In this study, we find that there are two problems when applying the techniques of discretization to obtain an approximated probability density function of the project completion time in stochastic activity networks. Namely, first, there exists neither exact data structure nor systematic scheme for the computer programming when applying the techniques of discretization; and second, error may arise from assuming independency between sub-paths in the activity network.
