1. A method of modelling system behaviour of a physical system, the method including, in one or more electronic processing devices:

  • a) obtaining quantified system data measured for the physical system, the quantified system data being at least partially indicative of the system behaviour for at least a time period, the quantified system data including measured attributes of a physical system obtained from sensor data received from sensors;

    b) forming at least one population of model units, each model unit including model parameters and at least part of a model, the model parameters being at least partially based on the quantified system data, each model including one or more mathematical equations for modelling system behaviour;

    c) for each model unit;

    i) calculating at least one solution trajectory to the one or more mathematical equations for at least part of the at least one time period;

    ii) determining a fitness value based at least in part on the at least one solution trajectory; and

    ,iii) iteratively modifying the model unit over a number of generations in accordance with the fitness value of each model unit by modifying at least one of;

    (1) at least part of the model; and

    ,(2) the model parameters; and

    ,d) selecting a combination of model units using the fitness values of each model unit, the combination of model units representing a collective model that models the system behaviour.
