Abstract
This paper establishes the network marketing performance evaluation index system followed the principles of "scientific, objective, systematic, feasibility and stability". Then use interval-valued intuitionistic fuzzy sets OWA (Ordered Weighted Averaging) operator to calculate the evaluation value. The reason of this paper use interval-valued intuitionistic fuzzy sets is some index value is not necessarily a certain number in real life, the interval-valued intuitionistic fuzzy sets can describe some parameter values in greater detail; Next OWA operator is used to calculate the e-marketing performance evaluation value of various enterprises, then compare the evaluation value and put forward the corresponding strategy. Finally enumerated instances to validate the method adopted by this paper used in the enterprise e-marketing performance evaluation is feasible and effective.
