Supplying many scientific effective computing models, decision support ways and a lot of accurate reliable decision data, the DSS plays a critical part in helping engineering researchers to make correct decisions. Because the period for developing the DSS is relatively shorter, the new way improves the efficiency of establishing DSS greatly. It also makes the DSS of system structure more flexible and easy to expand.展开更多

The CAD system is developed based on the object-oriented approach. The application domain of hydraulic presses has been studied thoroughly. The engineering data and the design knowledge are organized in an object-oriented database. A case study has been selected to illustrate the usefulness of the object-oriented CAD system in real applications.展开更多

The integrating raster with vector methods of updating the basic land use/land cover map based on 3S technology is becoming one of the most important developing directions in 3S application fields, land-use and cover change fields over the world. It has been successful applied in two tasks of the Ministry of Land and Resources of China, and takes some benefit.展开更多
