over the years, there has been an obvious pollution problem in lagos area, nigeria with high population of over eleven million and the near absence of waste management infrastructures. concentrations of some pollution parameters and trace elements (temperature, ph, salinity, so42-, no3-, po43-, f-, do, bod, cod and coliform, cr, co, ni, ag, cd and pb) were determined from water bodies of isolo ...

Despite the growing role of barge transportation in the hinterland access of major seaports in Northwestern Europe, service network design for intermodal barge transportation has received little research attention. In this paper, a decision support model for service network design in intermodal barge transportation is presented. The model determines optimal shipping routes for roundtrip service...

Seaport terminals recognise the need to change current practices in order to improve regional air quality while enhancing their terminals’ competitiveness. One area that terminals can do better at is to improve their yard crane operations and in turn reduce the trucks in-terminal delay. This study examines various container rehandling strategies by the yard cranes with the goal of improving the...

Environments can range from low peclet numbers in which diffusion is predominant to high peclet numbers in which turbulence and advection occur. Control algorithms deployed on robotic platforms to monitor spatiotemporal distributions are often very specific to a particular peclet number environment and suffer reduction in efficiency when used in another peclet number environment. This paper inv...

This paper proposes a re-conceptualization of the port supply chain as a smart service system, in accordance with the theory of service science. Starting from a short literature review about the port supply chain approach and service science, a new comprehensive framework is provided to better understand seaport dynamics and the creation of competitive port supply chains. The methodology used i...

This research paper aims to study the correlation between the transportation infrastructure and regional economic activity. It emphasizes on the seaport activity and the activities of the different services sectors. By comparing trends between them and analyzing the causality relationships between the port traffic and the other economic sectors, our study tends to present how the activity of th...

Little is known about the magnitude of China’s SOE labor redundancy and the patterns and determinants of job creation. Such knowledge gap makes it difficult for decision-makers to provide prescriptions for China’s labor problems. This paper uses a panel data of Chinese provinces between 1986 to 1996 to estimate China’s SOE labor redundancy, and patterns and determinants of job creation in China...

Most of the operational problems in container terminals are strongly interconnected. In this paper, we study the integrated berth allocation and quay crane assignment problem in seaport container terminals. We will extend the current stateof-the-art by proposing novel set partitioning models. To improve the performance of the set partitioning formulations, a number of variable reduction techniq...
