Abstract: A computational instance may contain queues configured to hold work items. The work items may be representations of user submissions requesting actions from a plurality of agents. The computational instance may also contain computing devices configured to: (a) obtain a set of assignment rules that specify mappings between (i) respective selection criteria for the assignment rules, and (ii) one or more candidate agents from the plurality of agents that can be assigned to address the work items with content that match the respective selection criteria, (b) read, from the queues, a work item corresponding to a user submission, (c) iterate through the assignment rules according to an ordering until a particular assignment rule with associated selection criteria that matches content of the work item is found, and (d) assign the work item to a particular agent from the one or more candidate agents.

Abstract: An embodiment may involve persistent storage containing definitions of a set of queues and a set of servers, and wherein the servers are respectively associated with deactivation times. One or more processors may be configured to: (i) identify, by an assignment engine, an incoming request in a particular queue, wherein the incoming request is ready for assignment to one of the servers; (ii) determine, by the assignment engine and based on data associated with the incoming request, an expected duration for servicing of the incoming request; (iii) calculate, by the assignment engine and based on the deactivation times, times remaining in service for each of the servers; (iv) select, by the assignment engine and from the servers, a particular server that has a time remaining that is greater than the expected duration; and (v) assign, by the assignment engine, the incoming request to the particular server.
