In this paper, we presented the multi items inventory control model that its objective is minimizing total cost. This
model is formulated under four constraints consist of storage spaces, budgetary, allowable shortage quantities and
periodic order quantities. Two latest constraints is interval typically. In presented model, shortage is allowable and leadtime
is zero. The parameters such as demands, costs (including: setting, holding, shortage) and constraints resources are
fuzzy. Type of fuzzy numbers in demand & cost is triangular and numbers of constraints resources are positive
trapezoid typically. In solution methodology, first we converted the cost objective function to three objective functions
and then reduced fuzzy constraints to crisp constraints via defuzzification. Then we solved the resulted crisp multi
objectives using Fuzzy Non Linear Programming (FNLP). Finally we presented a numerical example to solve and
describing model applying Lingo software package.
