This paper presents a system architecture which is based on the multi-agent system paradigm for solving complex problems. This architecture is applied to solve the port container terminal management problem, and specifically to solve the automatic container allocation. The multi-agent systems paradigm seems to fit this problem due to its inherent complexity. This work is part of a project for t...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

This paper deals with simulation modeling of the vessel traffic in Delaware River. The purpose is to study the impact of deepening on the navigational efficiency in the River. In this regard, vessel calls to terminals, lightering and barge operations, tidal and navigational rules in the River, terminal and anchorage properties as well as vessel profiles are considered in the model. The simulati...

The arrival and service process of vessels at container terminals is always a main concern for port managers. We present simulation model, which aims to shed light on this problem. On one hand, the model inputs describe number berths, as well ship arrivals services through its respective distributions. other outputs include: waiting times, queue lengths, berth utilisation efficiency ratio. An e...

Port, as a critical facilitator in international trade and logistics, plays a unique role in global supply chain activities. Maritime ports are exposed to many disruption sources such as natural disasters, labour strikes and terrorism. Disruptions in port can have a wide range of potential negative impact on its transportation networks; while sometimes also benefit other ports in close proximit...

This paper introduces a mixed integer programming model to find the optimum development plan for port Anzali. The model minimizes total system costs taking into account both port infrastructure costs and shipping costs. Due to the multipurpose function of the port, the model consists of 1020 decision variables and 2490 constraints. Results of the model determine the optimum number of berths tha...

This study is part of the project Improved Port/Ship interface (IPSI) , supported by the EU Commission. The general objective of the project is to strengthen the economic position of waterborne transport, especially short sea shipping. In the IPSI-concept, the terminal is the central point of inter modal logistic chains. This paper concerns a simulation study, with the overall objective to prov...

It is known that the collection of the specific needs of mobile users and location management in an electronic commerce recommendation system are important indicators used to evaluate user satisfaction and system execution efficiency. In order to improve the low accuracy of recommendation systems and ensure real-time location management, we proposed cooperative embedded data collection and cont...
