Data collected for 6 years （2009-2014）, HHI （Herfindahl-Hirschman index technique） was used to analyse the market behaviour and the movement of the market towards monopoly or to lead to PPC （pure and perfect competition）. Based on the above, by analyzing the defined market data, it was found to be a promising market and tends to competition. Of course, this serves the interest of the client, which is the efficiency and speed of cargo handling safely and at the lowest cost.展开更多

The primary data for the study were obtained from copies ofsurvey questionnaires administered to random sample of port users stratified by areas of specialisation. Hypotheses governing this study were based on the premise that additional port facilities provided and security measures adopted in compliance to ISPS code＇s requirements would have positive spillover effects on port operations. Evidence from data analysis indicated that compliance to ISPS code had positive effects on performance of operational performance of Nigeria ports. Similar effects were also observed inport users＇ satisfaction and profitability. The paper contributes by providing decision support framework for ports and terminals. monitoring and gauging outcomes of ISPS code administration in展开更多

Nowadays, Vietnam port-logistics sector has been becoming one of the most important service industries that contribute intensively to create value for Vietnam export goods in global market. This paper discusses one of the contemporary challenging issues for Vietnam--how to improve value chain through efficient port logistics. The objective of this research is to review literature issue of value chain, analyse the situation of Vietnam logistics sector, especially in port logistics and provide some recommendations to improve value chain of Vietnam export goods. The surveyed issues of both sides of logistics service providers （LSPs） and beneficial cargo owners （BCOs） will be taken into consideration. Based on the findings result, some actions are suggested to the government and local logistics service providers to make necessary decisions and solutions to improve value chain of Vietnam export goods through efficient port logistics.展开更多

It is helpful for the container terminals if lighter containers arrive earlier than heavier containers, because the latter can be stacked on the former. Therefore, the heavier ones can be loaded into the ships first. Shippers of marine containers do not, however, care for the matters of ships. They follow their own time schedules of supply chains sending marine containers with no relation to container weight. In addition to the conflict explained above, a ship must accommodate numerous containers sent by many shippers. Consequently, marshalling containers at container terminals before loading them into ships is necessary, although it causes inefficiencies of time and cost of cargo handling. This paper presents a proposal of a simple sequence of stacking marine containers at container terminals, adapting to random arrival of the containers irrespective of their weight, but it naturally keeps heavier containers stacked higher together with the stacking space minimized. An algorithm related to this proposal is the following： First, weight-ranked stacking addresses are assigned initially in a block of space at a container terminal; Second, containers are accepted and stacked up in the first block as they arrive at the terminal; Third, a lighter ranked address is sought for the next container if the number of containers on the initially assigned address for the container has already reached the maximum, which depends on the height of cargo handling equipment such as transfer cranes; Fourth, such containers are stacked up on the lighter ranked address. The address is reassigned with the weight rank of the container; Fifth, a heavier ranked address is sought for the next container if no lighter ranked address can be found; Sixth, such containers are stacked up on the heavier ranked address; Seventh, change the block to the next one if either a lighter or heavier ranked address cannot be found; Eighth, repeat the sequence above. This paper demonstrates the algorithm run by a simulation model for which actual arrival records of marine containers to a container terminal of Port of Yokohama are applied. Six ships of different sailing routes are analyzed using the simulation model. All analysis results show that heavier containers are stacked higher with a minimum number of blocks. Therefore, no marshalling of containers is necessary for loading the containers into ships.展开更多
