With the increase of container terminals, terminal supplies are being distributed. Hence, the competition among each terminals to preserve existing quantity of cargo goods and to attract new quantity of cargo goods is becoming fierce.
According to this, various methods to manage container terminal cargo goods and to attract cargo goods are being considered. In order to increase productivity and maximize efficiency of container terminals, efforts are being made to expand latest quay crane and to develop latest container terminal Pooling System.
There are various factors that can affect increase in productivity of container terminals. Among these, in the case of the yard transfer equipment, if the system changes to a Pooling System which is changing from allocating fixed number of YT(Yard Tractor) and SHC(Shuttle Carrier) to a specific GC(Gantry Crane) to distributing YT and SHC accordingly to a number of GC, the terminal productivity and fusibility of the transfer equipment can be increased.
The purpose of this study is to maximize GC(Gantry Crane) productivity using transfer equipment in container terminal. In order to achieve this, the transferring work has to be done smoothly without the GC having to wait. The study provides algorithm of Non Pooling System and Pooling System transfer equipment assignment in vertical and horizontal container terminal. Moreover, the study aims to propose optimized algorithm of pooling system and work operation form that can run the transfer equipment efficiently in container terminal and increase productivity of it.
For the research method, various archives and actual studies were analyzed related to container terminals. In order to analyze work of container terminals, actual vertical and horizontal container terminals being operated domestically were examined and analyzed.
Moreover, in order to efficiently operate transfer equipments which is the essential machine in container terminal, this study proposes appropriate work assignment model for vertical and horizontal container terminals. The effect of transfer equipment pooling system's algorithm that was proposed was examined and was applied to actual operating vertical and horizontal container terminals in the Non Pooling System operating method and Pooling System operating method algorithm model and the transfer equipment's work environment was composed to suit the actual condition. Within this context, final supplies, average berth time of command ship, maximum/minimum/average insertion algebra of transfer equipment were set to compare terminal productivity scale.
As a result of comparing and evaluating GBP(Gross Berth Productivity), GP(Gross Productivity) and NP(Net Productivity) which are indicators of productivity KPI(Key Performance Indicators) of container terminals, the command ship and period productivity indicator of vertical and horizontal container terminal run by Pooling System and by Non Pooling System is more efficiently run in the Pooling System hence the container terminal productivity indicator is formed higher.
As a result, when the Pooling System transfer equipment assignment algorithm is applied to the vertical and horizontal container terminal, the GBP(Gross Berth Productivity), GP(Gross Productivity) and NP(Net Productivity) indicators are formed highly.
By increasing productivity through applying the transfer equipment Pooling System, the terminal business can continue to increase service quality an profitability.
