This paper derives the optimal cycle time and total cost of an EPQ model with a variable rate of deterioration and mixed demand pattern. Demand is inventory dependent during the inventory buildup time and constant demand has been used for during an inventory depletion period. The rate of deterioration is changing after particular time period. A numerical example has been provided to validate the model. The result of sensitivity analysis indicated that total cycle time and cost are sensitive to production rate, increase in deterioration rate and demand rate.
