Plackett–Burman technique for sensitivity analysis of many-parametered models

A method for sensitivity analysis of a simulation model is presented, together with an illustrative example. The Plackett–Burman technique allows the concurrent consideration of numerous parameters. The required number of model scenarios necessary for completion of the analysis is approximately twice the number of parameters. Advantages to the technique include simultaneously investigating all parameters, as well as acquiring information about two-way parameter interactions, by means of a relatively small number of scenarios. A drawback is aliasing among interactions, which may confound interpretation.
