Safety study of a control system, comparing markovian, fault tree and petri nets analysis

摘要

The purpose of this paper is to modelize the functional and the dysfunctional behavior of a system and to evaluate the occurrence probability of some envents inherent to this system, particularly an undersired event specified later. to achieve this goal three different approaches have been carried out: a Markovian analysis, a Fault Tree analysis and a third one based on Petri nets. the results respectively obtained arep resented, compared and commented.
