Research on fire risk factors of cotton in railway transportation

Cotton plays a very important role in the economy of China and wellbeing of millions of people depends upon its good production and utilization in the country. Therefore, the railway transportation of cotton is becoming more and more important. In this paper, we analyze main factors causing cotton fire according to historical information. We first calculate the relative importance of all features for the risk of catching fire with the clustering method. Then, we calculate the risk rate of each main factor. The experiments show that the inside temperature of cabin, and the humidity and inside temperature of cotton pack are the top three factors that may cause fire.
