The PSE Model-Based Innovation Prize 2021

Judgement criteria and judges' comments

Papers were judged against the following specific five criteria, taking into account the general guidelines published on the PSE website:

  • Innovation with respect to model-based concepts [25%]
  • Innovation with respect to construction and application of gPROMS® models [25%]
  • Innovation with respect to integration, use and implementation of model-based activities [25%]
  • Scope and significance of the results obtained [15%]
  • Overall scientific interest and relevance [10%].

As by definition the papers have already been reviewed and accepted for publication they are deemed to have scientific merit, and were thus not judged explicitly on this criterion other than to award ‘tie-breaker’ points in the last category.

Implicitly taken into account were the modelling themes that PSE is promoting for advanced process modelling and model-based innovation in general:

  • high-fidelity modelling, going to chemical engineering first principles where possible
  • model validation using experimental data in order to integrate theoretical models to observed values
  • multipurpose process modelling – i.e. using the same model for a variety of model-based activities in order to enhance return on modelling investment.
