The thesis firstly describes the background of DSS, the definition of DSS, the architecture of DSS and the development of DSS. Then the background, the conception, the architecture and the data structure of data warehouse are introduced. The relation between data warehouse and DSS is discussed , the architecture of DSS based on data warehouse is established. Based on the discussed above, the thesis studies the scheme of DSS based on data warehouse in pumping station .Lastly, ant algorithm is introduced, and is applied to solve the pratical problems which are optimal distribution of load in pump station. |
