Abstract : For production systems, risks may have serious effects that may threaten their performance. Nevertheless, we cannot estimate the degradation that a risk may cause to system performance, since risk analysis methods found in the literature do not allow simulating the behavior of the system in degraded mode. In this paper, we propose a translation method that helps to convert a model based risk analysis framework, which is the Function, Interaction, Structure (FIS) model, into an executable model based on Predicate-Transition, Prioritized, Synchronous (PTPS) Petri Net, which is a new class of Petri Net (PN)s that we defined for simulation purposes. Using the proposed conversion method, we will be able to obtain a model capable of simulating the behavior of a production system in degraded mode. Furthermore, quantitative indicators can be generated to help risk analyst to quantify the performance degradation. To obtain degraded mode simulation model, we start by performing risk analysis of the system using FIS framework. Then, the obtained model from this risk analysis is translated automatically using algorithms into a PTPS Petri Net model. Finally, using a simulator, the PTPS PN model is executed in order to visualize the behavior of the system in degraded mode.
