作者：

Highlights：

• A SIR epidemic model with fuzzy parameters is proposed.

• Existence analysis of fuzzy epidemic model is given.

• Fuzzy reproduction number is computed in this paper.

• A structure preserving numerical method is used for the solution of fuzzy epidemic model.

• Comparison of the proposed method with other methods is also presented.
