WS-BPEL Extension for People (BPEL4People) introduces human activity to Web Services Business Process Execution Language (WS-BPEL/BPEL). Some works have been done on the performance verification of WS-BPEL, but there aren't works on the performance verification of WS-BPEL4People. In this paper, we propose a model method for the transformation of WS-BPEL4People/BPEL4People intoGeneralized Stochastic Petri Nets (GSPN) and this way evaluate its performance.During the transformation, Petri Net is used to model BPEL activities and the human activity of a human task.Then, by validating the generated model, some potential problems with performance of WS-BPEL4People can be detected.
