摘要

在以往的研究中,对专门用于风险评估的扩展订单量表(EOS)进行了分析。用面向梯形模糊数(TrOFNs)评价的数值顺序尺度(NOS)来表征其特征。然而,研究表明,两阶段定向阶段的EOS过于复杂。因此,本文的主要目的是将完全阶标度(COS)简化为零阶或单阶阶标度和混合方法。为此,提出了一种计算计分函数的方法。结果表明,COS结构的变化会影响评分函数的值。仅仅替换一个语言指标就会得到不同的结果。该研究的另一个发现是该方法的灵活性,允许专家单独选择最合适的COS。研究表明,各种语言标签之间的边界是无法精确界定的。但是,对正式COS结构的了解允许将其转换为不那么复杂的结构。

Modifications of order scales for assessing debtors
In previous research, the Extended Order Scale (EOS) dedicated to risk assessment was analysed. It was characterised by a Numerical Order Scale (NOS) evaluated by trapezoidal oriented fuzzy numbers (TrOFNs). However, the research showed that EOS with two-stage orientation phases, was too complicated. Therefore, the main aim of our paper is to simplify a Complete Order Scale (COS) to a zero- or one-stage order scale and a hybrid approach. For this purpose, a way to calculate the scoring function is presented. The results show that changes in the COS structure influence the values of a scoring function. Replacing just one linguistic indicator gives different results. Another finding of the research is the method’s flexibility that allows an expert to individually choose the most suitable COS. The research proves that the boundary between various linguistic labels cannot be precisely defined. However, knowledge of a formal COS structure allows it to be transformed into a less complex one.
