Abstract: In B2C environment,the dynamic pricing was the key method of Internet retailers for solving insufficient capacity of delivery time slot.To gain maximum expected profit in B2C,under the randomness of customers' online time slot choice,the Logit-based probability choice model was introduced,and the multi-time slots with single substitution problem was discussed with the availability and unavailability of time slots.The expected profit model was proved and numerically analyzed to determine the optimal polices of delivery time slots.Thus the following conclusion were drawn: with the fixed capabilities and increasing order volume,the gains under substitution of time slots was higher than that with no substitution;the gains under the unavailability of unpopular time slot was higher than that under the unavailability of popular ones,so it was better for the online retailing to take methods to extend the opening time of popular time slots,but in both cases the income increased more and more slower,which indicated that the unavailability of time slots could cause negative effects;the higher expected utility of time slot was the higher pricing of time slots and greater income online retailers gains.
