Abstract
This research focuses on determining the optimal allocation of redundancies within a system, strategically placing them to enhance system performance. The paper explores redundancy allocation strategies through stochastic comparisons of resulting system lifetimes in various stochastic orders. While previous studies mainly focused on two or n-component series systems with some specific distributions for component lifetimes, this study extends the investigation with arbitrary distributions or some semiparametric families. It presents some new and extended results, offering novel insights to the topic.
期刊介绍：
Operations Research Letters is committed to the rapid review and fast publication of short articles on all aspects of operations research and analytics. Apart from a limitation to eight journal pages, quality, originality, relevance and clarity are the only criteria for selecting the papers to be published. ORL covers the broad field of optimization, stochastic models and game theory. Specific areas of interest include networks, routing, location, queueing, scheduling, inventory, reliability, and financial engineering. We wish to explore interfaces with other fields such as life sciences and health care, artificial intelligence and machine learning, energy distribution, and computational social sciences and humanities. Our traditional strength is in methodology, including theory, modelling, algorithms and computational studies. We also welcome novel applications and concise literature reviews.
