The purpose of this study was to evaluate the severity of the incompatibility of class 4.3 chemicals in the compatibility and segregation chart of an Australian standard by a fuzzy TOPSIS method. Five main criteria were selected to determine the severity of chemical incompatibility, and the general incompatibility of class 4.3 chemicals with 11 classes of chemicals (alternatives) was quantified. By determining the type of consequences of incompatibility the class in pairs, a more practical chart was proposed. The class of self-igniting materials had the highest intrinsic incompatibility. The lowest intrinsic incompatibility belonged to the corrosive substances class. The consequences of each inconsistency were presented in the form of a visual chart. When the importance of criteria and the ranking of alternatives cannot be expressed using numerical values, the use of verbal variables to express them is very appropriate. The use of the fuzzy TOPSIS technique is very appropriate and flexible.

提出一种基于FTOPSIS的危险品不相容严重程度评估新方法：以4.3类为例

本研究的目的是通过模糊 TOPSIS 方法评估澳大利亚标准的相容性和隔离图表中 4.3 类化学品不相容性的严重程度。选择了五个主要标准来确定化学不相容性的严重程度，并对 4.3 类化学品与 11 类化学品（替代品）的一般不相容性进行了量化。通过确定不兼容的后果类型，成对的类，提出了一个更实用的图表。自燃材料类别具有最高的内在不相容性。最低的内在不相容性属于腐蚀性物质类。每个不一致的后果都以可视化图表的形式呈现。当标准的重要性和备选方案的排名不能用数值来表达时，用语言变量来表达是非常合适的。模糊TOPSIS 技术的使用是非常合适和灵活的。
