Distributed constraint-based optimized routing of interactions
A system for optimized routing of interactions, comprising media servers, a statistics server, a routing database, and a routing server. Upon receiving or initiating an interaction, a media server sends a route request message to the routing server, the statistics server receives event notifications from the media servers and computes one or more statistics, and the routing server executes, using statistical data from the statistics server and data from the routing database, a routing script comprising a constraint-based optimization process in response to the route request message.
1. A system for routing interactions, the system comprising:
a media server operating on a network attached computer and configured to handle interactions of one or more specific media types;
a routing server comprising a routing database and operating on a network-attached computer;
wherein upon receiving or initiating an interaction of a specific media type, the media server sends a route request message comprising at least an interaction identifier and a collection of interaction-specific data to the routing server;
wherein the routing server periodically executes, using data from the routing database, a routing script and sends routing instructions to the media server; and
wherein the routing script comprises at least the execution of a constraint-based optimization process that matches the plurality of interactions requiring routing to one or more of a plurality of resources that may handle interactions.
2. The system of claim 1 , wherein the constraint-based optimization process comprising the steps of:
(a) initializing parameters including global constraints; and
(b) for each time increment:
(i) computing a time to wait for each resource;
(ii) discarding resources whose time to wait exceeds a configured threshold;
(iii) determining a wait time for each interaction n;
(iv) computing an indicia of cost for a plurality of resource-interaction pairs;
(v) constructing a problem matrix; and
(vi) optimizing interaction distribution subject to problem constraints.
3. A method for constraint-based optimization of routing of interactions, the method comprising the steps of:
(a) receiving or initiating a plurality of interactions at a media server stored and operating on a network-attached computer;
(b) sending a plurality of route requests from the media server to a routing server stored and operating on a network-attached computer, the routing server comprising a routing database;
(c) periodically executing, at the routing server and using data from the routing database, a routing script, wherein the routing script comprises at least the setup and execution of a constraint-based optimization process that matches the plurality of interactions requiring routing to one or more of a plurality of resources that may handle interactions; and
(d) sending a plurality of routing instruction messages from the routing server to the media server comprising at least an interaction identifier and a target resource.
