人们在进行震害调查、烈度评定、震害预测等工作中,无不要涉及建筑物的破坏等级。这些等级一般都是用语言给出的,比如“基本完好”、“中等破坏”、……等等。这是典型的模糊概念,无论从工程破坏的情况来定义它,还是从修复难易的程度来定义它,甚或用修复费用等经济指标来定义它,都是无法做到明确无误、清晰明白和界线分明的。因此,运用模糊数学来研究和处理与之有关的问题就是十分自然的。为了对于涉及震害等级的震 People in the earthquake damage survey, intensity assessment, earthquake damage prediction work, all without exception, involving the destruction of the building level. These levels are generally given in words, such as “basically intact”, “moderate damage”, ... and so on. This is a typical ambiguous concept. It can not be defined clearly and clearly whether it is defined in terms of engineering damage, defined from the ease of repair, or even from economic indicators such as repair costs Clear line. Therefore, the use of fuzzy mathematics to study and deal with the problems related to it is very natural. In order to deal with earthquake damage level
