Patent ID: 7756690

Claim:
A method for supporting performance prediction of a system having at least one external interactor, comprising: running the system under test in a pre-deployment phase with a predefined number of items to be serviced by the at least one external interactor for input into the system; receiving an arrival rate of items arriving at the at least one external interactor for servicing and input to the system, wherein the arrival rate represents an arrival rate of items for the system during operation under full load in a deployment phase; calculating a service time that the at least one external operator takes to service one of the predefined number of items; selecting a queuing model based on the received arrival time and the calculated service time; applying the selected queuing model to calculate a queue length of items for servicing at the at least external interactor based on the received arrival time and the calculated service time; and providing the calculated queue length and the calculated service time for performance prediction of the system.
