Abstract: In 1995,Padmanabhan and Vrat presented inventory models for deteriorating items with a constant theoretical demand rate and stock dependent selling rate.Based on this result,in 2000,Kun-Jen Chung,Peter Chu and Shaw-Ping Lan devoloped the necessary and sufficient conditions of the existence and uniqueness of the optimal solutions of the profit per unit time functions without backlogging and with complete backlogging.Actually,the theoretical demand rate must not be constant,it may be linear function or exponential function of other more complex functions of time.This paper puts forward an EOQ model when theoretical demand rate is a linear time-varying increasing function without backlogging and with complete backlogging,discusses the existence and uniqueness of optimum solution without backlogging.The theoretical evidence is provided for the inventory system to make management decision.

Key words: deterioration, stock dependent selling rate, theoretical demand rate, linear time-varying increaing function, EOQ Model
