Abstract: Decision-making using simulation can be difficult, if day-to-day decisions have to be made using lengthy simulation runs. In situations where decisions are required quickly, an auxiliary model of a simulation model, called the metamodel, can be used. This metamodel is a regression model developed using the inputs and outputs of the simulation model developed for a problem. In this study, simulation and metamodels of a real-life production scenario were developed and validated for the purpose of comparing the two methodologies. The validation results justified that the metamodel could be used to estimate the response variable accurately and quickly. Along with modelling and analysing the present operation, four alternative scenarios were developed and validated to explore the possibility of improving the operation. The metamodels developed can be used for effective decision-making without the need for any specialised software or training.
