One technology that has been proposed is the use of Automated Guided Vehicles (AGVs) in the handling of containers within terminals. Recently, a new generation of AGVs, called C-AGVs, has been developed which makes use of cassettes that can be detached from the AGV. We have developed an agent-based simulator for evaluating the cassette-based system and com-paring it to a traditional AGV system. In addition, a number of different scenarios of con-tainer terminal equipment, e.g., number of AGVs and cassettes, have been studied in order to find the most efficient configuration. The simulation results suggest that there are confi-gurations which the cassette-based system is more cost efficient than a traditional AGV system.

The demand for energy request for the movement of transport is a necessity in the modern world. Transport and activity called transportation are used daily, everywhere, and a lot of energy is needed to power the various transport modes. Today different transport modes are being used to transport passengers and cargo. It is quite common to use road transport, which can transport passengers and cargo from door to door. Considering alternative possibilities (road, railway and/or inland waterway transport), it is important, based on theoretical and experimentation, to identify optimal solutions. In finding transport modes that are either most technically or economically effective, we could unearth possible solutions which would require minimal energy use. Unfortunately, with increased transportation, this often leads to traffic c...

Some technologies deemed attractive by large ports are: Artificial Intelligence (AI), Cloud Computing, Blockchain and Internet of Things (IoT). The objective of this paper is to review the “state-of-the-art” of scientific literature on digital technologies that facilitate operations management for container terminal logistics. The studies are synthesized in form of a classification matrix and analysis performed. The primary studies consisted of 57 papers, out of the initial pool of over 2100 findings. Over 94% of the publications identified focused on AI; while 29% exploited IoT and Cloud Computing technologies combined. The research on Blockchain within the context of container terminal was nonexistent. Majority of the publications utilized numerical experiments and simulation for validation. A large amount of the scientific literature was dedicated to resource management and scheduling of intra-logistic equipment/vessels or berth or container storage in the yard. Results drawn from the literature survey indicate that various research gaps exist. A discussion and an analysis of review is presented, which could be of benefit for stakeholders of small-medium sized container terminals.Supervisors: Lawrence Henesey and Emiliano Casalicchio.open accessCONNENCT2SMALLPORT

Cross reactivities of these monoclonal antibodies against various kinds of representative heterotrophic bacteria turned out to be relatively low by competitive ELISA. In contrast, these monoclonal antibodies were very specific for nitrifying bacteria used as antigens. By means of sandwich ELISA using different isotype monoclonal antibodies such as IgM and IgG 1 , calibration curves were successfully developed for quantification of nitrifying bacteria. It was shown that the obtainable lower limit of quantification of N. europaea and N. winogradskyi were 7.0 × 10 6 N/ml and were 6.0 × 10 5 N/ml, respectively. Nitrifying bacteria in activated sludge of advanced domestic wastewater treatment johkaso were counted by sandwich ELISA and MPN methods. The...

With increasing vessel sizes, cargo volumes and higher demand for supply-chain optimization, seaports are required to be more efficient and competitive. In the present study, a proposed solution incorporating IoT and Blockchain is considered into automating many of the activities in the load planning process, which is then evaluated via simulation. Real data is collected concerning different types of cargo for RoPax vessels with the intended goal of reducing planning time in a seaport. The results contribute as one piece of the mosaic on the avenue towards becoming a "Smart Port", which deploys various digitalization technologies in order to become a fully automated port. The suggested approach to be integrated, builds upon IoT sensors in combination with the lightweight version of a Blockchain to improve balance indicators on a trim of a vessel. A developed simulation tool was used for evaluating a number of scenarios, with each scenario run set to 2500 times. The simulation results indicate an improvement of 50-160% from the current load planning operations for RoPax vessels.

In this study, twelve monoclonal antibodies against Nitrosomonas europaea (IFO14298) and sixteen against Nitrobacter winogradskyi (IFO14297) were raised from splenocytes of mice (BALB/c). It was found that these antibodies exhibited little cross reactivity against various kinds of heterotrophic bacteria. The direct cell count method using monoclonal antibodies could exactly detect and rapidly quantify N. europaea and N. winogradskyi. Moreover, the distribution of N. europaea and N. winogradskyi in a biofilm could be examined by in situ fluorescent antibody technique. It was shown that most of N. winogradskyi existed near the surface part and most of N. europaea existed at the inner part of the polyethylene glycol (PEG) gel pellet, which had entrapped acti...

The first conversion step, the oxidation of ammonia to hydroxylamine is catalyzed by ammonia monooxygenase (AMO). To investigate the activity of ammonia oxidation, mRNA (designated as amoA) encoding a subunit of AMO was quantified by competitive reverse transcription (RT)-PCR. As a result, it was possible to detect and quantify amoA expression in cultured Nitrosomonas europaea and even complex microbial communities such as nitrifying bacterial aggregates by competitive RT-PCR. It was estimated that amoA concentration in cultured N. europaea was 2.3 × 108 copies·ml−1. Additionally, it was calculated that the copy number of amoA in nitrifying bacterial aggregates was 1.0 × 1012 copies·ml−1 (5.1 × 1010 copies·mg−1-dry weight). On the other hand, amoA expression in the natural activated sludge in a household Gappei-Johkaso was undetectable, whereas 16S r...

In forming decisions on transport co"idor choice, this paper proposes that transaction costs can be considered as an additional determinant in conducting transport corridor analysis. The application of transaction costs theory in analyzing the organizations and the transactions that occur, assists in indicating as to which governance structure results in higher efficiencies. Efficiency is seen as either the minimisation on costs or the maximisation of customer service levels. The use of multi-agent based simulation for modelling the organisational structure and mechanisms provides a novel approach in understanding the relationships in a regional transport co"idor.

Defection is either cargo exposure to radiation, physical damages such as holes, punctured surfaces, iron surface oxidation, etc. The system uses a sorting array triangulation technique (SAT) and surface damage detection (SDD) to conduct the inspection. This new technique saves time and money on finding damaged goods during transportation such that, instead of running n inspections on n containers, only 3 inspections per triangulation or a ratio of 3:n is required, assuming n > 3 containers. The damaged stack in the array is virtually detected contiguous to an actually-damaged cargo by calculating nearby distances of such cargos, delivering reliable estimates for the whole local stack population. The estimated values on damaged, somewhat damaged and undamaged cargo stacks, are listed and profiled after being sorted b...

The simulation tool, called SimPort, is a decentralized approach to simulating managers and entities in a container terminal. Real data from two container terminals are used as input for evaluating eight transshipment policies. The policies concern the sequencing of ships, berth allocation, and stacking rule. They are evaluated with respect to a number of aspects, such as, turn-around time for ships and traveled distance of straddle carriers. The simulation results indicate that a good choice in yard stacking and berthing position policies can lead to faster ship turn-around times. For instance, in the terminal studied the Overall-Time-Shortening policy offers fast turn-around times when combined with a Shortest-Job-First sequencing of arriving ships.

Logistics companies and government agencies are no exception to the use of IT tools. The internet is radically changing the way business is being done and continues to do so. This paper presents the current work from an EU financed project called OVERSIZE, which investigates the current methods for interconnecting ports and destination within the Baltic region with their partners and assesses such information community systems. The application of a methodology based on knowledge engineering, called commonKADS is reviewed in the case study. The use of information broker systems offers advantages such as minimizing telecommunication and communication costs. In addition, the administration costs can be minimized if information is automated to provide logistics customers with availability information and schedules, manage bo...

The objective is to identify number of automated guided vehicles and cassettes required in order to that a number of cranes will not be idle during ship loading and unloading operations. A protocol called Contract Net is evaluated in the coordination of cassettes with automated guided vehicles, which are represented as agents in a simulator. The simulation tests show that under various scenarios a high throughput of container handling is achieved using cassettes, which act as a moving buffer while coordinating with IPSI AGVs

It is the backbone for all specialisation of science, medical and engineering concepts. Currently, the reading and learning method through AR-based approaches are quite highly intensive than the existing methods such as papers, books and magazines. This strategy is more expensive but it is more interactive to the user in understanding the root concepts in an effective manner. This paper explores the experiment on solar system revolution pattern along with 3D audio effect in spatial dimension. This novel idea inculcates more vibrancy in the current generation of students to understand the concepts with the clear illustrations and demonstrations.

Often the container terminal operations are changing to meet increased customer demands as well as to adapt to new technologies. This paper proposes a simulation model for container terminal system analysis. A simulation model is developed, called SIMPORT, which uses a Multi-Agents Systems approach that provides a modular and scalable method of modeling the entities in the container terminal domain. SIMPORT is used to test various berth assignment management polices and yard stacking management policies in the context of a case study of a major container terminal in India. The results indicate that by arranging the stacks according the ‘ship profile’, the port in India was able to reduce the waiting time of container ships and thus save costs. The increasing costs of container terminal development do justify the use of computer simulation to assist in planning and policy...

The alternative solution to increasing capacity other than physical expansion is via increased terminal performance so that containers are loaded, discharged, stored, and dispatched efficiently whilst optimizing available resources. The automatic planning of the operations of a container te rminal via market-based allocation of resources may greatly benefit the container terminal in satisfying its objectives and meeting its goals. The proposal is that a Multi-Agent System approach would offer port or terminal managers a suitable tool to plan, coordinate, and manage the container terminal domain. There exists a variety of inputs and outputs, actors, intrinsic characteristics and a large number of combinations of factors influencing the output that makes it quite difficult to conduct analysis. In the suggested approach,...
