Fast time ordinal number algorithm is a local data mining algorithm for multi-objective optimization,and it is easy to fall into local optimal when dealing with complicated data. In order to improve the global data mining ability of the algorithm,a fast time series data mining algorithm based on grey system theory is proposed. Firstly,the algorithm uses the fast time sequential data mining algorithm for data processing. Then,in order to get more ideal results,the grey system theory is used to do greedy iterative in the process of data mining. Finally,through the experiment simulation,and compared with the fast timing algorithm and the multidisciplinary design optimization（ MDO） algorithm,the results show that the data mining algorithm proposed in this paper has better global optimization ability,and the data mining effect is better.
