This paper examines the DYLAM approach in the framework of Monte Carlo (MC) simulation. It shows that the DYLAM way of handling stochastic transitions is a biased Monte Carlo in which proper Dirac delta functions are used instead of the true failure probability density functions. The cumulative distributions turn out to be step functions. In this way, the forced collision variance reduction technique is applied. The stochastic feature of Monte Carlo simulations is practically lost at this point; this has the advantage of reducing the number of histories.
