Ecolego - a toolbox for radioecological risk assessment

Ecolego is a MATLAB toolbox for modelling dynamic systems and to perform risk assessments using model simulations. The toolbox supports linear and non-linear systems, modelled in continuous time, sampled time, or a hybrid of the two. The Graphical User Interface of Ecolego facilitates the transition from a conceptual model, represented with an interaction matrix, to a mathematical model implemented in Simulink. Ecolego includes routines for probabilistic simulations, correlation between parameters, sensitivity analyses, uncertainty analyses and parameter optimisation. Even though the toolbox can be used to simulate any species and dynamic system, it has been specially designed to fulfil specific needs in the field of radioecological risk assessment. Ecolego includes a library with radionuclide data and it supports automatic consideration of radionuclide decay chains. This paper provides an overview of the functioning and features of Ecolego.
