Parameterized modeling is not available
in the SimaPro Compact, Faculty and Classroom versions.
How you use parameters
Parameters can be defined on 3 levels (process, project
and database). You start by defining a parameter name and
giving it a default value. You can add uncertainty data as
well.
Defining
parameters and expression
Using the parameters, you can define expressions For
example, Weight=Volume x Density. You can use a wide range
of mathematical expression to create for example non linear
relationships.
With expressions you can also create switches, for
example to easily switch between electricity models in
different countries.
Once you have defined the parameters, you can use them in
processes and product stages. Simply type the name of the
parameter you want, or use the right mouse menu. SimaPro
will show the corresponding default values of the parameter
or the expressions.
Use of
parameters in modeling
The real power of parameterized modeling is in the
analytical features. You can simply create scenarios in
SimaPro, and set a value for each parameter used. You can
even add uncertainty values for each parameter.
Creating a
scenario analysis with parameter variation
The results are presented in graphical or tabular formats
and can be further analyzed. Of course you can easily copy
and paste all results.
Results of a
scenario analysis
Parameterized
modelling in SimaPro lets you model all kinds of
relationships in your inventory data. This offers many new
possibilities for simplifying your work.
