摘要：
In this paper, a fuzzy triangular approximation using alpha-weighted valuations is introduced and the nearest approximation by the minimization technique is obtained, such that the computational complexity is less than that in Abbasbandy and Amirfakhrian 2006. Moreover, we investigate some reasonable properties of the alpha-weighted triangular approximation.
