During the interval ([0, t_1],) the inventory level decreases due to combined effects of deterioration and demand and the inventory level drops to zero during the time interval ([0, t_1].) During the interval ([t_1, T],) shortages occur which are partially backlogged.
At time (t=mu ), the depletion occurs due to the combined effect of demand and deterioration and finally comes to an end at time (t=T).
From Fig. 1, it can be seen that the depletion of the inventory occurs due to the combined effects of demand and deterioration during the time interval (left[ {t_{1},t_{2} } right]).
