Closed loop performance management for service delivery systems

A computer program product for dispatching service request, the computer program product comprising:

• a computer readable storage medium;
• program instructions stored on the computer readable storage medium to identify a service request class having a largest control error from a plurality of service request classes;
• program instructions stored on the computer readable storage medium, responsive to identifying the service request class having the largest control error from the plurality of service request classes, to identify whether a service request priority of the service request class having the largest control error has been previously increased;
• program instructions stored on the computer readable storage medium, responsive to identifying that the service request priority of the service request class having the largest control error has not been previously increased, to increase the service request priority of the service request class having the largest control error to form an updated priority;
• program instructions stored on the computer readable storage medium, responsive to identifying that the service request priority of the service request class having the largest control error has been previously increased, to refrain from increasing the service request priority of the service request class having the largest control error to form the updated priority;
• program instructions stored on the computer readable storage medium, to determine whether a service request priority for each of the plurality of service request classes has been previously increased;
• program instructions stored on the computer readable storage medium, responsive to determining that the service request priority for each of the plurality of service request classes has been previously increased, to reset the service request priority for each of the plurality of service request classes to an original service request priority;
• and
• program instructions stored on the computer readable storage medium to dispatch service requests for the plurality of service request classes in a next control iteration based upon the updated priority.
