Word trajectories based on interval type-2 fuzzy method

This paper presents the numerical calculation procedure of the word trajectories based on the interval type-2 fuzzy method. Firstly, the interval type-2 fuzzy decomposition theorem is employed to calculate the function of input words (interval type-2 fuzzy sets). Then, the numerical procedure of words trajectories is presented, which illustrates the dynamic evolution orbits of the studied social system. Lastly, a few interesting numerical examples evaluates our proposing method and the numerical orbits are also used to perform comparison with their word counterparts.
