An undifferentiated study between fuzzy stock followed by deficiencies and deficiencies followed by fuzzy stock under exchange credit strategy.

This model deals with an undifferentiated fuzzy stock followed by deficiencies and deficiencies followed by fuzzy stock with quadratic demand rate. The degradation rate is represented by Weibull distribution involving two parameters. Both models made use of a fixed exchange of the retailer's credit period from the provider. The model is used to find an ultimate solution in fuzzy environment such that the entire expenditure cost is reduced. The signed distance approach is being used for fuzzification of the proposed model using triangular fuzzy integers. The validation of the proposed model is demonstrated numerically.
