The evaluation of model adequacy is an essential step of the modelling process because it indicates the level of accuracy (how closely model-estimated values are to the reference values) of the model estimations. This is an important phase either to build confidence in a model or to allow a selection of alternative models. The availability of appropriate software tools to assist model validation is needed since model testing is frequently either neglected or minimized in the context of model development and use. The freeware, Microsoft COM-based tool IRENE_DLL is a flexible tool providing extensive, integrated, statistical capabilities for use in model validation. The modular structure allows to use it via custom developed either applications or other components in a client-server architecture. Since IRENE_DLL was developed, the component-oriented paradigm has evolved, specifying new requirements in order to increase software quality, reusability, extensibility, and transparency for components providing modelling solutions in biophysical domains. This contribution is to illustrate the Windows .NET2 component IRENE (Integrated Resources for Evaluating Numerical Estimates) and an application which uses it, SOE (Simulation Output Evaluator).
