Reliability engineering is known to have been first applied to communication and transportation systems in the late 1940's and early 1950's. Reliability is the probability that an item will perform a required function without failure under stated conditions for a stated period of time. Therefore a system with high reliability can be likened to a system which has a superior quality. Reliability ...
In this paper we develop a search procedure for redundancy optimization of reliability models. We consider those systems where the reliability cannot be evaluated exactly but must be estimated through Monte Carlo simulation. At each iteration, two neighboring configurations are compared and the one that appears to be better is passed on to the next iteration. The search procedure uses an incre...
Applying system-level fault-tolerant techniques such as active redundancy is a promising way to enhance the system reliability for safety-related applications. Embedded system design using active redundancy is a challenging task that involves solving two major problems, namely finding the optimal redundancy configuration and mapping/scheduling of the application (including the redundant compone...
This paper develops an efficient heuristic to solve two typical combinatorial optimization problems frequently met when designing highly reliable systems. The first one is the redundancy allocation problem (RAP) of series-parallel binary-state systems. The design goal of the RAP is to select the optimal combination of elements and redundancy levels to maximize system reliability subject to the ...
in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...
This paper divides the execution process of command post system into four stages: information acquisition, processing, decision control and response execution. It combines multilayer complex networks with a phased-mission system. Most studies have only evaluated reliability systems. evaluates optimizes In order to improve mission success rate maximize system, this provides multitasking node cri...
The SSAPRE algorithm for performing partial redundancy elimination based entirely on SSA form is presented. The algorithm is formulated based on a new conceptual framework, the fac-tored redundancy graph, for analyzing redundancy, and represents the rst sparse approach to the classical problem of partial redundancy elimination. At the same time, it provides new perspectives on the problem and o...
