| Abstract: | In this paper,gray system theory is used in data analysis of building which was observed for several months.Because of the uncertainty of observation period,unequal-step GM（1,1） model is used to process the data,least square is used to get the parameters of unequal-step GM（1,1） model.Test methods are given to inspect the accuracy of this model.According to an example,data process is displayed.Comparing these results to those processed by the traditional GM model,the unequal-step GM（1,1） model is better than the traditional GM model in accuracy,fitting data and forecasting data. |
