摘要
阐述了事故发生的时序随机平稳性,采用最小二乘法进行相关分析,建立了事故频数与年序数之间的回归预测模型,应用事故预测模型,对某单位15年事故进行了相关分析与计算,预测了未来年度该单位可能发生的事故频数,及其预测区间.对该事故预测模型的应用进行了简单的说明.
The accident random stabilization is studied in this paper. Based on the least square method, a regressive prediction model between accident frequency and the year is established. Using this model, correlation analysis is done to the 15-year data of a factory, and the accident frequency of this factory in the coming year is predicted. The predicted accident frequency range has also been given. A brief explanation is made about the application of the accident prediction model.
