Yard crane is an important resource in container terminals. Efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. This paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is NPHARD in nature. In other words, one of the most important constraints in...

Loads and working conditions of the trapezoidal cross-section of 36 m span crane beam can be analyzed by finite element method. Firstly, analysis of the stress and deformation is completed under the dangerous condition of crane beam based on the ANSYS software; secondly, find out the stress concentration and fatigue crack sensitive area of the bearing; finally, capture the position of fatigue c...

This paper discusses the development of control systems with hardware-in-the-loop simulation (HILS) method for enhancing the teaching of control engineering. Two control systems based on the HILS approach were developed namely simulated plant HILS (SP-HILS) and simulated controller HILS (SC-HILS) control systems. The SP-HILS control system uses an actual hardware of the controller and the plant...
