Shannon differential entropy properties of consecutive k-out-of-n:G systems
This research delves into the Shannon differential entropy properties of consecutive -out-of-:G. Initially, an expression for the entropy of the lifetime of a consecutive -out-of-:G system is formulated, providing a comprehensive understanding of its entropy characteristics. A characterization outcome is also derived. Furthermore, useful bounds are provided for the entropy of the lifetime of these systems. A nonparametric estimator for the new entropy metric is developed to assist in practical application. The effectiveness of this estimator is demonstrated through the use of simulated datasets, followed by a numerical illustration using a real-world dataset.
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.
