In software projects, program evaluation and review technique (PERT) is frequently used to estimate the schedule of the uncertain projects. However, classic PERT does not allow the existence of loop in PERT graph, and assuming that all the activities time subject to the probability distribution. All these restrict the use of PERT. Firstly, by mapping PERT network to the Petri nets based model, this...
In the existing approaches for performance analysis of WorkFlow nets (WF-nets), there is much restrictive for the time distribution functions of the activities in the model. Because the firing delay of different transitions in the WF-nets may be based on different distribution conditions, this paper introduces Moment Generating Function (MGF). Firstly, this paper integrates the analysis approach for...
