Abstract:
In order to improve system reliability, designers may introduce a system of different technologies in parallel. When each technology is composed of components in series, the architecture belongs to the series-parallel systems. This type of system has not been studied as much as the parallel-series ones. There exists no method dedicated to the reliability allocation in series-parallel systems with different technologies. We propose in this paper a study of this reliability allocation problem.
Introduction
Many researchers work to evaluate the reliability allocation in series, complex systems like Srinath (1985) , Subrie (1996) and Kalia (2004).
The process by which the failure allowance for a system is allocated in some logical manner its sub-systems and elements is termed reliability allocation. This problem is different from that determining the system reliability based on individual reliability values of the elements and sub – systems that constitute the system. The purpose of reliability allocation is to establish a goal or objective for the reliability of each component so that the manufacturers can have an idea of the performance required of this product.
