| Abstract | This study explored the possibilities of the three phase
modelling approach which was first described by Tocher in 1961.
Fashioned after this three phase concept, a simulation system
called Interactive Simulation System (ISSY) was developed and
implemented on a microcomputer. ISSY is primarily a discrete
simulation system with some of the essential facility and
flexibility of a high-level general purpose language. It is,
however , general enough to accommodate continuous and/or dynamic
systems models.
ISSY offers a simplified modelling style which greatly eases
the programming task of the analyst. The language and syntax
used during model encoding is natural to an extent that the logic
of the model is retained. This is accomplished inherently by the
three phase approach its elf and also through the use of long
variable names and logical if-then-else constructs in the model
code. ISSY uses a dynamic memory allocation scheme so t hat model
size is only limited by the memory of the computer. The ISSY
software was written in Turbo Pascal (BORLAND Intl., version 4.0).
To determine the merit of ISSY and consequently the three
phase modeling strategy , a case study was made on the problem of
port congestion at the Bangkok port . A model involving the seaside activities of this particular river port was formulated and
simulated. Various solution alternatives were considered in the
simulation runs and impact studies were made to quantify the
nature and extent of congestion at the port of Bangkok.
Alternatives on increasing crane rates, minimizing ship delays,
and adding berths were t he highlights. |
