Computer experiments
An increasing number of systems are modelled via complex computer codes, particularly where real experiments are infeasible (too expensive, dangerous or just not possible).
An increasing number of systems are modelled via complex computer codes, particularly where real experiments are infeasible (too expensive, dangerous or just not possible).
Examples are engineering, environmental and climate models, geophysical models, chemical dynamics and disease models. The computer models are usually based on complex mathematics and have many different inputs. To explore and understand the models, experiments are performed where a design consists of combinations of values of the input variables. New statistical methodology is being developed to address the challenges from increasingly complex computer models.
