A Risk Evaluation Method for the High-Technology Project Investment Based on ET-WA Operator with 2-Tuple Linguistic Information

With respect to multiple attribute decision making problems with linguistic information of attribute values and weight values, a decision analysis is proposed. Then, a method based on the ET-WA operator for multiple attribute decision making is presented. In the approach, alternative appraisal values are calculated by the aggregation of 2-tuple linguistic information. Thus, the ranking of alternative or selection of the most desirable alternative(s) is obtained by the comparison of 2-tuple linguistic information. Finally, a numerical example with risk evaluation of high-technology is used to illustrate the applicability and effectiveness of the proposed method.
