Knowledge management performance evaluation based on triangular fuzzy number and the theory of knowledge cycle

In order to express the differences between subjective judgments and real results and reflect the dynamic process of knowledge management performance evaluation, the paper bases on the triangular fuzzy number and knowledge cycle theory to construct a knowledge management performance evaluation index system, with knowledge acquisition, knowledge sharing, knowledge utilization and knowledge innovation as its foundation. The paper summarizes the weights of each index with the theory of triangular fuzzy number and describes how to evaluate the knowledge management performance through the observation of knowledge management performance index in detail. The effectiveness of this method is also illustrated by the empirical analysis.
