Vague Sets Evaluation and its Application Based on TOPSIS Idea in Technological Innovation
In order to get the idea technological innovation scheme,the scheme selection is studied in the paper.From the actual situation,a group of evaluation index which included in the strength,the potential and the external environment about technical innovation scheme is selected.With the Vague set theory,the evaluation value of any innovation scheme is defined by the concept of Positive-ideal solution and Negative-ideal solution of TOPSIS.With the concept of distant in Vague set theory,a new evaluation method is built to get a satisfied solution.This method reflects the advantages of Vague set theory which describe the uncertainty,meanwhile,the basic criteria for project evaluation is meet by the TOPSIS idea.The idea and method not only take a new application field to the Vague set study,but also get a new idea and method to the technological innovation study.
