In this paper we have developed an order level inventory system for time dependent linearly deteriorating items with decreasing demand rate. In developing the model we have assumed that the production rate and the demand rate are time dependent. We have developed two EOQ models for without shortage case and with shortage case. Our results are being illustrated with numerical examples for both the models and sensitivity analysis has been carried out to show the effect of changes in the parameter on the optimum total average cost.
