By analyzing the disadvantages of traditional fault calculation software, and utilizing the thinking of oriented object design with the visual component technology and the COM mode, this paper designs and develops the graphical power system fault calculation software and the integrated management system.

This paper which uses the visual component technology and the design method of object-oriented,designs and develops a graphical system named SCADA based on visual component technology,realizes free drawing of wiring diagram in SCADA system.

Study on the First-Round Delphi Investigation of Technology Forecasting in the Hi-Tech Industry;

A case study is presented to show the process of application of TRIZ to technology forecasting.

Being emphasized on the base of difference between technology forecasting and technology foresight,it makes an instructive probe into technology foresight and economy sustainable development.

The situation of study and application on the prediction technology of coal and gas outburst was summarized,effects obtained and current problems were discussed,and countermeasures to advance the technology in the future were put forwarded.

The paper firstly stated the present status and development tendency of coal and gas outburst prediction technology in China.

Based on the current situation of Chinese telecommunication industry and using the number of regular telephone users as an example,the application of qualitative and quantitative prediction technology to the decisionmaking of Chinese telecommunication service development is discussed.
