“…Xu [51] studied the decision making problem and proposed a multi-attribute decision making method based on the similarity degree of fuzzy numbers. In recent years, D-S theory is often combined with fuzzy set theory to construct the target model and handle uncertain problems [52], [53]. As a powerful fuzzy number, triangular fuzzy number is commonly applied in the practice due to its simplicity and practicability [54].…”

Dempster-Shafer evidence theory (D-S theory) is a developing theory to solve the uncertain problems and it has an important impact on many fields such as information fusion, expert systems, and machine learning. One of the main points of D-S theory is about how to generate a reliable basic belief assignment. Furthermore, the data collected from the multi-sources may be influenced by noise or other factors which cause conflicts in practical applications. Since the fuzzy number is useful to construct the target model for generating basic belief assignments, in this paper, an improved method to obtain basic belief assignment is proposed based on the triangular fuzzy number and k-means++ algorithm. First, the k-means++ clustering method is used to construct the target model. Then, the difference degree between the target model and sample model is calculated to generate the initial basic belief assignments. After that, the conflicts will be resolved by using the discount coefficient method. Finally, Dempster's combination rule is used to combine initial basic belief assignments to obtain the final result. The applications in recognition problems of the Iris data set and Wine Quality data set illustrate that the proposed method is effective to generate the basic belief assignments and keeps a high recognition rate even under a noisy environment.
