Abstract:	In this paper, we consider the inventory problem without backorder such that both order and the total demand quantities are triangular fuzzy numbers , and , respectively, where q1=q0−Δ1, q2=q0+Δ2, r1=r0−Δ3, r2=r0+Δ4 such that 0<Δ1<q0, 0<Δ2, 0<Δ3<r0, 0<Δ4, and r0 is a known positive number. Under conditions 0q1<q0<q2<r1<r0<r2 we find the membership function of the total fuzzy cost function and their centroid, then obtain order quantity q** in the fuzzy sense and the estimate of the total demand quantity.
