Abstract
The stochastic dynamic inventory-routing problem (SDIRP) is a fundamental problem within supply chain operations that integrates inventory management and vehicle routing while handling the stochastic and dynamic nature of exogenous factors unveiled over time, such as customer demands, inventory supply and travel times. While practical applications require dynamic and stochastic decision-making, research in this field has only recently experienced significant growth, with most inventory-routing literature focusing on static variants. This paper reviews the current state of research on SDIRPs, identifying critical gaps and highlighting emerging trends in problem settings and decision policies. We extend the existing inventory-routing taxonomies by incorporating additional problem characteristics to better align models with real-world contexts. As a result, we highlight the need to account for further sources of uncertainty, multiple-supplier networks, perishability, multiple objectives, and pickup and delivery operations. We further categorize each study based on its policy design, investigating how different problem aspects shape decision policies. To conclude, we emphasize that large-scale and real-time problems require more attention and can benefit from decomposition approaches and learning-based methods.

Abstract
Measuring water motion is essential for oceanography, coastal engineering, and marine environmental monitoring. A wide range of sensing technologies is used to quantify water velocity, wave motion, and flow dynamics, each suited to specific spatial and temporal scales. This paper presents a comprehensive review of modern sensor technologies for marine flow measurement, covering mechanical, electromagnetic, pressure-based, acoustic, optical, MEMS-based, inertial, Lagrangian, and remote-sensing approaches. The operating principles, strengths, and limitations of each technology are examined alongside their suitability for different environments and deployment platforms, including moorings, buoys, vessels, autonomous underwater vehicles, and drifters. Special attention is given to rapidly advancing fields such as MEMS flow sensors, multi-sensor fusion, and hybrid systems that combine inertial, acoustic, and optical data. Applications range from high-resolution turbulence measurements to large-scale current mapping and wave characterization. Remaining challenges include biofouling, performance degradation in energetic shallow waters, uncertainties in indirect velocity estimation, and long-term calibration stability. By synthesizing the state of the art across sensing modalities, this review provides a unified perspective on current technological capabilities and identifies key trends shaping the future of marine flow measurement.

Abstract
The advent of real-time telematics and advanced analytics has transformed maintenance in heavy-duty transport. Predictive maintenance systems now demand both reliable short-horizon failure alerts and precise Remaining Useful Life (RUL) forecasts to optimize service schedules, minimize operational risk, and support sustainability goals.This work tackles two complementary prognostic tasks under realistic deployment constraints: imminent-failure classification and continuous RUL estimation, using a recently released Scania truck dataset. The classification task must cope with extreme class imbalance and a cost structure that heavily penalizes overlooked failures far more than false alarms. Meanwhile, RUL estimation faces its own challenges: highly skewed target distributions, right-censored data, and shifting degradation dynamics across a diverse fleet.We propose a framework that integrates (1) a cost-sensitive Light-GBM classifier to minimize real-world misclassification expenses, and (2) a three-stage XGBoost regression ensemble in which each model specializes in one of three phases - healthy, early-degradation, or late-degradation - and uses log-transformed targets along with upweighted late-stage samples to stabilize training and prioritize critical short-horizon accuracy.Under a deployment-like validation protocol, the classifier achieved an AUC of 0.8024 and cut average misclassification cost by 27% versus a "one-class-early"benchmark. The RUL ensemble reached a global MAE of 19.8 time steps (10.4 within the final 20 steps) and demonstrated steadily improving precision as failure approached. These results confirm that cost-driven, health-stage-specialized models can deliver robust prognostics for industrial applications. © 2026 Copyright held by the owner/author(s).
