摘　　要：知识约简是粗糙集理论的核心问题。首次尝试将这一概念用于建筑物震害预测工作中,结合震害预测工作的实际,提出了一种基于属性重要性的近似相对约简算法,并通过实例验证了其可行性。所述研究具有理论和现实意义,对今后进行有关抗震防灾工作具有很好的应用价值,并为开展震害预测工作提供了新的研究思路和手段。Reduction of knowledge is the core of rough set theory. This paper attempts to apply the concept to seismic damage prediction firstly, bring forward an approximate algorithm based on property weightiness for reduction of knowledge in view of seismic damage prediction, and finally use an example to validate its feasibility. The work of the paper has academic and practical meaning, and has an available value in earthquake resistance, as well as provides a new insight and tool for developing seismic damage prediction.
