Availability Equivalence Analysis of a Repairable Series-Parallel System
This paper studies the availability equivalence of different designs of a repairable series-parallel system. Under the assumption that the system components have constant failure rates and repair rates, we derive the availability of the original and improved systems according to reduction, increase, hot duplication, warm duplication and cold duplication methods, respectively. The availability e...
متن کاملAvailability Equivalence Factors of a General Repairable Parallel-Series System
The availability equivalence factors of a general repairable parallel-series system are discussed in this paper considering the availability function of the system. The system components are assumed to be repairable and independent but not identical. The life and repair times of the system components are exponentially distributed with different parameters. Two types of availability equivalent f...
متن کاملAvailability Analysis and Design Optimization for a Repairable Series-parallel System with Failure Dependencies
In this paper, the design of a repairable series-parallel system with failure dependencies is studied. The key point is that failure dependency and limited repair teams can affect the state transition rates of each subsystem, and thus affect the state distribution of the subsystem and the availability of the system. Taking this into consideration, we present a dependence function to determine t...
متن کاملAvailability Optimization of a Series Repairable System with Multiple k-out-of-n Subsystems
An availability model is developed to optimize the availability of a series repairable system with multiple k-out-of-n subsystems in this paper. There are two types of decision variables that determine the system designer’s decision to allocate the number of repairmen and to allocate the number of redundant components in each subsystem in the presence of weight, volume and cost constraint...
متن کاملEquivalence factors of a parallel-series system
This paper discusses the reliability equivalences of a parallelseries system. It is assumed that the system components are independent and identical. Each has a constant failure rate. We assumed three different method to improve the system. Both the reliability function and the mean time to failure are used to derive two types of reliability equivalence factors. We also obtain the fractiles of ...
