Abstract According to the production requirements of a packaging line in distillery, this article designed suction tray gantry with width 1922mm, length 5000mm, and height 940mm using Solidworks software. Through ANSYS Workbench, performance advantages disadvantages made structural steel aluminum alloy under maximum load 100Kg required by enterprise are analyzed. Finally, through comparison the...

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

Increased customer demands have taken substantial effect on the formation of strategies for container terminal operations and in turn became important for performance evaluation of container terminals. This s...

This paper addresses the applications of different techniques for solving container terminals problems. We have built a simulation model that can be used to analyze the performance of container terminal operations. The proposed approach is intended to be applied for a real case study in Alexandria Container Terminal (ACT) at Alexandria port. The implementation of our approach shows that a propo...

In this research the rigid plastic material is applied to steady and nonsteady state strip rolling .Stresses and strains distribution in steady state plane strip rolling under the condition of constant of friction are calculated for work hardening and nonhardening materials .In order to attain a comprehensive understanding of the underlying process details, to check and select semi analytical m...

In this paper efficient in time methods for support decision-making processes in small container terminal operated by reachstackers are proposed. Two main problems are considered: first, minimization the number of loading/unloading operations between container trains and bays, second, minimization the number of re-handing operations within container bays. in Gliwice, Poland to model the problem...

Since the last two decades, container transportation system has been faced under increasing development. This fact shows the importance of container transportation system as a key role of container terminals to link between sea and land. Therefore, there is a continuous need for the optimal use of equipment and facilities in the ports. Regarding the complex structure of container ports, this pa...

An overview of literature is conducted on research focusing on improving the performance of container terminals. The growth of containerization has led to numerous decision problems for container terminal management to consider in operating their container terminals more efficiently, e.g. where to place a ship along a quay, scheduling the resources to work a ship, etc. The research papers revie...

We demonstrate the evolution of microstructure and deformation associated with the use of electrical methods for evaluating mechanical reliability of patterned interconnects on rigid substrates. Thermomechanical fatigue in aluminum and copper interconnects was induced by means of low frequency (100 Hz), high density (> 10 MA/cm) alternating currents, which caused cyclic Joule heating and associ...
