The present disclosure relates to systems and methods for operating an online on-demand service platform. The systems may perform the methods to: determine one or more recommendation rules for one or more activities for recommending to one or more candidate users; determine, for each of the one or more activities, one or more preset objects for the activity to achieve on the one or more candidate users; determine, for each of the one or more activities, a completion probability that each of the one or more candidate users will complete the one or more preset objects of the activity; and determine, for each of the one or more activities, at least one target user from the one or more candidate users to send a notice of the activity based on the one or more completion probabilities and the one or more recommendation rules.

Systems and methods for activity recommendation

The present disclosure relates to systems and methods for searching for a route. The systems may perform the methods to obtain route information of a first route; encode the route information of the first route into a first code based on a target model; access a target database in at least one storage medium, wherein the target database includes a plurality of candidate codes encoded through the target model from a plurality of candidate routes; identify, from the plurality of candidate codes, a second code based on the first code, the second code being associated with at least one second route; and send information associated with the at least one second route to a receiving device.

Systems and methods for route searching

The present disclosure relates to systems and methods for vehicle management. The systems may perform the methods to obtain information associated with a vehicle in a first time period; determine an income value associated with the vehicle in a second time period based on the information associated with the vehicle; determine a cost value associated with the vehicle in the second time period based on the income value and the information associated with the vehicle; and generate a recommendation as to whether to discard the vehicle based on the income value and the cost value.
