| 摘 要： | 采用FTP-图(频繁时序图)的时间序列方法对流程企业中的实际运行数据进行数据挖掘,首先给出基于拓扑关系的时间序列的定义,分析FTP-图连接、候选TP-图剪枝和采用哈希树的候选TP-图计数方法,然后采用模糊理论找出偏离常规运行状态的参数点并模糊化,采用时间窗对参数离散处理,得到时间序列数据库.根据Apriori算法原理,提出基于FTP-图的时间序列分析算法并编程实现,起到对设备故障预警和生产优化的决策作用.

| Abstract: | To monitor and optimize process industry's production,the large history database are analyzed by time sequential pattern based on FTP-graph(frequent time pattern graph).Firstly,the topological relations of the time sequential patterns are expounded.FTP-Graph algorithm is studied by joining frequent temporal graphs,subtracting candidate temporal graph and scanning process instances in database.The exceptional equipment parameters are found and fuzzed by fuzzy theory.The parameters in real-time database are scattered by time-window approach.The time sequential database is given.According to Apriori algorithm,the FTP-Graph algorithm is studied and implemented in process industry. |
