Optimization the Availability of a System with Short Circuit and Common Cause Failures
Redundancy allocation problem is one of the most important problem in Reliability area. In this problem the reliability and availability of the systems maximized via allocating redundant components to sub-systems. a systems operates normally in its operational mode but fails in either opened or shorted modes. this paper presents a repairable k_out_of_n systems network model with common cause fa...
متن کاملCommon Cause Failures and Ultra Reliability
A common cause failure occurs when several failures have the same origin. Common cause failures are either common event failures, where the cause is a single external event, or common mode failures, where two systems fail in the same way for the same reason. Common mode failures can occur at different times because of a design defect or a repeated external event. Common event failures reduce th...
متن کاملReliability analysis of static and dynamic fault-tolerant systems subject to probabilistic common-cause failures
Fault-tolerant systems designed with redundancy techniques are typically subject to common-cause failures, which are multiple dependent component failures caused by a shared root cause or a common cause (also known as a shock). There are two types of shocks: fatal and non-fatal. A fatal shock (FS) will fail all components of a system. A non-fatal shock (NFS) will affect only a subset of system ...
متن کاملCalculation and Analysis of Reliability with Consideration of Common Cause Failures (CCF) (Case Study: The Input of the Dynamic Positioning System of a Submarine)
Abstract The reliability and safety of any system is the most important qualitative characteristic of a system. This qualitative characteristic is of particular importance in systems whose functions are under various stresses, such as high temperature, high speed, high pressure, etc. A considerable point, which is rarely taken into account when calculating the reliability and safety of syst...
متن کاملGeneralized Stochastic Petri Nets for Reliability Analysis of Lube Oil System with Common-Cause Failures
A very high level of availab ility is crucial to the economic operation of modern power plants, in view of the huge expenditure associated with their failures. Th is paper deals with the availab ility analysis of a Lube oil system used in a combined cycle power plant. The system is modeled as a Generalized Stochastic Petri Net (GSPN) taking into consideration of partial failures of their subsys...
