Abstract

Event tree is a powerful tool in delineating accident scenarios as representatives of classes of events for PSA purposes. It, however, is a modelling technique which hardly gives an adequate account of dynamic processes interacting with systems' states, that are those an operator is in reality confronted with. Petri Nets or other similar approaches model fairly well timed sequences of events: they fail again in giving account of the process physics. On the contrary, the DYLAM technique is shown to present significant advantages especially for establishing stochastical models of dynamic systems; and, therefore, is a powerful aid for the design of decision support systems to assist the operator in the control of hazardous processes.
