This project has proved conclusively that discrete event
simulation techniques can be used to simulate, on computer, a
complex stochastic materials handling system. The packing,
automatic palletising and warehousing departments of a large
powders manufacturing factory was used as an example to
investigate the capabilities of computer simulation.
The company intends to increase the number of packing machines
from seven to eleven, and has embarked on productivity
improvement projects that aims to increase the average packing
efficiency from the current 50%, to 60% with a long term goal of
70%. Due to the stochastic nature of the run and stop durations
of the packing machines, it was impossible to predict the effect
of the increased throughput on the palletising system by
conventional means.
The system was modelled on computer using the SIMAN simulation
language. Extensive research was initially carried out in order
to determine the operating parameters of the system. The
generation of cases from the packing machines in the program was
verified against actual production runs.
Various alternatives were analyzed to assist in decision making
on the expansion of the palletising system in order to
accommodate the increased throughput expected from the packing
floor. The simulation was therefore used to increase the capacity
of the automatic palletising system at minimal cost while meeting
demands from the packing floor. It was established that the only
capital expenditure required would be about R500 000 to increase
the capacity of a palletiser and to provide a pallet conveyor to
transport 40% of the pallets to direct despatch. / Thesis (M.Eng.)-University of Durban-Westville, 1989.
