An executable software project management model by beta-distributed stochastic Petri nets
Chun-suk Park, Gang-soo Lee, Jung-Mo Yoon · 2002
This paper proposes a new software project time and cost management model using a beta-distributed stochastic Petri nets (BSPN), which is an integrated model of PERT and Petri nets. A beta-distributed transition, from PERT, is adapted for modeling the uncertainty of time and cost of a software project. Structural properties of the project are analyzed from structure of the BSPN. Behavioral characteristics of the project, such as time and cost, are analyzed using a chronological reachability graph of BSPN.>
