Agent based simulation for C-AGVs at Intermodal Terminal / Agent baserad simulering för C-AGVs vid Intermodal Terminal

Syed, Ali Awais, Milants, Jan January 2009 (has links)
In recent history there has been a steady increase in container traffic worldwide. As a result modern western Container Terminal ports are turning towards automation to raise their productivity, capacity and reliability. Automated Guided Vehicles (AGVs) are among the most commonly used solutions for horizontal transport within a container terminal. A more recent development in the automated container handling is the use of cassette based or C-AGVs. The latest generation of which provides a zero emission, all electric solution through the use of induction recharge points in the terminal area. The Multi-Agent System (MAS) based simulation model provides a method for evaluating dispatching strategies for this newest generation of C-AGVs. The location and number of recharge points, cassettes, yard and quay cranes as well as the paths containers have to travel are all included in the model. The NetLogo based simulator will be used to compare existing dispatching strategies, modified versions of them, or develop and test new ones. The simulator will also simulate different scenarios, which are described in the later chapters, and can thus be used to determine the best configuration and investment plan in a highly complex domain like a Container Terminal. / s_aliowais@hotmail.com, jan.milants@kahosl.be 0046735781720 ; 003252213865

Analysis and Scheduling of machinery in an Intermodal Terminal by using the OSPF Concept

Khan, Osama Adnan Ghaffari January 2008 (has links)
The design of an Internet Protocol (IP) network is a long-term investment where many aspects must be taken into consideration. Some of them are the cost of the design, network sustainability and aspects regarding traffic engineering. When, its matter to design an IP network for an industry like Sea ports or Container Terminal than the factors related to traffic engineering and scheduling needs more attention. This thesis addresses the problems of designing and suggests a solution with IP network by using the concept of Open Shortest Path First (OSPF) routing algorithm. The routing in OSPF telecommunication networks is determined by computing shortest paths with respect to link weights sets by the network operator. In this research the shortest path computed on the basis of Current status, Current location, distance and cargo limitation of Automated Guided Vehicles that are using cassettes to transfer containers, which are called C-AGVs. A MATLAB based simulation tool is developed and is used to test and compare the OSPF algorithm to the general scheduling processes in a container terminal. The results show that using the OSPF concept it will yield in higher productivity. / osamaadnan79@hotmail.com + 46 737879001

Evaluating Layouts for Automated Transport System using Simulation Approach

Rashid, Rizwan, Kaleem, Babur January 2009 (has links)
Industries such as trade, manufacturing and transportation have undergone significant changes due to the globalization concept. Sea ports play a very important role in building and strengthening the economies of countries worldwide. Due to the high rate of production, the work load has increased at the ports which resulted into financial as well as capacity problems. As a result of such problems, cost optimized and automated solutions are being developed and introduced at the ports. In the horizontal transport system of the sea ports, AGVs are one of those automated solutions used to transport containers from ships to yard and vice versa. Newer and more practices are being employed to make the efficient transportation of these AGVs. Numexia has recently introduced a new version of Cassette AGVs called Zero-Emission C-AGV. A conceptual model is developed for Zero-Emission C-AGVs and different layouts are evaluated using multi agent-based simulation. The greedy algorithm has been used for the efficient dispatching of jobs. The Simulation will carry out the dispatching of jobs for C-AGVs between quay area and yard using different layouts and scenarios for the unloading operation.
