Abstract: An example computer-implemented method includes accessing service request data indicative of a service request, the service request having a service type and one or more service parameters. The method includes computing a complexity score associated with the service request based on the service type and the one or more service parameters. The method includes selecting a first courier of a plurality of candidate couriers based on the complexity score associated with the service request. The method includes outputting first instructions to a first courier device associated with the first courier. The first instructions are executable by the first courier device to cause a service assignment to be provided for display via a user interface of the first courier device, the service assignment indicating the first courier is to perform the service request.
