Abstract


Interval-valued fuzzy set is the expansion of the fuzzy sets , interval numbers and fuzzy sets theoretically , combined with the advantages of interval numbers and fuzzy sets , more detailed description of the decision-making information to avoid decision-making information losses. In recent years , the research for interval fuzzy sets are mainly concentrated in the basic theory , most scholars focused on several aspects Triangle interval fuzzy . Inspired interval fuzzy set based on the use of interval-valued trapezoidal fuzzy numbers to represent the manifestation of the property values ??in the majority decision , and the interval fuzzy sets based on the basic operations of interval-valued trapezoidal fuzzy sets law , as well as the distance measure formula , a sort of interval-valued trapezoidal fuzzy number . At the same time , the paper TOPSIS method based on interval-valued trapezoidal fuzzy numbers and fuzzy numbers based on interval-valued trapezoidal OWGA operators method when the attribute value of interval-valued trapezoidal fuzzy numbers multi - attribute decision making problems . Shortly thereafter, the establishment of the e-commerce risk assessment index system , and the use of two new methods of e-commerce enterprise project risk evaluation to prove the validity of the evaluation system and evaluation methods . Concluded not only beneficial to the person in charge of the e-commerce businesses understand the potential risk and risk to develop the project size , the prevention of risk also has certain reference value .
