In this paper,a fuzzy inventory model for deteriorating items with time varying demand and shortages under fully backlogged condition is formulated and solved.In which demand increases with time.Shortages are allowed and fully backlogged.Fuzziness is introduced by allowing the cost components(holding cost,shortage cost,etc.),demand rate and the deterioration.In fuzzy environment,all related inventory parameters are assumed to be pentagonal fuzzy numbers.The purpose of this paper is to minimize the total cost function in fuzzy environment.Graded Mean Representation method is used to defuzzify the total cost function and the results obtained by this method are explained with the help of a numerical example.Sensitivity analysis is also carried out to explore the effect of changes in the values of some of the system parameters.
