The Prior Topics Selection Methods Based on the Delphi Survey in Technology Foresight

Technology Foresight rose to the fore in the 1990s in the context of national technology foresight program.The technology exercises are largely a matter of research priorities and ST planning.The Delphi method is one of the most popular tools in the technology foresight.Generally speaking,the Delphi method evaluates the topics with several indicators,such as importance,feasibility,difficulties of realization,research level,and forecasted time and so on.However,it is very difficult to select out the topics with excellent in each indicator.Therefore,this paper raises a method of synthetic ranking for topics with multi-attribute decision method.
