Considering this, this paper introduces shipping into the multi-period perishable inventory problem. Online sequential prediction algorithm of aggregating expert advices is used to study the competitive ordering strategies. Based on stationary expert advices, the online ordering strategy is built. Moreover, the conclusion that the cumulative gain of the online ordering strategy is as large as that of the best expert advice is proved. Numerical examples are further presented to sh
