Abstract: A network computer system can implement a hierarchical selection process to fulfill a scheduled transport request. The hierarchical selection process can include a first selection process and a second selection process. The first selection process can include assigning a first transport provider to fulfill the scheduled transport request. The second selection process can be implemented at a specified time prior to the scheduled time and can include selecting a backup transport provider to service the scheduled transport request.

Abstract: A network computer system can implement a hierarchical selection process to fulfill the scheduled transport request. The hierarchical selection process can include a first selection process and a second selection process. The first selection process can include assigning a transport provider to fulfill the scheduled transport request. Additionally, the first selection process can include disassociating the transport provider with the scheduled transport request upon determining that the transport provider is unable to fulfill the scheduled transport request at the scheduled time. The second selection process can be implemented at a specified time prior to the scheduled time and can include selecting a backup transport provider.

Abstract: A network system can communicate with a user device and receive a set of request data for a scheduled request at a scheduled date and a scheduled time. The set of request data indicates a start location and a destination location for the scheduled request. The network system can record the scheduled request in a scheduling log, and implement a hierarchical selection process to fulfill the scheduled request.

Abstract: According to one general aspect, a method of presenting to a user a subset of applications that may be executed by a computing device is described. The subset of applications may be selected from a plurality of applications available an online marketplace for such applications. The method may include ranking the applications based on signals relevant to the relative desirability to the user of different applications, wherein at least one of the signals is based on information that is generated outside of the marketplace. The method may further include selecting the subset of applications based on their respective rankings. The method may also include presenting the selected subset to the user.
