Engineering hierarchical complex systems: an agent-based approach. The case of flexible manufacturing systems

, 2012
This article introduces a formal model to specify, model and validate hierarchical complex systems described at different levels of analysis. It relies on concepts that have been developed in the multi-agent-based simulation (MABS) literature: level ...

Policy Capacity for Novel Technology Adoption: Developmental Insights From Singapore's AI Adoption in Long‐Term Care

Public Administration and Development, EarlyView.
ABSTRACT Worldwide, artificial intelligence‐driven technologies, including robotics and autonomous systems (RAS), are adopted to address manpower shortages in long‐term care. However, their effective use requires a reasonable degree of policy capacity across individual‐, organisational‐ and system‐levels.

A heuristic-assisted deep reinforcement learning algorithm for flexible job shop scheduling with transport constraints

Complex & Intelligent Systems
Automated guided vehicles (AGVs) are widely used for transportation in flexible job shop (FJS) systems, and their transportation task scheduling has the same substantial impact on production efficiency as machine scheduling does. However, traditional FJS

Modeling and Design of Container Terminal Operations [PDF]

, 2014
Design of container terminal operations is complex because multiple factors affect the operational perfor- mance. These factors include: topological constraints, a large number of design parameters and settings, and stochastic interactions that interplay

Real‐Time Terrain Traversability Analysis and Mapping for Autonomous Robotics in Dynamic Environments: Fusing Appearance‐ and Geometry‐Based Approaches

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents advanced methodologies for real‐time terrain analysis and mapping in autonomous robotic systems. The focus is on appearance‐based terrain traversability analysis and geometric‐based terrain traceability analysis. In the appearance‐based approach, an enhanced segmentation model using pixel‐based augmentation and 13 unique ...

Incidence, risk factors, and outcomes of numerical hypotony and choroidal effusion following PRESERFLO MicroShunt implantation

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the incidence, outcomes, and risk factors of numerical hypotony (NH) and choroidal effusion (CE) following standalone PRESERFLO MicroShunt (PMS) implantation. Methods Primary open‐angle glaucoma (POAG) and pseudoexfoliative glaucoma (PXG) patients with uni‐ or bilateral surgery at a tertiary university hospital were ...
