在本文中，我们分析了TOPSIS方法在结构不良的谈判中支持谈判报价评分系统的适用性。在讨论结构不良的谈判问题时，我们考虑了两个主要问题：不精确定义的谈判空间，以及谈判者偏好的模糊性，无法用清晰的价值观来定义。首先，我们介绍了传统的模糊TOPSIS模型，该模型展示了规范化数据和测量距离的替代方法，这可以避免排名反转的问题。然后，我们使用一个模型将结构不良的谈判形式化，该模型允许仅通过期望和保留级别以简化的方式定义谈判问题。这样的定义需要改变传统的模糊TOPSIS算法，开发一种机制，对谈判者独立和主观定义的谈判空间之外的报价进行评分。我们提出了三种不同的方法来处理这个问题，使计分制度在整个谈判过程中保持稳定和不变。
In this paper we analyze the applicability of the TOPSIS method to support the process of building the scoring system for negotiation offers in ill-structured negotiations. When discussing the ill-structured negotiation problem we consider two major issues: the imprecisely defined negotiation space, and the vagueness of the negotiator's preferences that cannot be defined by means of crisp values. First we introduce the traditional fuzzy TOPSIS model showing the alternative ways of normalizing the data and measuring the distances, which allows to avoid the problem of ranking reversals. Then we formalize ill-structured negotiations using a model which allows the negotiation problem to be defined in a simplified way by means of the aspiration and reservation levels only. Such a definition requires changes in the traditional fuzzy TOPSIS algorithm the development of a mechanism for scoring the offers that fall outside of the negotiation space defined independently and subjectively by the negotiator. We propose three different approaches to handle this problem, that keep the scoring system stable and unchanged throughout the whole negotiation process.
