The purpose of the work is to improve technology optimize functioning container terminal. An important role in terminals played by yards, together with personnel who handle loading and unloading operations containers their sorting. working same, but there are many new devices that can be used for sorting accounting containers. methodology. interaction between workers, technical means transport ...

This article presents a study of optimal control strategies for an energy storage system connected to a network of electrified Rubber Tyre Gantry (RTG) cranes. The study aims to design optimal control strategies for the power flows associated with the energy storage device, considering the highly volatile nature of RTG crane demand and difficulties in prediction. Deterministic optimal energy ma...

n A new antenna and radar-cross-section measurements facility consisting of four anechoic chambers has recently been constructed at Lincoln Laboratory on Hanscom Air Force Base. One of the chambers is a large compact range facility that operates over the 400 MHz to 100 GHz band, and consists, in part, of a large temperature-controlled rectangular chamber lined with radar-absorbing material that...

Transshipment yards, where gantry cranes allow for an e cient transshipment of containers between di erent freight trains, are important entities in modern railway systems and facilitate the general shift from point-to-point transport to hub-and-spoke railway systems. Modern rail-rail transshipment yards accelerate container handling, so that multiple smaller trains with equal destination can b...

The objective of the present work is to find a Collision Detection algorithm to be used in the Virtual Reality crane simulator (UVSim ®), developed by the Robotics Institute of the University of Valencia for the Port of Valencia. The method is applicable to boxshaped objects and is based on the relationship between the colliding object positions and their impact points. The tool chosen to solve...

Container terminal (CT) operations are often bottlenecked by slow YC (yard crane) movements. Efficient YC scheduling to reduce the PM waiting time is therefore critical in increasing a CT’s throughput. This paper develops an efficient continuous time MILP model for YC scheduling. The model treats realistic operational constraints such as multiple inter-crane interference, fixed YC separation di...

Giàn cần trục dành cho điện phân đồng (CE) hoạt động như một robot ở các nhà xưởng để vận chuyển và lắp ráp tấm cathode, anode. Vì được sắp xếp dày đặc nên khi di có sự dao lớn dẫn đến khả năng định vị thiếu chính xác, thậm chí gây mất an toàn. Bài báo đề xuất sử dụng bộ điều khiển PID kép với thông số chỉnh tối ưu hóa qua giải thuật truyền (GA) giàn trục. Bộ đầu tiên kiểm soát của tải trọng, c...

In this paper we discuss the design, control, and experimentation of internally-actuated rovers for the exploration of low-gravity (micro-g to milli-g) planetary bodies, such as asteroids, comets, or small moons. The actuation of the rover relies on spinning three internal flywheels, which allows all subsystems to be packaged in one sealed enclosure and enables the platform to be minimalistic, ...

Model predictive control (MPC) is a well-known control technique, which has been applied to complex and nonlinear processes. Fuzzy predictive control incorporates fuzzy goals and constraints in MPC, by combining predictive control with fuzzy decision making. In this paper, we propose the integration of weighted criteria in fuzzy predictive control, where the decision-maker can specify the prefe...
