Step 3:
Implementing
your model
ModelMaker is designed to mimic the process of conceptual model
development as much as possible. The first step involves constructing
a diagram on the screen which represents the various model parts.
This diagram is composed of a series of ModelMaker components,
each of which is intended for a different type of mathematical
operation. Each component has a definition which can be edited to
insert its equation and any other appropriate information.
The next steps
Once your model has been implemented, it can be run; the equations
are solved, generating results that can be interpreted in graphs or
tables. Validation of your model may involve checking the model
results against observed data to test its predictive power. ModelMaker
provides a series of facilities to make this as straightforward as
possible.
In practice model development is often very iterative. Having tested
the model you are likely to find that some changes are required.
