Fault Tree Analysis of a Fire Hazard of a Power Distribution Cabinet with Petri Nets

Motivation of this study is to verify system safety analysis of HAVELSAN Peace Eagle Program developed hardware items for Ground Support Systems. A preliminary hazard analysis for each of the hardware developed items are performed and safety hazard analysis models are constructed with risk assessment of hazards based on their probability of occurrences for future operational and maintenance activities. An example for this kind of analysis the system safety fault tree analysis model of a Ground Support Segment Mission Simulator subsystem Power Distribution Adapter Cabinet design with hazardous risk assessments criteria according to the military standard specifications. Same analysis approach then modeled with Petri Nets that has extensions from fault tree analysis approach and enables the modeler to represent the probability of occurrences in the system design phase. Same model can be built in the specification phase which creates the potential for early validation of the system design behavior
