Both seasonal demand r and total demand R in the production inventory model are difficult to estimate precisely to actual r(0) and R(0) values, respectively. Hence, we will set the membership grade at r(0) and R(0) in an interval [lambda, 1], 0 < lambda < 1, and then, obtain the interval-valued fuzzy sets (r) over tilde and (R) over tilde, respectively. For each production quantity period q, we can obtain the fuzzy total cost G(q) ((r) over tilde, (R) over tilde) and determine the defuzzification of G(q) ((r) over tilde, (R) over tilde) as the estimate of the total cost. This paper presents production inventory model uncertain problems that would be helpful in the real world.
