LINE BALANCING IMPROVEMENT IN THE WELDING SECTION OF A CAR 91
5.3 QUEST Simulation Model
Based on the conceptual model and the details on type of processes, process time
and its distribution, labour assignment, and process precedence relationship, the
simulation model for the current system was built using the QUEST software. In
general, six basic elements were used to build the basic model. They are machine,
labour controller, labour, buffer, source and sink.
The simulation model is built upon these assumptions:
(i) Welding station is considered a machine and operator working at welding
station is modelled as labour.
(ii) Parts produced is set to have a constant inter-arrival time of 500 seconds.
They are sent to buffers to ensure continuous material supply such that
these buffers can be considered as trolleys placed near work stations.
