Abstract

Inventory models in which the time period of sales is a decision variable are considered in fuzzy environments. Arrival of customers and the number of customers in the planning period are both random. Several cases of the model with one or more of the components fuzzy are discussed. Models with trapezoidal and triangular fuzzy numbers are considered. Optimum policy of the models are derived and numerical examples are provided in order to ascertain the sensitiveness in the decision variable with respect to fuzziness in the components.
