Query: On simulating nondeterministic stochastic activity networks   In this work we deal with a mechanism for process simulation called a
NonDeterministic Stochastic Activity Network (NDSAN). An NDSAN consists
basically of a set of activities along with precedence relations involving
these activities, which determine their order of execution. Activity durations
are stochastic, given by continuous, nonnegative random variables. The
nondeterministic behavior of an NDSAN is based on two additional possibilities:
(i) by associating choice probabilities with groups of activities, some
branches of execution may not be taken; (ii) by allowing iterated executions of
groups of activities according to predetermined probabilities, the number of
times an activity must be executed is not determined a priori. These properties
lead to a rich variety of activity networks, capable of modeling many real
situations in process engineering, project design, and troubleshooting. We
describe a recursive simulation algorithm for NDSANs, whose repeated execution
produces a close approximation to the probability distribution of the
completion time of the entire network. We also report on real-world case
studies.
