价格估算应用程序,该应用程序旨在使用B-POWA运营商和一家领先的全球市场公司来计算农产品价格之间的误差。结果表明,所提出的算子具有比传统方法更好的综合性能。提出了一种玉米价格估算应用程序,该应用程序旨在使用B-POWA运营商和一家领先的全球市场公司来计算农产品价格之间的误差。结果表明,所提出的算子具有比传统方法更好的综合性能。提出了一种玉米价格估算应用程序,该应用程序旨在使用B-POWA运营商和一家领先的全球市场公司来计算农产品价格之间的误差。结果表明,所提出的算子具有比传统方法更好的综合性能。
