Abstract: Common cause failure is an important phenomenon for a system with failure dependent parts. In this paper, several common cause failure models are analyzed and compared. A new common cause failure model for system reliability estimation is presented based on Bayesian Networks. Examples of series system, parallel system and series-parallel system are given to explain how to use the mode...

In this paper, a statistical model is presented for decision making in repairing water pipes network. The water distribution system has been considered as a “repairable” system which is under repeating failure modes. From this, a practical model for anticipating the failure of the water pipes in repairable systems has been presented using the trend renewal process concept. In this process, the ...

This paper aims at characteristic failure mechanisms of cohesive frictional materials at two levels of observation: (a) at the macroscale of continuum elastoplasticity, and (b) at the microscale of active microplanes with arbitrary orientation. Thereby, the criteria for the loss of uniqueness and the loss of ellipticity will be discussed for a macroscopic as well as a microplane-based anisotrop...

The lifetime of micro electro–thermo–mechanical actuators with complex electro–thermo–mechanical coupling mechanisms can be decreased significantly due to unexpected failure events. Even more serious is the fact that various failures are tightly coupled due to micro-size and multi-physics effects. Interrelation between performance and potential failures should be established to predict reliabil...

In this paper, we present the current state of a failure mode taxonomy, and discuss its potential to explore the failure mode space of aerospace applications. More fundamentally, we discuss what constitutes a good description of a failure that can be detected at the conceptual design stage. Elemental (physics-based) descriptions of failure modes are derived for several domains identified throug...

This paper outlines an approach to the identification of IT-related risk. The risk is identified from the perspective of the services provided by a software system to the users. The approach assumes the investigation of the service failures with the use of failure mode keywords. The service-based risk identification is supplemented with checklists extracted from standards and classical techniqu...
