An EOQ model for perishable items under stock-dependent selling rate and time-dependent partial backlogging

In the present paper, we extend Padmanabhan and Vrat's model by proposing a time-proportional backlogging rate to make the theory more applicable in practice. The existence and uniqueness of the solutions of the relevant systems are examined. Subsequently, a numerical example is presented to illustrate the application of developed model.
