摘要: 为降低大型集贸市场的火灾风险,探究大型集贸市场火灾致灾因素,运用解释结构模型分析各因素间的内在联系。结合交叉影响分析法和马尔可夫链预测构建定量分析模型,获得火灾致灾因素的稳态概率矩阵。研究结果表明:马尔可夫修正概率更加准确,该模型可明确大型集贸市场火灾致灾因素排查和管控的重点。

Abstract: In order to reduce the large fair fire risk, explore its fire cause factors, the interpretation structure model is used to analyze the inner link and hierarchical relationship among various factors. Combining cross impact analysis method and Markov chains forecasting model, a quantitative analysis model is built to get the steady- state probability matrix of the fire cause factors. The results show that the Markov probability is more accurate, the model can clarify the key screening and controlling points of large fair fire cause.

Key words: cross- impact analysis, Markov chains forecasting method, interpretative structural modeling, large fair, fire risk analysis
