Full-span Pre-cast
and Launching Method (FPLM) is a newly developed construction technique
that has been introduced from Korea by Bureau of Taiwan High Speed Rail
(BOTHSR). Due to the pre-cast production of box girder used in the
project, it’s necessary to make a capacity planning of the box girder
based on the progress requirements and the current launching condition
of the project. FPLM which will be implemented successfully or not
involves lots of factors, such as production facilities, circulation
planning of the pre-cast factory, elongation of pre-stress etc…Every
factor affects each other and the influence will result in difficulties
of cost estimation, production and launching performance. With the
progress of the construction, the procurement behavior of the pre-cast
factory from its raw materials suppliers exhibits a dynamic
change. This study aims to explore the behavior pattern of the supply
chain starting from materials procurement, processing, final production
of box girder to launching engineering. Furthermore, the method adopted
in this study is a breakthrough from the traditional way of static
thinking mode into a concept of dynamic feedback loop of System
Dynamics. A supply chain model established by utilizing a system
dynamic software, “PowerSim” will thus provide the decision maker with a
computer aided tool to simplify complicated mathematic calculation and
enables the users to make fast simulation and decisions. Finally, by
performing a sensitivity analysis on various influential factors of the
system model, this study intends to find the key factors which pose more
influence on the system, and to further explore the degree of influence
the key factors have on the completion date and the cost of the
project. |
