Formalization of Hybrid Systems Models for Port Terminal Management With Considering of Key Performance Indicators

Engineering Reports, Volume 7, Issue 1, January 2025.
New way of formalizing hybrid systems in models for managing the process of vessel unloading gives an ability to improve in sea ports container unloading technology and allow obtaining maximum results in terms of cargo processing speed. Concept of a hybrid control system makes possible to consider those features of the vessels unload process that have ...

Dynamic Force‐Shaped Input Control With Adjustable Maneuvering Time for Payload Transportation Systems

Journal of Control Science and Engineering, Volume 2025, Issue 1, 2025.
This work presents a novel dynamic input‐shaping methodology for crane control. A mathematical model is developed for a single pendulum system driven by a crane trolley, incorporating both kinetic friction and applied force dynamics. The force input function is specifically designed to achieve rest‐to‐rest payload transfer while meeting prescribed ...

Optimizing multiple equipment scheduling for U‐shaped automated container terminals considering loading and unloading operations

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 20, Page 3103-3124, 15 October 2024.
Abstract U‐shaped automated container terminals (ACTs) represent a strategic design in port infrastructure that facilitates simultaneous loading and unloading operations. This paper addresses the challenges of scheduling multiple types of equipment, such as dual trolley quay cranes (DTQCs), automated guided vehicles (AGVs), double cantilever rail ...

Closed‐loop stability analysis of deep reinforcement learning controlled systems with experimental validation

IET Control Theory &Applications, Volume 18, Issue 13, Page 1649-1668, September 2024.
This research investigates the closed‐loop stability of dynamic systems controlled by deep reinforcement learning agents through Lyapunov analysis and a linear‐quadratic polynomial approximation of the trained agent. The study validates its approach with simulations and experiments on real‐world hardware, confirming the deep reinforcement learning's ...

Vision based intelligent traffic light management system using Faster R‐CNN

CAAI Transactions on Intelligence Technology, Volume 9, Issue 4, Page 932-947, August 2024.
Abstract Transportation systems primarily depend on vehicular flow on roads. Developed countries have shifted towards automated signal control, which manages and updates signal synchronisation automatically. In contrast, traffic in underdeveloped countries is mainly governed by manual traffic light systems.
