A note on the reasonableness of PERT hypotheses
In this paper the expression for the mean in the PERT method is considered. This mean involves a parameter k, that sometimes has been set to 4. Insisting on the similarity between the beta and the normal distributions, certain hypotheses are proposed that lead to k necessarily being exactly 4. More speci6cally, by using the moments of the second and fourth orders, it is shown that the usual bet...

متن کاملPert 21
More than half a century after the debut of CPM and PERT, we still lack a project scheduling system with calibrated and validated distributions and without requiring complex user input. Modern decision support systems (DSS) for project management are more sophisticated and comprehensive than PERT/CPM. Nonetheless, in terms of stochastic analysis, they show insufficient progress. PERT 21 offers ...
متن کاملInterdiction Games on Markovian PERT Networks
In a stochastic interdiction game a proliferator aims to minimize the expected duration of a nuclear weapons development project, while an interdictor endeavors to maximize the project duration by delaying some of the project tasks. We formulate static and dynamic versions of the interdictor’s decision problem where the interdiction plan is either pre-committed or adapts to new information reve...
متن کاملDynamic interdiction games on PERT networks
In a PERT network interdiction game one player tries to get a project, represented as a PERT graph, finished as quickly as possible by allocating resources, expediting the project’s tasks and choosing between different technologies to use. At the same time a second player aims to maximally delay the project’s completion date by carefully choosing which tasks to disrupt. We develop a novel conti...
