For last 25 years we use simplified but very efficient method of risk simulation that we call 3 scenarios method.
It is based on creation and analysis of optimistic, most likely and pessimistic versions of project schedule.
Look at this presentation
http://www.spiderproject.com/images/img/pd...%20Analysis.pdf for more details.
In some projects we use this way of risk simulation in parallel with Monte Carlo. The results do not differ much. Though Monte Carlo simulation is recognized as most scientific and reliable method it is based on initial data of very low quality and so its advantage is questionable. In any case both methods provide similar results but three scenarios is simple and fast, Monte Carlo requires much more time and efforts.
Let me know if you will have any questions.
