An Integrated Numerical and Bollard Pull Evaluation Approach for Early‐Stage Resistance and Thrust Assessment of a Small Craft

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Early‐stage hydrodynamic assessment of slender multihull vessels is challenged by limited geometric maturity, uncertain propulsion integration, and strong sensitivity to operating conditions. Under such constraints, reliance on a single analytical or numerical method may lead to misleading design decisions due to oversimplification or ...

Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

Online Rebate Strategy for a Dual‐Channel Supply Chain

Naval Research Logistics (NRL), EarlyView.
ABSTRACT As online shopping channels become ubiquitous, consumers are faced with a vast number of digital purchasing options. To attract more consumers, many e‐shops utilize cashback websites (CWs) to provide online rebates. This study examines a dual‐channel supply chain, in which the manufacturer sells products through both its own online store and a

The 2‐D Orthogonal Packing Problem With Multiple Levels of Prioritization: A Spatial Optimization Perspective

Naval Research Logistics (NRL), EarlyView.
ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.
