Evaluating options to increase production of a copper smelter aisle: A simulation approach

A case study involving the use of simulation to analyze options to increase production of a copper production facility in Australia is reported here. A detailed and accurate model was developed capturing the factors affecting production and materials handling. The study resulted in prototype software with an Excel-based interface that allows the user to do further experiments with the model. Animation was used throughout the life cycle of the simulation. The paper illustrates various modeling issues faced and how they were resolved in the modeling of this copper production process. The model allows for experimenting with many options to increase production, including change of pot sizes, casting rates, storage, and other resources' capacities. The study is an example for the usefulness of computer simulation technology to analyze manufacturing systems.
