摘要

基于可靠性的设计与工程系统的性能分析有关。冗余分配问题是基于可靠性的设计方法中最常见的问题之一。冗余分配问题决定了系统中组件的冗余级别,以最大限度地提高系统可靠性,并受到若干约束。近年来,利用进化元启发式算法求解与可靠性相关的冗余分配问题受到了经典数学方法的广泛关注。元启发式已经显示出在优化问题中获得精确解的潜力,并且在文献中应用了许多技术来实现最优冗余分配。本文提出了一种新的Jaya优化算法用于冗余分配,以最大限度地提高系统的可靠性。Jaya算法是一种简单的、基于群体的智能元启发式算法,由单个阶段和特定于算法的无参数算法组成。应用Jaya算法从文献中寻找具有非线性约束的两个冗余分配问题的最优解,使系统可靠性最大化。第一个问题是燃气轮机的超速保护系统,其控制系统被建模为四级串联系统。目标是在成本和重量约束下确定保护系统阀门的最佳冗余水平。二是具有体积、重量和成本约束的五级串联系统的冗余分配问题。通过将结果与另外两种元启发式方法进行比较,验证了结果。

Solving Redundancy Allocation Problems using Jaya Algorithm
Reliability-based design is related to the performance analysis of engineering systems. The redundancy allocation problem is one of the most common problems in the reliability-based design approach. The redundancy allocation problem determines the redundancy level of components in a system to maximize system reliability, subject to several constraints. In recent years, obtaining solutions to reliability-related redundancy allocation problems by means of evolving meta-heuristic algorithms has appealed to researchers due to the several drawbacks of classical mathematical methods. Meta-heuristics have shown the potential of obtaining precise solution in optimization problems and many techniques have been applied in the literature for optimal redundancy allocation. In this paper, a recently developed Jaya optimization algorithm is proposed to be applied for redundancy allocation to maximize system reliability. The Jaya algorithm is a simple, population-based intelligent meta-heuristic algorithm consisting of a single phase and an algorithm-specific parameter-less algorithm. This paper aims to present an application of the Jaya algorithm for searching the optimal solution of two redundancy allocation problems from the literature with nonlinear constraints so that system reliability is maximized. The first problem is the over speed protection system for a gas turbine, whose control system is modelled as a four-stage series system. The objective is to determine the optimal level of redundancy of the valves of the protection system under cost and weight constraints. The second one is the redundancy allocation problem of a five-stage series system with volume, weight, and cost constraints. The results are validated by comparing them with two other meta-heuristics.
