Abstract | The rapid growth of container transportation is causing a
number of problems in container terminal . The need for
appropriate allocation of handling equipment for operations
such a s loading /unloading and l and transport from quays,
is widely recognized . Optimal allocation of equipment permits
the efficient operation of a terminal . Considerable
mathematical research has been done to meet this requirement.
Most of it ha s been carried out using either the queuing
theory or simulation techniques. However, with regard to the
former , t h e problem needed simplification whereas the latter
is time consuming and costly . Container handling is a complex
operation a nd many decisions have to be ma de every da y by day
or even by shorter period of time. The purpose of the study is
to determine the optimal allocation of handling equipment such
as mobile cranes , ship gears, and trailers, with the a id of
computer, in a container terminal. Further the purpose i s to
evaluate the efficiency of Bangkok port and make a comparison
with the theoretical outputs. A computer-based optimization
system was developed with the a id o f dynamic programming and
simulation techniques , applicable to container handling in a
port. The Lagrange Multiplier procedure was us e d to solve the
multi- dimensional dynamic programming problems , which was
found to be the most effective and the least computer time
consuming . Simulation was used to check the validity of the
system. It was found, through the validity check, that the
differences in outputs fall within a narrow range with a mean
of 1 TEU and a STD of 12 TEU . Despite in the case study a
large difference was found between the actual and theoretical
outputs . The system d eve lope d is applicable to any container
terminal in the world . Any numbers of berths, all kinds of
container vessels, cranes and trailers could b e accounted for
by mean s of t h e optimal solution . Although the two phase
optimization does not provide the optimal solution, it was
found to b e precise enough for real world cases. |
