processes. Stochastic discrete event simulation
allows the modelling of uncertainty and dynamic
systems and it is also flexible in modelling various
levels of detail and complexity (Awuah-Offei, 2012
and Awuah-Offei et al, 2012).
In this paper a stochastic simulation model is built
with Arena® simulation software to forecast
production at AG pit of PMGL. The model catered
for the random behaviour of excavators and trucks
in the pit and targeted a minimal variance between
planned production and actual production.
