Probabilistic network analysis for project completion time*
The paper deals with the probabilistic network analysis for project completion time for various networks. As the project completion time depends on the path with the longest total completion time of all the given paths, it is expressed as a function of various activity durations according to known activity precedence relationship in the present study. As all the activity durations are considered probabilistic in nature, the total completion time is also a probabilistic variable and the determination of that requires rigorous mathematical analysis. Rosenblueth's two point estimates scheme is used for this non-linear probabilistic analysis problem and the results are compared with Monte Carlo Simulation. Such a study is conducted for two different networks and the results compared very well for both sample problems, both for uniform and normal distribution of the random variables which are the activity durations and the activity precedence relationships in the present study.
