Abstract

A method and apparatus are provided for performing staffing-based percentage-allocation routing using real-time data. According to one aspect of the present invention, transaction allocation is determined using both scheduled and actual handling resources. Actual handling resources associated with each of several transaction processing systems, such as automatic call distributors (ACDs), are measured at times t and t+n. Scheduled handling resources associated with each of the transaction processing systems for times t and t+n are also identified. Then, estimated handling resources are calculated for each of the transaction processing systems for time t+n based upon the actual handling resources and the scheduled handling resources. Finally, based upon the estimated handling resources, transaction allocations for each of the transaction processing systems are determined. According to another aspect of the present invention, a virtual call center is provided. The virtual call center includes a wide area network (WAN), multiple call centers coupled to the WAN, and an allocation controller coupled to the WAN. Each of the call centers includes a transaction processing system. The allocation controller is configured to calculate allocation sets for one or more forecast periods based upon scheduled staffing levels and actual staffing level information received from the transaction processing systems. The allocation sets include percent allocations for each of the transaction processing systems. The allocation controller is additionally configured to balance call distribution among the transaction processing systems by uploading the allocation sets to an inter-exchange carrier interface.

Claims

1. A method of distributing transactions among a plurality of transaction processing systems, the method comprising the steps of:

identifying actual handling resources associated with each of a plurality of transaction processing systems at time t;

identifying scheduled handling resources for each of the plurality of transaction processing systems at time t+n;

calculating estimated handling resources for each of the plurality of transaction processing systems at time t+n based upon the actual handling resources and the scheduled handling resources; and

causing transactions to be distributed among the plurality of transaction processing systems based upon the estimated handling resources for each of the plurality of transaction processing systems.

2. The method of claim 1, wherein the transactions comprise telephone calls and wherein the transaction processing systems comprise automatic call distributors.

3. The method of claim 1, wherein the transactions are received over the Internet and wherein the transaction processing systems comprise web servers.

4. A method of distributing transactions among a plurality of transaction processing systems, the method comprising the steps of:

determining a ratio of actual handling resources associated with each of a plurality of transaction processing systems to scheduled handling resources for each of the plurality of transaction processing systems at time t;

calculating estimated handling resources for each of the plurality of transaction processing systems at time t+n based upon the ratio and scheduled handling resources for each of the plurality of transaction processing systems at time t+n; and

causing transactions to be distributed among the plurality of transaction processing systems based upon the estimated handling resources.

5. A method of distributing transactions among a plurality of transaction processing systems, the method comprising the steps of:

determining a relationship between actual handling resources associated with each of a plurality of transaction processing systems and scheduled handling resources for each of the plurality of transaction processing systems;

calculating estimated handling resources for each of the plurality of transaction processing systems at time t based upon the relationship and scheduled handling resources for each of the plurality of transaction processing systems at time t; and

causing transactions to be distributed among the plurality of transaction processing systems based upon the estimated handling resources.

6. The method of claim 5, wherein the step of determining a relationship between actual handling resources associated with each of a plurality of transaction processing systems and scheduled handling resources for each of the plurality of transaction processing systems comprises determining a ratio of the actual handling resources to the scheduled handling resources.

7. The method of claim 6, further comprising the step of applying a weighting factor to the actual handling resources and the scheduled handling resources.

8. The method of claim 6, further comprising the step of determining call rate capacities based upon the estimated handling resources and desired service level and/or cost constraints.

9. The method of claim 8, wherein the call rate capacities are adjusted for direct traffic to the plurality of transaction processing systems.

10. The method of claim 6, wherein transaction allocation among the plurality of transaction processing systems takes into account user-defined, fixed allocation percentages associated with one or more of the plurality of transaction processing systems.

11. The method of claim 5, wherein the step of determining a relationship between actual handling resources associated with each of a plurality of transaction processing systems and scheduled handling resources for each of the plurality of transaction processing systems comprises determining a trend of the deviation of the actual handling resources from the scheduled handling resources.

12. The method of claim 11, wherein the estimated handling resources for time t are represented by the following equation:
