arXiv:2607. 15229v1 Announce Type: new Abstract: We develop data-driven algorithms for maintaining $N$ independent identical machines under a \textit{block replacement policy}, in which each machine is replaced upon failure and all machines are jointly replaced at regular intervals of length $k$.
arXiv:2608. 02509v1 Announce Type: cross Abstract: Sequential decision-making in real-world applications often involves uncertainty about the environment's model.
arXiv:2607. 27626v1 Announce Type: new Abstract: Safety-critical IoT systems such as industrial closed-loop control, V2X coordination, and remote teleoperation require every sensor's peak Age of Information (peak AoI, also abbreviated PAoI) to stay below a hard per-slot deadline, not merely an average bound.
Sequential decision-making in real-world applications often involves uncertainty about the environment's model. Uncertain Markov decision processes (UMDPs) represent the possible environments as a set of MDPs with shared states and actions but potentially different transition probabilities and rewards.
The paper presents a hierarchical Bayesian optimization framework that uses Gaussian process meta-modeling to address the challenges of optimizing complex system-of-systems (SoS) architectures. It handles discrete architectural choices, conditional dependencies, and heterogeneous design variables, improving search efficiency and robustness over conventional surrogate-based methods. The approach is demonstrated on an aircraft-based multi-agent system for wildfire suppression, showing its applicability to large, diverse design spaces with limited simulation budgets.
