A new decision making method based on Z-decision-making trial and evaluation laboratory and ordered weighted average and its application in renewable energy source investment

Decision-making methods are widely used in renewable energy source (RES) investment. In practical applications, various conditions need to be considered during the decision-making process, such as uncertainty and reliability of information, dependence among criteria, different risk preferences decision makers. However, there is currently a lack effective consideration all these conditions. this article, new method based on Z-DEMATEL maximal entropy OWA operator proposed, where Z-number characterize trial evaluation laboratory (DEMATEL) technique, ordered weighted average (OWA) deal with preference, respectively. The application example RES investment discussions show effectiveness advantages proposed method.
